Message from the ChairOut of Sight,but not Out of MindJohn KiviniemiWhen I hear the term buriedassets, it evokes thethought of buried treasure– swashbuckling pirate movies withmaps where X marks the spot. Thisissue of NC Currents focuses on thechallenges of the water industry in termsof managing underground infrastructureor what is often referred to as ‘buriedassets.’ Beyond the installation of new(pipeline) construction, this most oftentakes the form of rehabilitation of agingpipeline via traditional dig and replacemethodology or, more recently, viatrenchless technology. Through theaid of modern geographic informationsystem (GIS) capabilities of many utilities,maps provide direction in the field, but,unfortunately, all too often in the utilitybusiness, X does not always mark thespot. Or, worse yet, the buried asset youlocate may not be the one you intendedto find. It can give new meaning tothe term ill-gotten booty. But, one factremains, infrastructure constructionand rehabilitation will continue to be anincreasing focus of most utility operatingbudgets and capital improvementprograms; especially as these systemscontinue to age. It is imperative that ourcustomers and rate payers understandthe importance of maintaining theseassets in terms of buried does nottranslate into forgotten – it cannot be outof sight, out of mind, or, in the end, asutility leaders, we will be going out ofour minds.Being a treatment guy, I often was notfocused on the collection and distributionside of the equation – it was simply anetwork of pipe that carried water (cleanor chunky) to and from the treatmentplant. The thought was that the treatmentplant was where all the critical equipmentand moving parts were; the infrastructurethat was most readily identifiable interms of asset management. But thatnetwork of underground infrastructure isan integral part of the overall treatmentsystem – without it, the treatment systemwould not be complete. Studying thehistory of water and sewer pipe revealedan interesting array of information andfactoids. We think of water conveyanceas a feat of modern science, but watercollection and distribution dates back toancient times. Over the span of history,these conveyance systems have takenthe form of wood, rock/stone, iron/steel,and plastic/fiberglass.Knowing how challengingexcavation can be, even with modernheavy equipment, provides a uniqueperspective on how this work waspreviously conducted. As I mentionedin my article in the winter edition, myfirst realization that people actuallyworked in the sewers came courtesyof the TV show The Honeymooner’swith Ed Norton – aka ‘The Sewerman’– and the beloved song of the sewer.Another critical aspect of buriedasset(s) management is maintenance.Preventative maintenance can extendthe useful life of pipeline, thus resulting insubstantive savings to a utility. The utilityprofessionals who work to maintain ourcollection and distribution systems aretruly the unsung heroes of our industry.One of the issues facing our industryis that of infrastructure needs and thesignificant shortfall in available funding.The days of government grants havelong since passed, and while mostutilities have excellent credit ratings toborrow money, there is only so muchdebt burden our customer base cansupport. The need to raise rates is alltoo often tempered by concerns ofpublic perception – it is not the politicallycorrect thing to do these days. Forgetthat average water/sewer bills are ofteneclipsed by orders of magnitude by“This issue of NC Currents focuses on thechallenges of the water industry in terms ofmanaging underground infrastructure or what isoften referred to as ‘buried assets.’”Click Hereto return to Table of Contentswww.ncsafewater.org 7

Large-scaLe DisinfectionThe new TrojanUVSigna . It’s ideal for those municipalitieswanting to upgrade their wastewater disinfection systemor convert from chlorine. The system provides high UVoutput, high electrical efficiency and the lowest lampcount (thanks to TrojanUV Solo Lamp Technology). It’salso easy to operate and maintain. Quartz sleeves areautomatically cleaned with ActiClean . Lamp replacementsare simple. And if you need to lift a bank from the channel,just activate the Automatic Raising Mechanism.Energy efficiency, fewer lamps and worry-free maintenance.That’s UV innovation. That’s TrojanUVSigna .Learn more at trojanuv.com/signa.

ETS UV SYSTEMS FROM CROCKER & ASSOCIATESFrom small scale package treatment plants to largemunicipalities Engineered Treatment Systems (ETS)can offer a range of ultraviolet (UV) disinfection/treatment solutions to suit any application.ETS ultraviolet (UV) equipment is designed andmanufactured in Beaver Dam, WI and utilizes manykey features such as 316L SS construction, UVmonitoring, variable power, temperature probes,drain ports, air vents, access hatches, Modbus/Profibus control connections, and a robust automaticquartz cleaning system that utilizes embedded pulsetechnology for a more reliable and effective cleaningsolution. In conjunction with their sister company,atg UV Technology, ETS has 35+ years in the designand manufacture of high quality closed vessel UVsystems.amalgam lamps, the 800W design allows for reducedcomponents while maintaining energy efficiency. Forexample one ETS 800W amalgam lamp will replace2.5 300W lamps. Furthermore in both designs, serviceand maintenance is made easy with ‘twist and lock’ UVlamps and a unique ‘sliding rail’ is built into the largersystem flanges, allowing for fast and easy access toboth the wiper system and quartz sleeves.The ETS UV systems come complete with eithera microprocessor SPECTRA control system, or anupgraded PLC control system. Both options feature;fully automatic start-up and shut-down, multiple lampmonitoring, process interlocks, HMI touch screeninterfaces, Modbus/Profibus communication and datalogging.CURRENT AND FUTURE NEED FOR UV: The useUV light has now become standard practice in mostmunicipal wastewater treatment processes. Effluent isnow starting to be recognized as a valuable resource,not an unwanted by product.STATE-OF-THE-ARTETS UV SYSTEMSDrinking Water : Wastewater : Water ReuseETS UV EQUIPMENT: Two key products have beendeveloped for use in the municipal markets. The SW/SX is an inline medium pressure closed vessel UVsystem. The design and lamp technology leads to avery small footprint requirement. The UVLW/UVLXdesign is the latest innovation from ETS. Thesereactors utilize 800W amalgam lamps which lead toan energy efficient UV system. With available spacein many facilities limited, the ultra compact designsand lamp technologies allow for both vertical andhorizontal installation directly into the pipe work.Like all choices, there are pros and cons to eitherdesign. However, both designs took into accountoperator maintenance and monitoring requirements.The SW/SX design has the fewest number ofconsumable components and utilizes constantwattage transformers (CWTs) to power lamps. CWTsare designed to operate for 20+ years where as mostelectronic ballasts need replacing every 1 to 5 years.The 800W UVLW/UVLX range of reactors is oneof the most powerful amalgam lamps used in theindustry. With similar efficiencies to traditionalMany wastewater facilities are being renamed as waterreclamation facilities, and whether the wastewater isbeing discharged into a river, being used to irrigatecrops, or injected into an aquifer for later recovery, UVis now being used to ensure water is free from harmfulorganisms.All the water that will ever be is, right now. (NationalGeographic) The world is quickly running out ofdrinking water. Critically the drivers are acceleratingpopulation growth, a warming climate, drought, urbansprawl, waste and excess. According to the WorldBank, water usage has increased by 600% since 1900,as the world’s population has increased by 200%.Water demand doubles every 21 years. The world’spopulation is forecast to increase again by 50% to9 billion people, causing 80 countries to face watershortages by 2050. Agricultural use of water accountsfor more than 70% of treated water use, and risingstandards of living will accelerate this trend. Thereforeit is logical to use reclaimed wastewater (“re-use”) forapplications such as crop irrigation.The era of “cheap” water is now drawing to a close,and price increases are inevitable to fund the repair orrehabilitation of aged infrastructure. Increasingly, waterconservation will become the norm, and wastewater,once seen as a nuisance to be discarded will be seenas a valuable resource. A non-chemical disinfectionprocess such as UV will play a key role as the planetrealizes how valuable clean water actually is.www.ets-uv.comTel: 920-885-46281131 Mount Gallant Road, Rock Hill, SC 29732Phone: 803.329.5384 / Fax: 803.366.2515www.crocker-associates.comKelley Wilber - Email: kelley.wilber@gmail.com / Tel: (704) 718-3099

Executive Director’s ReportLook for Jane Dubois at the AnnualConference – she will be behind thecamera, taking photographs of others inthe limelight – people receiving awards,Board members and committee chairs,visiting dignitaries. Or perhaps you willcatch a glimpse of Maggie Macomberputting out conference signs so that allof us can find our way. Maybe you willcome to a Young Professionals meetingand see Priya Sathyanaryan, MelindaKing or Mary Knosby inspiring awhole new generation to get involvedand participate. Or you might see BobFritts, Billy Allen, Greg Morgan, orAndy Brogden – they will be in thearea where Ops Challenge and PipeTapping will take place at the AnnualConference, moving mountains to getthe equipment and material necessaryfor the competition, giving hundreds ofhours each year to training people onthe rules and expectations, and moving theskill level to a new high. Or how about thestaff of our State agencies? You will findSteve Reid and Debbie Soles helping atevery school and conference, never in thelimelight, but always there to help ensurethat all goes well for attendees who needCEUs. And every year, there are morethan 150 vendors and consultants whobring the latest equipment into our exhibithalls, sponsor lunches and breaks to keepcosts down, and contribute equipment andexpertise to help us with technical training –they are hidden heroes too.When you see one of these hiddenassets, recognize that you are looking ata gem – a person of great value, and say“thank you.”Or perhaps you can help find and usean opportunity to educate a member of thepublic, or a civic group about water andwastewater and the enormous and essentialasset that it is for public health, for economicdevelopment, for quality of life.Please also think about helping a hiddenasset. By offering your help and by providingsupport, you can be the R & R – renewal byrelieving pressure, extending the resource ofthat asset, and becoming an asset yourself,when existing assets retire!We cannot afford to take hidden assets forgranted, so every one of you out there, doingyour jobs, thank you so much. You may beout of sight, but you are in my mind!Visitus onlinewww.ncsafewater.org12 NC Currents Summer 2011Click Hereto return to Table of Contents

Member PortraitPortrait ofTony DuBois:Managing Buried AssetsAs Zone 1 Manager for CharlotteMecklenburg Utilities (CMUD) FieldOperations Division, as well as theOfficer Responsible in Charge (ORC), TonyDuBois is responsible for more than 4,000miles of sanitary sewer collection lines,along with 4,000+ miles of water main thathe assists in managing. Says DuBois: “Ifyou laid end-to-end all the water and sewermains for which CMUD is responsible, thepipes would cover the distance from NorthCarolina to Juno Alaska and back. Basically,if there is a spill or break in the sanitarysewer collection system, I have to report tothe State and to the Federal EPA confirmingthe incident and that appropriate action wastaken” It is a challenge he is only too happyto embrace each and every day.With an ever-shrinking economy forcingmajor reductions in operating funds, workforceand budget challenges are greaterthan they have ever been. The CharlotteMecklenburg Utilities Department (CMUD)has already streamlined operations by combiningwater and sewer services and thendividing its service area into four zones, thusreducing travel time, improving customerservice and reducing fuel costs.But, the workforce has only continued toshrink, resulting in more responsibility beingplaced on every employee. As a result, theindustry has moved away from allowingmembers of its workforce to specialize in acertain skill. Today, employees are requiredby their new job descriptions to be multifunctioninggeneralists. It is impossible foranyone who is rotated out of an area everysix months to truly master a particular skillset, says DuBois.“If there is one aspect of my job thatI would want to change,” he continues,“it would be allowing employees to learn,grow, train and develop their craft inwhatever particular area they are needed.In an ever-depleting infrastructure, itis more essential than ever to havespecialized skills that allow you to stay intouch with your system rather than justputting a band-aid on it.”DuBois poses this question to industryleaders: “If you are sitting on an airplaneready to take off when a mechanical failureoccurs, would you want a generalist torepair your plane or would you want a specialist?When the most vital and preciousthing on earth is water, why would we settlefor anything less?”He adds that, as stress on the infrastructurecontinues to increase, it also becomesmore important than ever to prevent unnecessaryrepairs and maintenance. Part ofthat challenge involves engaging the publicin acting more responsibly.“Consumers do not understand that,by dumping grease down a sewer line orrunning food through the garbage disposal,they create huge problems within thesanitary sewer system,” says DuBois. Or,he adds, they plant trees over sewer lines,only to have the roots tap into the pipes andcause blockages.Part of the industry’s responsibility isto educate the public about what theyshould and should not do. DuBois points toseveral initiatives that are having an impact.One is the extensive AWWA programs thatallow people working in the industry to gointo elementary and junior high schools totalk about water and wastewater issues.Another is Charlotte’s Blue Planet ExhibitionHall, where young people can see thevoyage of a rain drop right through thedistribution system, to the collection andtreatment process, to the downstreamrivers. Charlotte also holds an annual WaterWeek during which the utility displays anddemonstrates equipment used in the treatmentof water and wastewater.Notes DuBois: “If there is something youwant the adults to do, start with the kids.28 NC Currents Summer 2011Click Hereto return to Table of Contents

For the public to conserve water or be verycognisant of what they are dumping downthe drain or commode, we need to promotethat at a young age.”At the same time, exposing young peopleto the field of water and wastewater is thefirst step in meeting another of the industry’sbig challenges: succession. Due to anever-growing level of attrition, utilities have anurgent need to pass on the knowledge of theold guard to a new generation. “We have aworkforce that is aging and retiring, but we donot have enough young people coming up,”says DuBois. “It is a challenge to find ways toconvince young people that this is an attractivecareer.”Providing opportunities for advancementis one way to encourage the next generationto become passionate about providingsafe drinking water and disposing of sanitarywaste. The key to those opportunities lies ineducation and training.DuBois certainly knows a thing or twoabout that. Shortly after obtaining hisGrade IV Collection Systems Licence in1992, he became involved in teaching atthe Distribution and Collection CertificationSchools. He remained with the committee forseveral years, eventually becoming a Grade ICoordinator.While still at Fayetteville’s Public WorksCommission (PWC), DuBois was awardedthe 1999 Collections Operator of the YearAward by the NC AWWA-WEA. Two yearslater, he left PWC to work as a private contractor,providing operations and maintenance(O&M) services on sewer systems forsmall townships. All the while, DuBois continuedteaching, eventually contributing at thenational level for the Professional EngineeringDevelopment program at the University ofWisconsin (U of W) in Madison. In 2004, aspart of an instructor cadre teaching everythingfrom biological chemicals to managingwastewater system, he delivered sanitarysewer collection courses at U of W’s threedaytraining school in Las Vegas, DuBoiscontinues to teach with the (U of W) instructorcadre throughout the United States.In 2003, DuBois joined the City of Charlotte,rising to his current position two yearslater. Since then, the Zone Manager hascontinued to be involved in education andtraining. From 2006 to 2008, he chaired theNC AWWA-WEA Distribution & CollectionSchool Committee, helping 3,000 operatorsgo through various stages of certifications.Then, from 2008 to 2009, he helped developthe charter for the new Wastewater Boardof Education and Examiners, (WBOEE), anadvisory group which provides test questionsand training curriculum to the NC WastewaterOperator Certification Board. Those sameyears, he was also awarded the GoldenManhole and inducted into the Select Societyof Sanitary Sludge Shovelers (5S).AD-CA-IRV-2011JAN24-P1V1Water andWastewater Solutionswith the Futurein Mind.DuBois credits all he has accomplishedto the loving support of his wife of 33 years.Actively involved with the NC AWWA-WEA,she has volunteered countless hours takingphotographs and running errands for theassociation. His wife even went as far astrademarking one of his favorite sayings.And why not? After all, when it comesto DuBois’ legendary commitment toexcellence, this says it all: SEWER CREW(All-The-Way) ® !Stantec delivers the following water and wastewatersolutions in North Carolina:• Master Planning• Water and Sewer Rehabilitation• Water and Wastewater Treatment• Collection and Distribution• Digester Gas to Energy• GIS, Surveying, and Subsurface Utility Engineering• Asset ManagementIn Charlotte, call Rob Stout at (980) 297-7656.One Team.

Member Portrait“The older generation in the industry has to continuebeing an example of what we like doing – which isbeing involved in the industry. By example, we canencourage younger people to participate and learn.”both long-standing members and thosenew to the water and wastewater sector,the association plays a vital role in passingthe torch to the next generation. “Theolder generation in the industry has tocontinue being an example of what welike doing – which is being involved in theindustry,” explains Willis. “By example,we can encourage younger people toparticipate and learn. An associationlike ours enables people to meet otherswith like interests and enables them toenhance their passion and learn.”Having an association that is nowstaffed provides members with the timeto partake in a multitude of activities, fromspeaking with high school students tomentoring those already in the profession.After all, encouraging new recruits involveseverything from sharing knowledge andexperience to ensuring a certain level ofexposure to the industry.Exposure can be as simple asanswering childrens’ questions about thewater towers they see on a family vacation.“Chuck’s son, who is now 15, could tellyou where the sewers went from the timehe was five years old,” notes Willis.Passing knowledge to the nextgeneration need not be complicatedeither. “I don’t assign a task orresponsibility to other people and thenget involved in doing it for them,” saysWillis. Instead he prefers to give peoplechallenges and provide a constructivecritique of performance.“We try to add to our team theoperating people who are going tooperate what we’re designing,” heexplains. “You can’t sit down in a roomand talk about a project or review aplan without exchanging ideas with theyounger generation involved in it. It hasto be a sharing process, not a dictatorialprocess.” In the end, he adds, it is allabout respect. By respecting one anotherand the ideas that each person – bothyoung and old – brings to the table,both generations can work together,successfully nurturing the vitality of thisindustry for generations to come.Click Hereto return to Table of Contentswww.ncsafewater.org 31

Special Section: Buried AssetsGuidelines for Use of Mini-Horizontal Directional Drillingfor Placement of HDPE Pipe, including Water ApplicationsBy Dr. Lawrence M. Slavin, Outside Plant Consulting Services, Inc.15 Lenape Avenue, Rockaway, NJ, 07866-1019, PH (973) 983-0813; FAX (973) 983-0813; email lslavin@ieee.orgIntroductionUser-friendly guidelines for the placementof high density polyethylene (HDPE) pipewith mini-horizontal directional drillingequipment have recently been developedby the Plastics Pipe Institute (PPI). TechnicalReport TR-46, Guidelines for Useof Mini-Horizontal Directional Drilling forPlacement of High Density PolyethylenePipe, represents a comprehensive set ofinformation that is directly applicable towater applications. The new document isintended to provide information analogousto that provided in ASTM F 1962,Figure 1 Typical Mini-HDD Equipment and Pilot Boring Process (Source: Outside Plant Consulting Services, Inc.Surface Drill Rig(Applies Thrust & Rotation,& Drilling Fluid)FluidSupplyWalk-OverReceiverAllowsTrackingStandard Guide for Use of Maxi-HorizontalDirectional Drilling for Placementof Polyethylene Pipe or Conduit UnderObstacles, Including River Crossings, butat a level appropriate for the less complexmini-HDD technology and typical projectcharacteristics.TR-46 reflects the latest industry information,but also includes new informationnot readily available elsewhere or in a convenientformat; this information is readilyavailable to the public via the website ofthe Plastics Pipe Institute at http://plasticpipe.org/pdf/tr-46-hdd-guidelines.pdf.Figures 1 and 2 illustrate typical minihorizontaldirectional drilling (mini-HDD)equipment and pilot boring and backreamingoperations, including placement(pullback) of the product pipe, such as forwater applications.Mini-horizontal directional drilling(mini-HDD) is typically employed for boringsegments less than 600 feet in length, atdepths up to 15 feet, and placing pipesup to 12 inches diameter. In contrast,maxi-HDD technology is capable of accuratelyboring holes thousands of feet inlength, and placing pipes of 48 inches orgreater at depths up to 200 ft. Maxi-HDDmachines may weigh as much as 30 tonsor greater, and are appropriate for placingpipes under large rivers or other majorobstacles.1 Drill Rod Length Straight in Ground2” x 10’ Steel(Semi-Rigid)Drill RodsTransmitter3” Drill HeadOriented Slanted DrillFace Allows Steering(Continuously Rotate toGo Straight)FluidAssistedDescriptionTechnical Report TR-46 contains 10main chapters or sections, as brieflydescribed below, supplemented by severalappendices.Figure 2 Typical Mini-HDD Back-Reaming and Pipe Pullback Process (Source: Outside Plant Consulting Services, Inc.)Surface Drill Rig(Applies Pullback & Rotation,& Drilling Fluid)FluidSupplyReamer/Compactor/SwivelFluidAssistedProduct Pipe(Water,...)Scope, Related Industry Standards andTerminology (Sections 1, 2 and 3)TR-46 addresses planning, design,drill rig setup, and installation practicesfor the placement of polyethylene pipeusing mini-HDD equipment. The primaryfocus is on commonly used high densitypolyethylene (HDPE) pipe with a materialdesignation code of either PE3608 orPE4710. Information is also providedfor pipe of medium density polyethylene(MDPE) PE2406/2708 material. Dependingon the diameter, polyethylene pipe may besupplied in continuous lengths on a reel ordiscrete segments, which would typicallybe fused together in the field. In addition towater supply applications, such pipe maybe used for conveying various other fluids(i.e., natural gas, oil), as well as conduitsfor containing utility cables.46 NC Currents Summer 2011Click Hereto return to Table of Contents

Preliminary Site Investigation(Section 4)The general feasibility of utilizing mini-HDD technology for placing the proposedpipeline(s) must be determined prior to anyproposed construction activities. Such apreliminary investigation is required to gainan understanding of the local characteristicsin order to help ensure a cost-effective,efficient and, above all, safe operation. Ofparticular importance, and as addressedin other sections of the guidelines, is theawareness of existing utilities in the vicinityof the proposed pipeline and the need tomaintain minimum specified clearancesduring the construction process.Safety and EnvironmentalConsiderations (Section 5)Safety is a primary concern during anyactivity, including construction utilizingmini-HDD equipment and procedures.Potential safety issues fall into two generalcategories: (1) those directly related tothe setup and operation of the mini-HDDequipment, and (2) those associated withthe proper location, identification andmarking procedures intended to avoidcontacting and damaging existing utilities.Section 5 of TR-46 addresses the firstcategory, providing practices to avoid orminimize equipment-related risks duringmini-HDD operations.drillrigone full rod lengthstraight in groundentryangleS1not to scale1entrypointS2d12d2near endaccess pitexit (bend)radius/curvatureRegulations and Damage Prevention(Section 6)Section 6 of TR-46 addresses the secondcategory of potential safety issues, focusingon procedures to eliminate or reducehazards associated with damaging existingutilities, including the timeframe during theinitial boring or back-reaming operations.Recommended practices include ‘callbefore-youdig’ (811), properly locating andmarking existing utilities, exposing suchutilities at anticipated crossings with thebore path, avoiding mechanized diggingwithin the required tolerance zone, and theuse of Subsurface Utility Engineering.Figure 3 Drill Rig Setup and Related Distances (Source: Outside Plant Consulting Services, Inc.)d33S5far endaccess pitd44straight segmentexit angleS4exit (bend)radius/curvature3S3exitangleClick Hereto return to Table of Contentswww.ncsafewater.org 47

Special Section: Buried AssetsAre You Really Getting to Know What’s Below?Strategic asset management capabilities, coupled with powerful data andforecasting can help utilities plan, manage and focus on a successful future.By Rosemary Harman, Erick Hancock, and Hatem El-Sayegh-JacobsUtility managers are in a bind. They mustprovide their customers with the same levelof service they have historically enjoyed,but thanks to declining revenue and shrinkingbudgets, they have less money andfewer resources to accomplish that. Onesolution is to achieve maximum life cyclefrom current infrastructure assets. Theseassets are expensive, and replacing themis no small matter. However, how do theyknow when the asset has reached the endof its life, what should its replacement be,and how will the replacement be funded?These questions can be answered bytaking an efficient and planned approach to‘knowing what’s below.’ This approach hasthree primary components:1. capturing vital data on all assetsand determining how assets will bemanaged;2. streamlining review of conditionassessment data and identifyingneeds for appropriate asset rehab andreplacement; and3. establishing budget plans andcomprehensive asset managementprocedures.Capturing DataProperly utilizing any asset one knows littleto nothing about is next to impossible.Imagine attempting to assess the value ofa tool without knowing where it is, whatit’s doing, how it’s performing or how it’sholding up over time. Finding out all onecan about a particular asset versus makinggeneral estimates and assumptions aboutasset stability and performance will mitigatecostly and time-consuming efforts.The first step is to take stock of whatyou are doing well and then determinewhere improvements are warranted. Currently,there is a ground swell of interestsurrounding asset management (AM). It isnot difficult to see why when even smallsystems are responsible for maintainingtens of millions of dollars of assets. As utilitiesand managers initially become involvedin AM they find they must answer the followingquestions:• What do I own?• Where is it?• What is its condition?• What is its useful life?• What is its value?• Is it adequate for my needs?As an organization tries to answer the sixbasic asset management questions suggestedby the US Environmental ProtectionAgency, it is quickly apparent that managementand organization of this informationwill be a formidable task.It is easy to see the need to identifyparticular assets and their location, and thedata necessary to answer those questionsis fairly straightforward. However, whenyou consider the volume of informationrequired to assess condition, estimateremaining useful life, appraise value, anddetermine if the asset is still adequate foryour needs, the data requirements canbecome overwhelming. Prior to any datacollection effort, owners must make decisionson what information has significanceto the organization now, and here is thetricky part, what may be important in thefuture. Predictive models will aid a utilityin projecting future Capital ImprovementProgram (CIP) needs. These models, however,require calibration with utility specificdata that typically is either not availableor not readily accessible. The usefulnessand accuracy of these models improvessignificantly as the quality and quantity ofdata improves. How to acquire this dataeconomically becomes the question.A frequently overlooked opportunity tocapture valuable data occurs in the courseof routine field activities. Utility crews areoften able to collect information on systemassets during the performance of theirduties. With a little planning and a modestinvestment in data collection equipment,critical attributes can be acquired withnegligible impact to crew schedules. Forexample, during right of way maintenance,a crew equipped with a handheld devicewould need only a minimal amount of extratime to take a digital photo of the assetand collect the GPS coordinates.

position of pipes, and material of constructioncould also be gathered and keyed intoa template loaded on this device. Collectinginformation in this manner is much lessexpensive than sub-contracting this effortto a third party. Even if you do not collectall the data and end up using the servicesof a third party, a partial database providesa good starting point and reduces theoverall effort.How well are youMaintaining your Assets?Taking a ‘break and fix’ approach to themaintenance regimen is increasingly findingdisfavor with regulators and utility decisionmakers. A reactive maintenance approachhas given way to more advanced maintenanceapproaches up to and includingpredictive maintenance technologies. Itis common for facility managers to facepointed questions when requesting fundsto repair or replace costly equipment, particularlyif that equipment has not reachedthe end of its expected life cycle. Beingable to provide evidence of proper maintenancethrough a documented, detailed,maintenance history has become theexpectation. For many utilities, the answeris a Computerized Maintenance ManagementSystem.As data is being collected and work isbeing completed, the need for a system tomanage this information becomes quicklyapparent. A Computerized MaintenanceManagement System (CMMS) is the logicaltool to accomplish this task. Additionally,a CMMS serves as a logical entry pointfor many utilities into AM, and ultimatelyprovides the foundation for a robustprogram. In its basic form, a CMMS is ahardware/software solution to streamlinemaintenance operations. With over 2000CMMS programs currently on the market,choosing one can be daunting. Too often,people get caught up in the look and feeland do not focus on functionality and findingthe best match for the job at hand. Anexperienced consultant can be a valuableresource to help develop a short list ofcandidates as well as assist in addressingfuture and immediate needs.A CMMS should provide an intuitiveinterface and should:• contain asset registry/hierarchy;• include a defined naming convention;Figure 1 Asset-RAT can run in a GIS environment or as a stand-alone process• record and maintain work history;• include work tasks and frequencies;• maintain maintenance inventory; and• accommodate all methods of workaccomplishment.Careful consideration should be given towhat information is required from a CMMSto avoid a potentially costly mistake. Ifthere is a desire for information from alegacy software application to be incorporatedduring a CMMS implementation,the data structure and availability shouldbe investigated prior to selecting a CMMSprogram. The software vendor should providea detailed explanation of how this willbe accomplished and how the interfaceswill be maintained.Top-level support and communicationplay critical roles in the successful adoptionof a CMMS. Often, employees will placevalue on what you value, and if a CMMS issupported from the top down and its importanceis communicated throughout theorganization, its value will become evidentto all involved. Conversely, if employeesperceive this as the latest ‘flavor of themonth,’ and they do not see the value, itis most likely doomed to fail. It is also veryimportant to communicate that a CMMS isa tool and an explanation of how it is goingto improve the way work is performedshould be provided. One recommendationis to use a staged approach to CMMSimplementation, as many organizations findthe prospect of an all or nothing implementationapproach daunting. By starting smalland building on experience gained duringa phased approach, a utility need not fearan implementation reaching beyond theircapabilities or resources.Streamlining Review of DataWith the substantial increase in the numberof sewer rehabilitation methodologiesavailable, and the significant improvementsin condition assessment technologies andprocedures, utilities may find themselvesfaced with a potentially complex processwhen deciding which rehabilitation methodto use for which pipe. A utility-specific decisionsupport methodology can be a valuabletime saving tool in such cases. Manylabor hours can be saved by streamliningthe condition assessment data review andrehabilitation decision process.As one might understand, a manholeand pipeline condition assessmentprogram performed by a utility cangenerate an enormous database, includingthousands of records and hundreds ofattributes. It can be a daunting task toreview this amount of data in order tomake decisions about the most feasiblerehabilitation solutions.

photos, and private property inspections.Condition data and rehabilitation approachwas reviewed for over 1,000 pipesegments and over 800 manholes. Theautomated version of Asset-RAT wasimplemented based on utility-defined rules,and a rehabilitation specialist then usedthe QC module to review the rehabilitationrecommendation. The review resulted inlowering the rehabilitation cost with smalleffort, since data for all pipe segmentshas been run and checked through theautomated process. The QC moduleallowed the rehabilitation specialist to focusonly on the pipe segments that matchedprioritization criteria defined by the utility,rather than reviewing the entire database.Where some utilities may havetraditionally favored a specific rehabilitationmethodology, the ability to perform atimely comparison and analysis using theapproach discussed here can save theutility valuable resources and money. It alsoprovides decision makers with useful tools,including GIS maps and Crystal ® reports,to make informed decisions with minimaluncertainties.Once the implementation of the Asset-RAT is completed and the projects havebeen reviewed, the projects are readyfor processing through procurement andbidding. In cases where the utility choosesto perform the rehabilitation work in-house,the recommendations can be retrievedfrom the database and executed accordingto their priority and available funding.Figure 3 The project tracking database at Mount Pleasant Waterworks is integrated withthe financial system and rate model, allowing commissioners to view how changes to largecapital projects will affect long-term budgets and ratesEstablishing Budget PlansHaving already identified priority areas forrehab and replacement, the next step isplanning and prioritizing the CIP budgetand managing each project. For thiseffort, Jacobs developed a proprietary toolcurrently in use at several utilities that hasproven to be invaluable in accomplishingthese tasks by increasing accessibility toinformation, storing and reporting on themany details crucial to each project, andproviding information needed for budgetingand financial forecasting.A flexible information system that isindividually configured in each applicationwas developed. Built-in customizationtools allow each system administrator toeasily make changes as business practicesevolve and change, ensuring the systemwill provide long term value and return oninvestment.Project TrackingSeveral utilities in the Carolinas, includingMount Pleasant Waterworks (MPW) andBeaufort-Jasper Water and Sewer Authority(BJWAS), are using unique versions ofthis modular system for project trackingand capital planning.

Special Section: Buried Assetsinformation anywhere they have an internetconnection. Some of the functions of thesesystems include:• tracking and reporting on projectbudgets, cost estimates, and cash flowprojections;• recording the bidding and constructioncontract award process;• monitoring project schedules;• tracking permits and related regulatoryrequirements;• logging of consulting engineers andcontractors on the project, includingtheir contact information, and allagreements and invoices;• recording easement acquisition andutility relocation activities;• providing document storage forproject records, documents andcorrespondence, as well as projectmanager comment logs;• serving as a communication toolby automatically generating presetmessages and reminders; and• providing reliable financial informationfor long-term CIP planning.CIP PlanningBy integrating the information storedin the project tracking database withfinancial systems, decision makershave a powerful project-centric financialforecasting tool. Customized interfaceshave been developed that export the CIPbudget from the project tracking systemdirectly into the rate model. This keepsthe CIP and rate model in balance andallows changes made to individual projectbudgets to cascade through financialsummaries and rate projections.Using built in flexible fiscal escalationvalues enable the system to producefinancial plans looking forward 20 years(Figure 4). At MPW commission meetings,each board member now has a laptop,with simultaneous screens showing howchanges made to individual projects willaffect the long term budget and rates.

Systems such as these areenthusiastically accepted, since they arecustomized to the workflow and terminologyusers are accustomed to seeing.For each of these utilities, the use ofthese systems has expanded over timeincreasing their overall value. As opposedto ‘out of the box’ software that can belimiting and expensive to maintain, asystem built on open architecture thatcan be easily customized will pay for itselfmany times over. Since implementing theirsystems and becoming less dependent onpaper copies and reports, several utilitieshave found they require less staff and savethousands per month in manpower andsupplies that were devoted to printingdocuments. The savings in better decisionmaking, budgeting and planning areharder to measure, but are even greater.As utility managers continue toaddress customer service demands withfewer personnel and tighter budgets,the importance of achieving maximumlife cycle from current infrastructureassets becomes a critical part of the54 NC Currents Summer 2011Click Hereto return to Table of Contents

comprehensive management process.But, without properly leveraging dataand asset intelligence, utility managerswill continue to fall short in truly ‘knowingwhat is below.’ The power of assetinformation is immense, but, unless thatpower and data are properly assembledand analyzed to facilitate the longtermdecision making process, the truepotential of the utility will be in jeopardy ofbeing lost underground.About the authorsRosemary Harman, GISP, PerformanceUnit Manager, Management Consulting– Jacobs has worked for the past 10 yearstailoring IT and GIS technical solutionsto the water industry.

Special Section: Buried AssetsLeveraging GIS to Assign Sewer Pipe CriticalitySaves Time and Effort and Assists with Capital PlanningBy Celine Hyer Malcolm Pirnie Water Division of ARCADISIntroductionLee County Utilities is located in Ft.Myers, Florida and serves approximately300,000 customers. The system has 875miles of sewer line and 1300 miles ofdistribution lines.Lee County Utilities (LCU) beganimplementing an asset managementprogram in November of 2008 to improvethe management of their assets, shortandlong-term renewal and replacementplanning, and staff efficiencies.Implementing a comprehensive assetmanagement program with the traditionalplanning, design, and implementationphases can typically take three tofive years and cost millions of dollars.LCU was determined to implement acomprehensive asset managementprogram to improve the managementof their more than $700 million dollarsworth of assets, but did not want to waitover three years to see any meaningfulresults, and wanted to minimize the costsas much as possible. Because of this,Malcolm Pirnie and LCU formulated a fasttrack approach that would complete theplanning and design of the program inless than a year, would focus solely on asmall portion of the system – WaterwayEstates, and would fully evaluatethe small pilot area in terms of assetcondition, criticality, risk, renewal andreplacement funding, and potential rateimpacts.Workshops were held with LCU staffto establish an asset hierarchy anddefinitions, methodologies for condition,criticality, risk, useful life and replacementcost estimating for undergroundand aboveground assets. In addition,an assessment of the current IT systemsused for work management wascompleted as well as an organizationalassessment in relationship to implementingan asset management program.Field assessments in Waterway Estatesincluded visual condition assessmentsfor the aboveground assets, zoomcamera inspections for gravity pipes andmanholes, and a pipe reliability study forpressure pipe condition. A consistentmethodology and scoring was establishedfor asset criticality of pipe assetsincluding water, sewer and reclaimedwater pipes during the pilot and then appliedto LCU’s full system.DiscussionAsset Management BasicsAsset Management is based uponmanaging the risks associated withasset failures to meet defined levels ofservice in the most cost effective manner.To understand asset risk, the assetprobability of failure and consequenceof failure is evaluated. For LCU, theprobability of failure was defined as theasset overall condition and evaluatedboth the current state of repair andperformance capabilities of the asset.Figure 1 – Risk MatrixEvaluating these two components forasset condition is very important becausean asset can have other failure modesbesides mortality or physical condition.The following equation was used torepresent overall asset condition:Physical Condition + PerformanceCondition = Overall Asset ConditionThe current state of repair of theassets, or asset physical conditioncriteria was based on the NationalAssociation of Sewer Service Companies(NASSCO) for pipe assets both on a 1to 5 scoring scale where 1 is excellentcondition and 5 is very poor. Theperformance condition of the assets wasevaluated for the other failure modesincluding capacity, reliability and, O&Missues on a similar 1 to 5 scale.Asset criticality or the consequence offailure for the assets was defined by a 1 to60 NC Currents Summer 2011Click Hereto return to Table of Contents

3 scoring scale based on the effect of assetfailures on the categories of financial,social and environmental impacts. SpecificGeographic Information System (GIS)queries were created to evaluate theseimpacts based on adjacency characteristicsand pipe attributes.Asset risk was defined by combiningthe overall condition or probability offailure, and the criticality or consequenceof failure as shown in the followingequation. Risk can also be graphicallyrepresented, as shown in Figure 1, todetermine the appropriate relative priorityor capital planning periods for an asset.Asset Risk = (Physical Condition +Performance Condition) * CriticalityCriticality Methodologies SpecificsTo evaluate pipe criticality, the existingWater Research Centre (WRc) standardsfor sewer pipes were applied andcustomized to represent all pipe typesfor the LCU system. The customizationaddressed LCU’s local environmental andoperating conditions, adopted a numericscoring system instead of letters, andconsidered the current availability of GISdata for sewer, water, and reclaimedwater pipes. In this case, LCU has spentsignificant time and effort in maintainingand updating their GIS data and almostall pipe segments were assigned age,diameter, material and depth attributes.The categories and evaluation criteriainclude the following:• Physical Criteria: - Cost Impact toRepair• Size, Depth, Ground Conditions(pavement, grass etc)• Performance Criteria: - Impact toCustomers/Environment• Number of customers served(largest users)• Regulatory non-compliance,environmental impact, publicimage• Adjacency Criteria: - Social /Economic Impacts• Type of road (heavy traffic,moderate traffic, etc.)• Under buildings, canals, railways,etc.• Adjacent to business districts,tourist areas, etc.LCU developed specific evaluations for eachtype of linear asset and for each criterion togroup the assets as follows:• Class A: high criticality – score = 3• Class B: moderate criticality – score = 2• Class C: low criticality – score = 1The criteria are automatic rather thanweighted and the higher score governs.Therefore, a pipe asset, such as a sewerforce main, which meets any of the criteriafor Class A and some of the Class B criteria,would receive an overall criticality score of3. An example of the standard WRc gravitysewer criteria for selecting the most criticalpipes and the LCU modified criticalityscoring criteria is demonstrated as follows.WRc criteria formost critical gravity sewers:Automatic ‘Class A’ gravity sewers• Brick Sewer 6-ft or deeper• Sewers 18-ft or deeper• Sewers 15-ft or deeper in ‘bad ground’• Sewers larger than 24-inches• Sewers in a ‘highly important’ road(7,500 vehicles/day)• Sewers where failure disrupts hospitaltraffic• Sewers under buildings, railways,canals, rivers, highways• Sewers in main shopping areas• Sewers within access ways to industrialsitesTable 1 – Gravity Pipe CriticalityTable 1 - Gravity Sewer Criticality Criteria and ScoringClass A Criteria*All ductile iron pipesSewers greater than 18 inches in diameterSewers greater than 12 feet deepMain feed lines to wastewater treatment plantsSewers under buildings, railways, and water bodiesSewers in tourist areasSewers in high traffic roads designated as arterialClass B Criteria*Sewers 10 to 12 feet deepAll pipe greater than 12 inches and less than 18 inches indiameterSewers adjacent to waterways – designatedenvironmentally sensitive areasSewers in area difficult to access for repairs (back yardeasements) – greater than 100 ft from centerlineLCU established criteria for mostcritical gravity sewers:Automatic Class A or score of 3 gravitysewers• LCU established criteria for mostcritical sewers• All ductile iron pipes• All pipes greater than 18 inches indiameter• Main feed lines to WWTPs• Sewers greater than 12 feet deep• Sewers located in tourist areas• Sewers in a highly important road(7,500 vehicles/day)• Sewers under buildings, railways,canals, rivers, highwaysThe evaluation criteria for each type ofpipe asset are presented in Tables 1through 4.The criteria shown in the tableswas applied through a GIS analysisand produced color-coded mapsrepresenting the pipe criticality of scores1, 2 or 3. By viewing the maps, staffwas able to quickly perform a realitycheck to determine if the customizedcriteria made sense or if too many pipesas were being designed as ‘the mostcritical.’ An example of the percentagesfor the gravity mains is shown in Table5. Some minor changes were made tothe criteria after the first iteration of theprocess to refine the queries, especiallyAutomatic ScoreAssets meeting anyClass A criteria:Score =3Automatic ScoreAssets meeting anyClass B criteria:Score =2* High score governs.

Aerial photo overlayswere also used to help verify theappropriate distance to use for someof the adjacency criteria. A samplecolor-coded map for the gravity mainsis also shown in Figure 2.Data Results and UsageThe methodology established forthe criticality analysis for WaterwayEstates pilot was fairly simple to applyand quickly evaluated all pipe andplant assets on a consistent scale of1 to 3. The results were discussed inworkshops with LCU and staff agreedthat the study matched their gut feelfor what was important in their pipesystems. The next step involvedapplying the established criteria to thefull utility system using the establishedqueries.The criticality ratings can be usedto guide the frequency of conditioninspections, preventative maintenanceactivities, and to prioritize replacementprojects. LCU is in the processof implementing a computerizedmaintenance management systemwhere these activities will bescheduled accordingly. Whencombined with condition scores, thedata can also be used for short- andlong-term capital planning. The overallrisk score ranges and/or location onthe risk matrix, as shown on Figure1, supports this planning effort. Anexample from the pilot program ofusing the criticality data to quicklyprioritize pipe repair or replacement isshown in Table 6, where assets withsimilar remaining useful life can beeasily differentiated by criticalityAgain, this data is currently beingused for renewal and replacement aswell as operations and maintenanceplanning, and will be used in the futureto determine the priority for conditionassessments. By starting with anexisting standard, it was a fairly simpleprocess to evaluate all pipes on aconsistent scoring basis. By keepingthe scoring a simple 1-3 (representedby blue, orange and red on the map)rating shown in Figure 2, the GISqueries and analysis were also simple62 NC Currents Summer 2011Click Hereto return to Table of Contents

Special Section: Buried AssetsUsing CMOM to Optimize Utility OperationsBy Chris Browning, Utility Management Director, McKim & CreedThrough the development of good regulatorypolicy and the advancement of technologyover the past 40 years, utilities havemade significant improvements in the ecologicalbalance of the waterways throughoutthe United States. However, we are onthe brink of another environmental crisis.The focus has been primarily on water andwastewater treatment issues and not on thepipes. As a result, the infrastructure ‘outsidethe fence’ has aged and deteriorated tothe point where it no longer performs asintended.There is a bright side to this potentiallydismal reality. Through the diligence of theEnvironmental Protection Agency (EPA) andwith input from various utility members, aprogram was developed several years agoto curtail the impacts of failing infrastructure;this program is known as CMOM (CapacityManagement Operations and Maintenance).Even though it was never promulgated, itestablished Best Management Practices(BMP) for collection systems to ensurecapacity for growth, and identified practicaloperation and maintenance guidelines.CMOM as Proactive Planning ToolSanitary sewer overflows (SSOs) are illegalunder the Clean Water Act, but EPA estimatesthat there are at least 23,000-75,000occurrences each year in the US. TheCMOM program identifies critical elementsthat focus on preventing or reducing thelikelihood of SSOs. In addition, CMOMoffers guidelines for maintaining intendedsystem performance, extending the lifeof sewer system components, improvingcustomer satisfaction, protecting treatmentfacilities/pumping stations from harmful elements,enhancing public health and safety,and protecting the environment.CMOM can be applied to all types ofsystems, and is a proactive planning toolthat can help utilities provide a high level ofcustomer service while reducing instancesof regulatory non-compliance.The primary elements of CMOM include:• Emergency Response/Mitigation Plan• Inspection/Cleaning Program• Mapping and Inventory• Hydraulic Model• Maintenance Management System• Grease/Roots Management Program• Capacity Certification Program• Operations and Maintenance TrainingProgram• Repair and Replacement ProgramEmergency Response/Mitigation PlanThe law requires wastewater collectionsystem owners/operators to construct,operate, and maintain their systems in amanner to avoid SSOs. However, we allknow that standard is somewhat difficult.Therefore, until we are all able to meetthat goal, a comprehensive response andmitigation plan is an integral part of CMOM.A well-developed and executed plan canalso significantly minimize the impact on theenvironment and public health.States have varying requirements forreporting SSOs, however, all plans shouldfocus first on response and mitigation. Theemergency response/mitigation plan shouldinclude the following procedures:• immediate personnel and equipmentdispatch to mitigate the problem;• public access limitation/control;Sanitary sewer overflows (SSOs) can negatively impactpublic health, water quality, and the environment.According to the 2008 EPA Clean Water Survey, thecost to repair the collection systems in the UnitedStates exceeds $83 billion.66 NC Currents Summer 2011Click Hereto return to Table of Contents

• cleaning and disinfecting the affectedarea to minimize the public healthimpact;• notifying the general public, downstreamwater providers, and regulatoryagencies;• volume estimation;• cause evaluation and remediation,including aeration schedules for SSOsentering impoundments;• corrective action to minimize thelikelihood of future occurrences; and• monitoring and sampling impactedwaters to ensure proper ecosystemrecovery.In addition to the development of theprocedures listed above, a comprehensive,ongoing training program should bedeveloped and implemented to enable allresponders to execute their assigned dutiesefficiently and expeditiously the goal is toensure minimum environmental and publichealth impacts.Inspection/Cleaning (I/C) ProgramIn past years, utilities periodically cleaned100% of their collection systems andinspected a representative sample. Thatpractice should be reversed. About 70% ofthe system does not require cleaning, but100% of the system should be inspected toidentify and quantify defects. The inspectioninterval should be once every five to tenyears, dependent on the system age, size,and material.A standard defect coding system shouldbe used to ensure all data is consistent. TheNational Association of Sewer Service Companies(NASSCO) has developed standardsfor pipe and manhole inspections. Theirstandard coding and ranking systems—Manhole Assessment and CertificationProgram (MACP), and Pipeline Assessmentand Certification Program (PACP)—usevisual assessment of manholes and videopipe inspection to objectively prioritizemaintenance or repair/replacement requirements.In addition to identifying obviousdefects needing immediate attention, utilitystaff can use PACP (coupled with varioussoftware systems) to qualify and quantifydefects, help avoid potential catastrophicfailure, and assist in Capital ImprovementPlan (CIP) development.As part of CMOM, the program shouldbe structured to provide staff and equipmentto enable the following: 1) dedicatedroutine activities without interruption, and2) emergency responses to mitigate SSOs,and 3) preventative maintenance activities.To ensure the system is inspected andcleaned within the desired interval, theroutine activities should be dedicated sostaff and equipment can meet the requiredproduction rates. Dedicated crews cancomplete about 300,000 feet annually.Standard procedures are necessary to enableemergency responders to minimize theimpact of an SSO and ensure the problemhas been properly mitigated. In addition,upstream and downstream I/C should beexecuted after every SSO.Every system has areas where greaseand debris collect, creating a potential SSO.To avoid overflows, a preventive maintenanceprogram should be developed toinspect and clean those areas in shorterintervals (i.e., quarterly, semi-annually, orannually).In addition to the physical inspectionof the manholes and pipelines, smoke/dye testing and right-of-way (ROW)/easementinspections should be included in theprogram. Smoke testing will identify sourcesof inflow and infiltration (I&I) into the sewermain, illegal connections, and buried manholes.ROW and easement inspections willhelp identify potential system failures andmissing or damaged manhole lids.Mapping and InventoryThe foundation of a successful CMOM programis a comprehensive system map. Themap should include highly accurate verticaland horizontal data for each manhole andthe related attributes, including the follow-EPA estimates that there are at least 23,000-75,000 SSOs each year in the US.EPA estimates that a $390-billion investment in wastewaterinfrastructure is needed over the next 20 years,according to ASCE’s 2010 Report Card for America’sInfrastructure.

Special Section: Buried Assetsing: 1) pipe size, material, condition, age,and slope; 2) manhole diameter, condition,depth, material, enter/exit pipe size, andflow direction; and 3) pump station location,capacity, number/type of pumps, condition,level alarm type and backup power availability/type.In addition to fulfilling operational,maintenance, engineering and managementneeds, this information is essential forthe development of a dynamic collectionsystem model.Generally, 5-10% of manholes are buriedor covered by pavement. To effectivelyexecute the mapping and inventory project,consideration should be given to implementingthe I/C program prior to initiatingthe mapping and inventory project. The I/Cprocess will locate hidden manholes so theycan be raised and made accessible for themapping and inventory process.Although the mapping and inventorycan be compiled on paper maps and files,utility owners should consider electronicGIS-based mapping and inventory systems.With electronic data systems, additions ormodifications to the collection system canbe easily captured, and modifications to thebase map can be made accordingly. Theprocess is ongoing, and system modificationsor additions should be made in atimely manner to enable access to maintainaccurate information.To enable staff to better understand theirsystem and easily retrieve the informationfor operational, maintenance or managementpurposes, the maps and relatedattribute information must be accurate. Newdata and attributes need to be capturedand entered into the system in a timelymanner; therefore, data standards must bedeveloped and adopted for new constructionand repair/replacement activities. In addition,to avoid corruption of the base map,proper quality control measures should bein place.Hydraulic ModelA computerized dynamic hydraulic modelis an essential tool for the developmentof a capacity management program andthe prioritization of the CIP. After data iscaptured in the mapping and inventoryphase of the program, a hydraulic modelcan be developed and used as a tool todetermine available sewer system capacity,evaluate the impact of proposed developmentprojects or forecasted growth,identify deficiencies during rainfall events,and project impacts related to proposedsystem improvements.The development of a dynamic modelis contingent upon the high-resolution dataand related attributes gathered during themapping and inventory phase, along withdry/wet weather system flow and rainfalldata. To develop realistic, manageablescenarios, the model should include wetweather assumptions for maximum systempeaks related to I&I during various rainfallevents. The peak flow assumptions willprovide the limits to enable the model tocalculate the amount of I&I that can be effectivelymanaged at the treatment/pumpingfacilities, and to determine the relative upgraderequirements of the collection systemto avoid SSOs.Maintenance Management SystemThe general focus of collection systemmaintenance is to ensure the intendedhydraulic capacity, function, and reliability ofboth the gravity and pressurized systems.An effective maintenance managementprogram is essential for proactive utilitymanagement, and will reduce the likelihoodof mechanical failure and reduced pipecapacity related to obstructions or defectswithin the system.Preventive and predictive maintenancecosts are generally 25-30% lower thanreactive maintenance costs. In addition,planned maintenance is less likely to impactcustomers and sends a positive message torate payers, elected officials and regulatoryagencies.An effective maintenance managementsystem should include:• asset information and relatedmaintenance requirements;• standard operating/maintenanceprocedures;• preventive/predictive maintenanceschedules for mechanical systems,pipelines and rights-of-way/easements;and• maintenance activity tracking/historicalinformation system.A maintenance management system canbe manual or computerized, however, eventhough a well-developed manual systemcan meet needs, a computerized systemenables more diversity and flexibility whenmanaging complex systems. The ComputerizedMaintenance Management System(CMMS) can provide quick access to rela-If capital investment and O&M spending forwastewater infrastructure remain at currentlevels, EPA estimates a funding gap of approximately$270 billion 2000–2019.

Special Section: Buried AssetsLarge-Diameter Parallel Sewer in an Urbanized SettingRequires Precise Above-Ground and Subsurface Utility EngineeringBy Chris Windley, PE, Water Engineering Project Manager, McKim & Creed; andSean Patterson, CST-IV, Subsurface Utility Engineering Project Manager, McKim & CreedThe City of Raleigh Public Utilities Department(CORPUD) provides municipal wastewaterservice to approximately 156,000metered customers and a service populationof approximately 485,000. The City hasmerged its water and wastewater utilitieswith surrounding communities, includingWake Forest, Garner, Rolesville, Knightdale,Zebulon and Wendell, by taking ownershipof their systems. These utility mergers areintended to consolidate these systems andultimately decrease the customers’ utilityrates for water and sewer service.With the mergers, the City’s servicearea covers 270 square miles and extendsinto three major drainage basins: Crabtree,Neuse, and Walnut. The City’s overallwastewater system includes three wastewatertreatment facilities. The largest is theNeuse River Wastewater Treatment Facility(WWTF) located in the southeast region ofWake County near the confluence of theNeuse River and Poplar Creek. The facilityis currently permitted to treat 60 MGD ofwastewater, and the City is now in the firstof five expansion phases to increase thepermitting capacity by 15 MGD.Approximately 20 MGD of the City’saverage daily flow to the facility comesfrom wastewater collected in the CrabtreeBasin. The major wastewater infrastructurewithin the Crabtree Basin includes parallelgravity sewer interceptors along CrabtreeCreek that range in size up to 66 inches indiameter. Dual 60-inch gravity interceptorsdischarge into the Crabtree Wastewater LiftStation (LS) located at the interchange ofI-440 with the US 64/264 Bypass on theeastern side of Raleigh.Addressing I&I and SSO ChallengesThe City has been faced with inflow andinfiltration (I/I) challenges in many of its aginggravity sewer systems that collect and conveyflow to the Crabtree Basin interceptors.Design is now being finalized for rehabilitationof the North Bank Interceptor, whichtraverses the north side of Crabtree Creek.The City is still faced with the critical needto increase wet-weather capacity alongthis interceptor system. The Crabtree Basinwet-weather flows were estimated to be 56MGD in 2006, according to the City’s SanitarySewer Capacity Study (SSCS) completedin 2008. With a 19.9-MGD estimateddry-weather average daily flow in 2006, thebasin system was experiencing an averagepeaking factor of 3.26. The I/I conditionsand associated excessive wet-weatherpeak flows have resulted in sanitary seweroverflows (SSOs) in the Crabtree Basin.The selected alternative from the SSCSand the other ‘high-altitude’ evaluationswas construction of a 20-MGD wastewaterpump station with a 4-MG equalizationbasin and 52,000 LF of 42-inch force main.This alternative was estimated to be themost economical approach for solvingthe City’s infrastructure problems in theCrabtree Basin.The project, known as the CrabtreeBasin Pump Station and Force Main, wasA portion of the route for the new gravity interceptor will be located along this greenway at Lassiter Mill Park.70 NC Currents Summer 2011Click Hereto return to Table of Contents

included in the City’s FY 2008-2009 CapitalImprovement Plan (CIP), which covered proposedimprovements through 2030. It wasestimated to cost $60-70 million of the total$850 million for the wastewater improvementprojects in the CIP.Re-Evaluating the Original SolutionIn 2009, the engineering team of Hazenand Sawyer, PC and McKim & Creed wasselected by the City of Raleigh to perform adetailed preliminary engineering report (PER)and environmental assessment (EA) for theproposed pump station and force mainproject. Very early in the PER development,it was apparent that a force main routealong the existing interceptor corridor was alikely alternative for a number of reasons. Aspart of the PER, CORPUD project managerAaron Brower, PE, asked the team to alsoevaluate an alternative that would extendthe gravity sewer from Glenwood Avenueon the north side of I-440 to the existingCrabtree Creek LS at the I-440 interchangewith the US 64/264 Bypass. Brower, whois now the Public Utilities Department’sCity Construction Projects Administrator,explained to the team that while heunderstood the previous recommendationfor a pump-around option with an upstreampump station and equalization basin, herecommended evaluating the gravity seweroption in more detail before implementing afinal design.The Public Utilities Department generallyseeks solutions in which gravity sewercan be installed or extended to avoid oreliminate pump stations. In this case,the concern involved the reality of havinga wet-weather pump station that mayoperate only a handful of times during oneyear, resulting in significant challenges formaintaining the equalization basin andpump station. The pump station would alsohave to be located in an area surroundedby existing residential and commercialdevelopment.The results of the team’s PER indicatedthat whether the City extended a forcemain or gravity interceptor along theproject area, the recommended routewould be along the existing gravityinterceptor corridor paralleling CrabtreeCreek. This route allowed either pipe lineto avoid higher ground elevations, thusreducing static head for the force main orinstallation depths for the gravity sewer.The majority of the route is City-ownedproperty designated for public parks and/or greenway trails, which would significantlyreduce the impact to private land ownersand minimize land acquisition costs.The engineering team evaluated multiplealternatives for the gravity sewer option thatincluded diverting flow from the north interceptorand minimizing the cost for the NorthBank Interceptor project. The team concludedthat a new gravity interceptor composedof approximately 40,000 LF of 54-inch,60-inch and 72-inch diameter sewer, whichwas an upgrade to the existing Crabtree LS,and 14,600 LF of 42-inch force main fromthe Crabtree LS to the downstream 66-inchgravity interceptors, could be constructedat a cost nearly equal to or less than the originallyproposed pump station, equalizationbasin and force main in the City’s CIP.The City selected the gravity interceptoralternative, now known as the Crabtree BasinWastewater System Conveyance Improvements(CBWWSCI). The project will bedesigned and constructed in phases.Locating Above-Ground Featuresand Underground UtilitiesThe City and the design team knew thatrouting a large-diameter gravity interceptorthrough a congested urban area, suchas exists along the Crabtree Creek existingsewer corridor, presented many design andconstruction challenges, including;• routing through existing greenway trailarea adjacent to residential, commercial,Tunneling will be required to install the gravity sewer under some of the roadway bridges along the alignment.Click Hereto return to Table of Contentswww.ncsafewater.org 71

Special Section: Buried Assetsand industrial properties;• nine crossings of Crabtree Creek ormajor tributaries;• railway crossings and major roadwaycrossings, including I-440;• installation under roadway and railwaybridges and a highway interchangeramp;• installation of 3,100 LF of sewer withinCity streets;• location very close to existing parallelgravity interceptors and otherunderground utilities;• crossing major utility lines, includingexisting large-diameter gravity sewers,water mains, storm sewer and fiberoptic lines;• deep installations within combinations ofrock and wet or saturated soils; and• installation across industrial andcommercial property with potential soiland groundwater contamination.The CBWWSCI included nearly everydesign obstacle one could expect in anurbanized area. Although preferred, thegravity sewer alternative limited the flexibilityof horizontal and vertical location. Therefore,the proposed route had to be fully evaluatedby the design team to accurately determinethe existing conditions and select an alignmentthat provided the most viable sewerplacement for constructability, serviceabilityand future maintenance. Subsurface UtilityEngineering (SUE) was the tool to accomplishthat task.SUE is an engineering practice that usesnon-destructive geophysical investigatingtechniques to verify the existence, conditionand exact location of underground utilities.SUE is available in four different qualitylevels:• Quality Level D: Information gatheredsolely from existing utility records.• Quality Level C: Involves surveyingvisible, above-ground utility facilities andcorrelating this information with existingutility records.• Quality Level B: Uses surfaceTest hole excavations enabled the team to verify horizontal designations, depth, material and sizeof the underground utilities along the proposed interceptor alignment.geophysical techniques to determinethe existence and horizontal position ofunderground utilities.• Quality Level A: Employs nondestructivedigging equipment (vacuum excavationvehicles) at critical points to determine theprecise horizontal and vertical position,as well as size and type, of undergroundutilities.Survey crews located and mapped abovegroundfeatures, and SUE specialists usedQuality Level B and Quality Level A servicesto designate and locate below-ground conditionsalong the proposed route. The SUEhorizontal designation included more than44,000 LF of underground utilities, includingelectrical power, natural gas, fiber optic, cabletelevision and telephone duct, potable waterlines, sewer force main, water and sewerservices, and some gravity sewer. All locatedfeatures were mapped to the horizontal NCstate plane coordinate system and the NorthAmerican Vertical Datum (NAVD) 88. Thecurrent FEMA floodplain mapping for WakeCounty is also on NAVD 88, making theproject design elevations relative.In one particular location along the proposedsewer alignment, the existing gravityinterceptor was anticipated to turn with aburied bend in the line (as opposed to amanhole). The SUE team located the bendutilizing electromagnetic (EM) technologyto designate the path of the existing gravitysewer. The team used the same technologyto obtain the vertical depth of the bend,allowing the design team to determine theappropriate new gravity sewer alignment.Following Level B designation, the SUEteam performed Quality Level A location atcritical points along the alignment. They usedtwo vacuum excavation trucks to excavatetest holes, enabling the team to verify horizontaldesignations and, more importantly,verify the actual depth, material and size ofthe underground utilities. Approximately 110test holes, ranging from 1 foot to 12 feet indepth, were performed along the 40,000 LFof alignment. Some of the more critical LevelA locations included the major 48-inch transmissionwater main, the Qwest fiber optic linewithin a Norfolk Southern railroad right-ofway,and gas mains along a congested citystreet where the sewer interceptor will beinstalled within the pavement.Where existing utility lines could not beaccessed by a vacuum truck, the SUE team72 NC Currents Summer 2011Click Hereto return to Table of Contents

used Ground Penetrating Radar (GPR) andEM technology to obtain reliable verticaldepth measures so the design team couldassess potential vertical conflicts with thegravity interceptor. Many of the utilities thatneeded to be located and verified with testholes were under pavement, requiring theSUE team to work closely with NCDOTand the City of Raleigh DOT to coordinatetraffic control and backfill of the test holelocations.All test hole data was recorded on astandardized test hole form with the testhole number, coordinates on NAD 83, depthbelow ground with top of pipe elevation onNAVD 88, material type, outside diameter,nominal diameter, asphalt depth, and utilitycondition. This information was enteredinto AutoCAD and provided to the designteam for entry into the plan and pipe profilesheets.In many locations, the proposed gravity interceptor will have to be routed between the existing gravityinterceptor and residential lots within the greenway area.Designing Aroundthe Underground UtilitiesWith the accurate survey and undergroundutility location work in place, the designteam proceeded with the final alignmentselection. The first critical alignment selectioninvolved location of the proposed72-inch gravity interceptor at the low endwhere the line will connect to the existingCrabtree LS. The interceptor had to berouted under two existing 60-inch gravityinterceptors and between concrete pillarsthat support the overhead interchangeramp. The route terminates at the pumpstation site, with connection to the existingpump station containing five 20 MGDscrew pumps.Other critical alignment selectionsincluded location of the interceptor proximateto the existing sewer interceptor andadjacent to residential lots or steep ridgeswhere there was very limited area. In severalof these locations, the engineers designedfor relocation of the existing (shallower)interceptor in a common trench with thenew interceptor so that both lines can bemaintained between Crabtree Creek andthe existing uphill obstructions.When completed, the new interceptorwill be 10 to 35 feet deep. The CORPUDstaff, with input from the design team,decided to design the proposed gravityinterceptor at elevations deep enough forthe pipe to maintain cover under all creeksAbove-ground electric transmission lines and buried large-diameter water and sewer mains makeaccurate above- and below-ground location essential.along the alignment. This design eliminatesa minimum of nine inverted siphons on thenew interceptor, reducing the need for theextensive maintenance that is inherent tosiphons and minimizing the potential forsewer failures and/or overflows and odorproblems.Most of the roadway crossings andthe railway right-of-way crossings will beaccomplished by conventional tunnelingusing steel plate liners or micro tunnelingwith pipe jacking. The design team willanalyze subsurface geotechnical informationcollected by soil borings along the alignmentto determine the preferred trenchlessinstallation method. Micro tunneling maybe considered where groundwater will beencountered and subsurface material isestimated to be fairly consistent.Researching Other Potential HazardsIn addition to evaluating the existingabove-ground and below-ground physicalinfrastructure, the team must alsoconsider potential hazardous subsurfacematerials, such as volatile and semivolatileorganic compounds (VOCs andSVOCs), and petroleum hydrocarbons.These materials may cause risk to workersduring construction, as well as adverselyimpacting the integrity of the gravityinterceptor over time.The engineering team is working withspecialized environmental subconsultants toperform environmental investigations in twophases. The first phase includes researchof environmental records with federal,state and local agencies, site assessmentsand interviews with property owners.

Special Section: Buried AssetsThere were a wide variety of environments SUE crews were exposed toduring the SUE phases of this project. A great deal of work took placeon city and state maintained roads and road shoulders. In addition, therewere two railroad right-of-ways to consider, multiple creek crossings,several aerial high-powered transmission electrical right-of-ways, greenwayareas congested with walkers and cyclists, and COR existing sewereasements.SUE professionals followed safety regulations at all times.Safety vests were worn constantly, traffic signs were set upon all roads, personal protective equipment (PPE) was usedduring the vacuum excavation activities (safety glasses, faceshield, steel toe boots, hard hats, long pants, hearing protection,gloves, back brace, whip checks on the air hose, etc.)There were no recordable incidences during this project.second phase includes soil sampling andtemporary groundwater monitoring wells.The soil and groundwater sampling willbe conducted at critical locations alongthe alignment where there is potential forcontamination based on the research,site assessments and interviews. Thereare known occurrences of past soiland water contamination in some ofthe industrial and commercially zonedregions along the alignment. The resultsof the environmental investigations will beessential in selecting the final alignment inthese areas.Where We Are NowCORPUD plans to complete the designand permitting of the CBWWSCI gravityinterceptor in the fall of 2011. Phase Iconstruction, which includes the first half ofthe gravity interceptor, is slated to begin in2012. The second half (Phase II) will beginbetween 2013 and 2014. The overall projectwill include a third phase with the upgradeof the existing Crabtree LS and installationof 14,600 LF of a 42-inch force main fromthe Crabtree LS to the existing downstreamdual 66-inch interceptors along the westside of the Neuse River.In SummaryThe City’s strong desire to find the most effective,reliable and economical solution toSSOs and I&Is led CORPUD away from theconstruction of a pump station and equalizationbasin with a very long force main.Officials recognized that this scenario, slatedfor a highly developed area, could become apublic nuisance and may not be as effective inreducing the risk of an SSO as a gravity seweralternative.Further study resulted in the selection ofthe gravity sewer alternative, which provedto be economically viable. The gravity sewersolution brought with it a new set of engineeringchallenges, requiring a high level of aboveandbelow-ground survey and SUE, furthersupported by environmental investigations.A successfully engineered gravity sewer projectwill minimize SSOs, use resources wisely,protect public and private property, improvecustomer service, protect surface water, andinstitute a long-term, sustainable solution toI&I and SSO challenges.About the Authors:Chris Windley, PE, is a Water Resources Engineeringproject manager with McKim & Creedand an engineer of the gravity sewer design forthe CBWWSCI project.

Special Section: Buried AssetsEngineering Technologies for Pipeline Asset ManagementBy Bryon L. Livingston, Ahmad Habibian, and Kent Lackey - Black & VeatchThere are many technologies availablefor managing the condition ofunderground infrastructure, or buriedpipe. In this article, we will focus on afew of the non-destructive technologiescommonly used in conducting conditionassessments in water systems. Thecondition assessment step is a keycomponent of the asset managementprocess, and knowing what technologyto use is important. Asset managementprinciples are not a new concept formost utilities, except that using aformalized approach provides a moreefficient use of the data collected.The formalized process providesfor converting data from conditionassessment to implementation ofprojects based on priorities.This article will identify why utilitiesshould be proactive in determining thecondition of the pipe in their system– especially those located in criticalareas. The condition-based assessmentwill show why it is beneficial to haveinformation on the actual condition ofthe pipe based on field evaluations,versus information based on statisticalmethods.Managing buried infrastructurerequires balancing the performance ofthe system; the associated risks; andcosts required with operational efficiency,planning requirements, affordable ratestructures, security, and regulatoryrequirements. The decisions made toreplace or repair/rehabilitate pipe shouldbe made based on the actual condition ofthe pipe in the system. The service life ofpipe is variable and is affected by manyfactors. The ‘wave’ of reinvestment is justbeginning, and utilities that take stepsnow to prepare for reinvestment needs willreap the benefits of early planning.News reports are full of many incidentsdescribing catastrophic events anddisruption to traffic and lifestyle resultingfrom breaks in water lines. It is impossibleand impractical to try to prevent all the linebreaks, but it is practical and also soundmanagement to prevent failures on criticalpipelines that can result in catastrophicevents. Effective planning and conditionbasedassessment are required to minimizethe number of such events. With aginginfrastructure, they are becoming morecommon. Now is the time to take action.Developing an inventory of the type(s) ofpipe in a system and the year(s) the pipewas installed will help determine the futureinvestment needs. However, not all pipesinstalled in the same year will fail during thesame year in the future. Evaluating thesefactors will provide data that is useful in thecondition assessment. There are severalfactors that impact the length of the servicelife of pipe, including:• third-party damage;• temperature, which createscontraction loads;• external loads from overburden andtraffic;• external corrosion from oilcharacteristics;• internal corrosion from water qualitycharacteristics;• transient pressures that affect thestructural integrity of the pipe;• design and construction practices;• bedding condition and material;• ground movement; and• groundwater and leakage.Understanding that these factors existand knowing how they affect the servicelife of pipe is important to manage therisk associated with buried infrastructure.Such factors cannot be eliminated, butthey can be managed. Several modelshave been used in the past to predict thecondition of pipe, including:• Prioritization Model,• KANEW Model,• Economic Analysis, and• Risk-Based Model (Monte CarloSimulation).These models are useful in developinga plan to identify areas to focus repairsin a replacement program. These toolswill not be discussed here, but arepresented for information. Rather, theengineering technologies listed below willbe discussed:• Visual Inspection and ClosedCircuit TV;• Electromagnetic (Remote Field EddyCurrent and Broad Band);• Ultrasonic, including G-Wave;• Remote Field Eddy Current/Transformer Coupling;• Acoustic Monitoring;• Leak Detection; and• Magnetic Flux Leakage(Currently used in oil and gas).76 NC Currents Summer 2011Click Hereto return to Table of Contents

This is only a partial list and there area number of technologies or variationsof these that are available. Thefollowing sections are summaries of thetechnologies listed.Visual and Closed-Circuit TV (CCTV)Visual inspection by entry into pipehas been used in the past as astandard method to inspect pipeinterior. This method is not as costeffectiveas in the past because ofOSHA requirements. Additionally,increased awareness of safety relatedissues associated with mannedconfined space entry make this optionless desirable and in some casesunacceptable.The technology for CCTV is makingdramatic improvements. It has beenused primarily in the gravity sewerlines, but improvements are making itapplicable for water lines. Unless thesystem’s pipes are full of tuberculation,there are some potential benefits fromusing CCTV inside a water line. Thepipe can be cleaned and CCTV wouldbe a valuable tool to identify internalcorrosion. The CCTV technology issimilar to that used in sewer lines; thecamera can pan and tilt to identifylost valves, build-up in the pipe, zebramussel, and various repair needs.The value of this technology couldbe used to enhance a repair programto investigate the condition of a pipefollowing a line cleaning.Broadband (BEM)Electromagnetic TechnologyThis technology is used for inspectingmetallic pipe; it measures wallthickness and pits using near-fieldelectromagnetic. The inspection iscompleted using an internal survey bydroid and an external scan by ‘blanket.’The pipe must be exposed and out ofservice in order for the inspection tobe conducted. Also for this inspection,the pipe must be very close to roundand the survey must be performed ina straight line. The inspection providesthe average thickness based on spotmeasurements at nodes. Based on theresults, an ultrasonic inspection can beused to confirm findings.Remote Field Eddy CurrentThis technology inspects the pipe wallfrom the interior of the pipe and is usedto assess the wall thickness of metallicpipe. This pipe includes:• ductile iron,• cast iron, and• steel.The inspection process detects internaland external defects equally well andcan identify pits (20mm) with metalloss or cracks. The application of thistechnology is limited because of theuse of linings in water piping systems.This technique is used in conjunctionwith ultrasonic inspection to confirmfindings. It was developed for oiland gas pipelines and has limitedapplications in the water industry. Asthe need for assessing metallic waterpipe increases, this technology hasthe potential to provide the informationrequired.Ultrasonic Inspection TechnologyThis technology is used for metallicpipes and requires an externalinspection to determine wall thicknessby measuring the transit time ofsound waves through pipe wall. Oneof the limitations of the technologyis that it can be used only for spotmeasurements. This requires a detailedevaluation of the pipeline to determinethe area most likely to contain wallloss or pitting. The pipe wall must bevery clean to provide a good contactbetween the sensor and the pipe wall.A couplant, an inexpensive handheldinstrument, is normally used to improvecontact. Some cities have purchasedthis equipment and conduct tests,known as B-scans, whenever there is aleak or access to the pipe. Advantagesof the B-scan are that:• it is accurate to three thousandths ofan inch,• it uses water as a couplant,• it displays the cross-sectionalthickness of the material,• it is very portable, and• it is five to 10 times faster thana conventional point-to-pointultrasonic.The limitations of the B-scan techniqueare that:• it can scan only surfaces that can bereached by the technician, and• it cannot scan pipes with heavilycorroded exterior surfaces.Impact EchoImpact echo is a simple test that is usedon concrete. The test measures thesound waves that result from striking theconcrete with a measured force. Thisprinciple is the same as using a hammerto strike the concrete and listening tothe sound. A hollow sound indicates thepossibility of separation in the concrete.Remote Field EddyCurrent/Transformer CouplingThis technology was developed to identifybroken wires in prestressed concretecylinder or non-cylinder pipe (AWWAC-301 and C-303). The electromagneticwaves are used to evaluate the conditionof the pre-stressing wires. The tool usesthe pre-stressing wires as an antenna,and the exciter in the tool transmits asignal that is recovered by the receiver.The technology measures the signal toidentify wire breaks. Normally, this processis used prior to acoustic monitoring toestablish a baseline, but it can be usedfollowing acoustic monitoring, if thesituation requires it. There are severalfactors that affect the electromagneticsignal, including:• wire anchoring methods,• variation in wire spacing,• variation in wire diameter,• variation in cylinder thickness,• wire splices,• shorting straps,• joint configuration, and• insulation in joints.Knowledge of the pipe is required toimprove the accuracy of the evaluation.Calibration of the pipe prior to theinvestigation greatly improves the results.Evaluation of the signal is an art as well asa science, and interpretation of the datarequires experience.Acoustic Emission Technology (AET)AET detects areas of active deteriorationby measuring the frequency and numberof distress-related acoustic events thatoccur along the monitored PCCP pipesection over a defined period of time.

Sahara ® Leak Detection TechnologyThis technology uses an acousticmonitor. It was developed in theUnited Kingdom and compliments theother technologies: Noise Correlation,Acoustic Leak Detection, and Metering.Sahara ® Leak Detection Technologycan be used on any pipe of any material;the data results are identified in realtime. The significant difference in thistechnology is that it can detect andprecisely locate leaks as small as 0.5gallons per hour. The inspection islimited to 5,000 feet and 12-inch orlarger pipe.A recent project found a mediumleak that, when excavated, revealed thata large area had been washed away.Finding the leak prevented a potentialcatastrophic incident and alloweda scheduled repair rather than anemergency repair.Complete the Condition AssessmentWith the data from a conditionassessment, it is possible to identify theright pipe to be replaced or repaired.The use of a risk analysis will determinethe right time required and engineeringprinciples will determine the rightmaterial. Using asset managementprinciples, it is possible to incorporateknowledge of pipe condition into aprogram for managing pipeline assets.With knowledge from thetechnologies to properly manageinfrastructure, a process must bedeveloped. The condition assessment isthe first step and results in documentedresults that are used to identify projectswhose cost can be estimated forincorporation into a capital improvement.The projects are then prioritized basedon the risk evaluation and are rankedusing risk criteria.The amount invested in pipelineinfrastructure constitutes a large portionof a utility’s assets and can be the majordriver for altering investment needs.In contrast to treatment works, pipereplacement and rehabilitation requirea sustained flow of expenditures, nota periodic capital expense followed byyears of service. As stated previously, allpipes ‘born’ in a given year will not ‘die’during the same future year.The focus on buried infrastructure isbalancing performance, risk, and cost.The basic steps to managing pipelineinfrastructure are:• conducting a condition assessment,• developing a program,• prioritizing based on risk analysis, and• implementing the plan.The approach is summarized by thefollowing equation:R3 = Replace the Right Pipeat the Right Timewith the Right Material.About the authorsBryon L.

Special Section: Buried AssetsCity of Concord, North Carolina Sewer EasementLocation, Notification and Education ProgramBy Gary Fritz, City of ConcordOne aspect of managing a wastewater collection system’sassets is verifying or securing easement rights, while maintainingthe accessibility of the easements. The City of Concord staffmaintains approximately 534 miles of gravity sewer lines. Ifthese lines were placed end to end, they would extend from theCabarrus County Courthouse to the gates of Disney World. Themajority of the sewer lines are located within the street rightof-ways.However, there are occasions where it is necessary toplace the sewer line in an easement on private property in orderto maintain the slope required for gravity flow. Some propertyowners are unaware that these lines or easements are on theirproperty. As a result, many sewer easements are built upon,landscaped over or fenced in, which inhibits the City’s ability toproperly access these sewer lines for necessary maintenance.Rapid development, coupled with smaller parcel sizes,has created an accessibility problem for the City of ConcordWastewater Resources Department crews. Understanding theissue confronting them and preferring to be pro-active rather thanreactive, Concord staff developed a program in 2006 to reducethis potential problem.The City of Concord’s program systematically locates sewerlines and easement documents in three parts. Once the sewerlines and documents are located, property owners are notified oftheir existence and the easements are flagged in the City’s utilitybilling system and GIS. If the flagged parcel changes ownership,a notification in the billing system alerts the City’s WastewaterSystem Compliance Officer and a notification letter is sent to thenew property owner. The notification letter includes informationabout the City’s property rights along with the correspondingdeed book and map book reference.The program’s three phases are:Phase I – Location of the easement, along with notifying andeducating the property owner as to what they can and cannotdo within an easement.Phase II – Identify any easement encroachment and notify theproperty owner in writing of the finding.Phase III – Correction of the encroachment issue.Properties in Cabarrus County within and outside of the City ofConcord are identified in two ways, either with the parcels addresspoint or the use of the PIN (parcel identification number). There are34,574 PIN numbers currently within the area covered by the City’swastewater system. Of this amount, 3,653 parcels have a sanitarysewer line on some portion of the property.Initially, the questions were how to implement the program andwhere to start? The outer rim of the City of Concord was wheremost of the development was occurring, while the center City wasolder, more developed, and had less accessible easement documentation;thus, may be more time consuming to locate the existingeasement. It was decided that starting on the outer boundaries ofthe City limits would provide the most benefit for the utility crews.In these areas, the typical lot sizes were small (.14 - .18 acres) andsewer line locations ran through many back and side yards insteadof within the street right-of-ways. This particular area was where thegreatest construction was occurring. In addition, information regardingeasements needed to be provided to the residents before theirhome improvement projects created accessibility situations.The next question was how should City staff divide the collectionsystem for parcel research? Using the City’s current GIS database,the service area was already divided into 459 sewer basins, with theCity’s sewer lines located and plotted. Of these basins, 126 did not30 foot easement. 2 sheds, fence, home addition constructed onthe easement.Storage facility built on top of sewer easement green line is sewer line.80 NC Currents Summer 2011Click Hereto return to Table of Contents

presently have sewer service. This left the City’s Wastewater ResourcesDepartment staff with 333 basins that had sewer mains.Next, the sewer line locations were checked in relation to the streetright-of-way layer to find occurrences where the sewer line wasinstalled outside the road right-of-ways.Finally, since the information would need to be easily accessibleto multiple Concord departments, City staff considered wherethe information should be archived. With the exception of a smallnumber of residents on a private well, the City is the major supplierof drinking water. Therefore, this made the water utility account inthe utility billing system the ideal location to store easement data.By attaching the easement location information to the water utilityaccount, the information was readily available to all Concord departmentsand allowed for ease in tracking change of residency orparcel ownership. Once a particular parcel was identified as havinga sewer line crossing it, further research was needed to ensurean easement exists. Using plat information and deeds, the searchgoes through the Cabarrus County Register of Deeds office. Propertyowners are then determined and subsequently notified of thedocumentation.The notification sent to the property owner is just for theirinformation. Should the parcel already contain an easementencroachment, the encroachment will be located in Phase II andaddressed in Phase III. If the property owner desires to have thesewer line, manhole or easement located, the City’s WastewaterResources Department staff is available for assistance. The owneris encouraged to call for assistance when considering constructingfences, gates, sheds, swimming pools, swing sets, irrigationwells, detached garages, planting trees and landscape plantings.All these potential lot improvements, coupled with a sewer line, area recipe for future problems. Doing nothing and ignoring the sewerline is NOT the answer.One problem the City staff encountered along the way involvedparcels that did not have an address point. These parcels have notbeen developed and had no link to a water utility account, so staffcould not attach easement information as with the other parcels.Similarly, parcels with an address point, but on a well and septicsystem, were also void of a water utility account.Development of a dummy water utility account was the cure toboth situations. By implementing a ‘No Water Service /Has RightOf Way Account’ in the utility billing system, City staff could attachthe easement information to the parcel with an address point.The parcels that did not have an address point were assigned autility account using the owner’s address, along with the parcelidentification number of the parcel with the sewer line. This dummySewer line (green line) with a swimming pool constructed on top.account also allowed for tracking of the parcel during change ofownership or parcel development.The entire easement program focused on the basins containingrapid development first. Within these basins, easements wereeasy to locate and the time spent doing research was minimal.The program then refocused on older sections of Concord, whichtypically consisted of older lines and areas with either hard-to-findor non-existent easements.Upon reaching the older section of the City, there was a needto accelerate the program by sub-dividing Phase I into Phase IAand IB. Phase IA consisted of parcels with identified easementsand Phase IB included parcels where no recorded easementswere located for the sewer line. At this point, City staff developeda different letter that informed the parcel owners in Phase IB thatthere was a sewer line crossing their property. The absence ofeasement information was not addressed at this time. This divisionallowed for an accelerated completion of the initial goal of sewerline location and resident notification. At a later date, documentresearch will be conducted by City staff in an effort to locate easementinformation that is missing in Phase IB.Upon completion of the final basin review, a new color-codedGIS layer was developed for easy identification of the following: 1)parcels with easements, 2) parcels with sewer lines, but no easementsof record, and 3) City owned property. Completion of thislayer allowed City staff to evaluate the program and locate parcelsthat may have been initially overlooked or developed after thebasin received its initial review.Click Hereto return to Table of Contentswww.ncsafewater.org 81

Special Section: Buried AssetsAs Phase I drew to a close, 3,653 parcels were identified asparcels that contained a sewer line. Of these, 3,096 were found tocontain an easement and 557 were placed in Phase IB for furtherdocument research. Of the 557 parcels in Phase IB, 22 were foundto be City owned properties.Through the easement program, City staff discovered that alarge number of parcels changed hands annually. In addition, Citystaff needed a way to remain current on ownership changes, especiallyfor properties with sewer lines crossing them. To address this,the entire list of address points that have sewer lines crossing theproperty is re-visited every three months, using a computer searchprocedure. Any change in residency is noted and the new residentis sent a movement letter containing the easement information. Todate, 1,320 movement letters have been generated.Once all the basins with sewer lines had been reviewed, andCity staff were certain that all affected parcels were identified, theprogram shifted into Phase II. Phase II featured a physical inspectionof each identified parcel for any easement encroachment. Thisinspection either labeled the parcel as free of encroachments orone that will need to be addressed in Phase III. Once the encroachmentsare identified, they are photographed and transferred to anelectronic file. This file is a separate filing system and is not to beconfused with the archiving of easement information on the utilitybilling system. In addition, this file, organized by address point andPIN numbers, contains all information and correspondence relatingto the easement and the encroachment. Each of the 3,653 parcelswill be visually inspected every year to check for any building activity.Once identified in Phase II as having an easement encroachment,the parcel enters Phase III, where the resident receives a letter fromthe City’s Wastewater Resources Department, a copy of the easementdocument, and a photo of the encroachment. City staff then asks theresident to contact the department upon receipt of this information.Working with the resident, the City’s staff attempts to arrive at a solutionto the accessibility problem that is in the best interest of both theCity and the resident. The goal is to correct existing encroachmentsand prevent future encroachments through dialogue.Most encroachments can be corrected very easily. Fences requirea gate, sheds need to be on skids and relocated, and landscape plantingscan be adjusted to incorporate the easement. Swimming pools,trees and detached buildings create a bigger challenge and requiremore thought and resident cooperation to arrive at a solution.Finally, the overall goal of Concord’s program is easement identification,resident notification and homeowner education. By workingwith the City’s residents, providing accessibility for City’s crews willcome through communication and cooperation.About the authorGary Fritz is a graduate of the University of Wisconsin & Universityof Wisconsin-Milwaukee.

Special Section: Buried AssetsEffective Use of Infrastructure Funds:Prioritizing Pipe Rehabilitation ProjectsBy Meg Roberts, P.E. Senior Principal Engineer, Hazen and Sawyer, P.C.Crystal Broadbent, P.E. Senior Principal Engineer, Hazen and Sawyer, P.C.As water distribution systems age, utilities are faced with theneed to rehabilitate water mains to minimize leaks and restorecapacity lost from tuberculation. Due to high costs and limitedfunds, utilities must prioritize rehabilitation projects to provide thebest return on investment. Prioritizing pipe improvements canbe done by conducting desktop evaluations or using specializedsoftware packages. The end result is a scoring system that allowsthe utility to address the most critical needs first.Several criteria should be considered to prioritize pipes forrehabilitation. The importance of each factor varies among utilities.Input to the analysis may include: main break history, pipeage, pipe material, valve status, soil pH, pressure, flow velocity,and proximity to critical facilities, such as hospitals. A scoringand weighing system is assigned for each input, and each pipeis then assigned a weighted sum. The higher the score, themore critical the pipe is to the system and the higher the priorityfor rehabilitation.For example, pipe material can have an impact on water quality.Unlined cast-iron pipes are known to become tuberculatedand harbor biofilms that decrease disinfectant concentrations.Water quality is a high priority for all utilities, and, thus, pipe materialmay be weighted more heavily than another factor.After prioritizing, the pipes can be tabulated and mapped,with rehabilitation costs estimated for each. Pipes can begrouped into annual projects that conform to budget constraints.The best methods of rehabilitation for each pipe (e.g., pipereplacement vs. pipe lining) can then be evaluated based on factorssuch as constructability and site conditions.This article will describe a case study in Roanoke Rapids,NC. Methods of prioritizing pipes, assigning scoring values,making repair or replacement decisions, and estimating costswill be discussed.Case Study:Roanoke Rapids Sanitary District (RRSD or the District) is locatedalong Interstate 95 in eastern North Carolina, about five milessouth of the Virginia border. The District comprises an area ofapproximately 15.6 square miles. The District’s water distributionsystem includes roughly 120 miles of pipe (6-inch diameter andlarger) that supply more than 9,000 water customers. It includesparts of both Halifax County and Northampton County, all of theCity of Roanoke Rapids and Town of Gaston, and parts of theTown of Weldon.Raw water is taken from Roanoke Rapids Lake which is animpoundment on the Roanoke River. The water distribution systemwas originally built by a manufacturing company to supplythe needs of its cloth and paper mills. RRSD was formed in 1931and, in 1933, took over part of the water distribution system andexpanded it. This included the construction of an elevated tank.A second elevated tank was built on in 1951 and the distributionsystem was greatly expanded to the east, south, and west in1957. The District expanded to the north in 1977, when a 12-inchtransmission main was installed to supply the Town of Gaston.Further growth in the 1970s and 1980s included construction ofa third elevated storage tank in 1987.Pipe Condition: Approximately half of the water mainsin the Roanoke Rapids Sanitary District (RRSD) distributionsystem are older than 1950. In North Carolina, pipes installedbefore this time were predominately unlined cast-iron, whichis prone to tuberculation and also leaky (lead or leadite) joints.Many distribution systems have pipe roughness that is mainlydependent upon pipe material and lining. An example of sucha utility is shown in Figure 1. C-factor tests were conductedand results plotted against pipe installation dates. Pipe installedbetween 1900 and 1950 was unlined and, on average, had a84 NC Currents Summer 2011Click Hereto return to Table of Contents

Hazen-Williams C factor of 34. Lined pipe installed in the 1950sthrough 1990s had an average C factor of 120.Aging infrastructure has caused a variety of problems in theRRSD distribution system. Leaks have become more numerousover time as pipes deteriorate. A water audit determined thatleaks accounted for a significant portion of non-metered andunbillable water, making water losses a financial problem. Breaksnot only result in water loss, but cause interruption of service andpublic safety concerns. Older pipes are tuberculated, causingmore head loss and reduced fire flows.Prioritization Method: Because such a large portion of thedistribution system is unlined cast iron, RRSD needed a methodto prioritize renewal efforts. Prioritizing was a challenging taskbecause it involved making many decisions about which pipesto renew and when. This process required integrating all relevantavailable information about each pipe.A scoring system was established using InfoWater CapPlansoftware (MWH Soft, Version 2.0). Creating a pipe renewal planwith this software involved four general steps:1. Estimate Likelihood of Failure of each pipe (LOF).2. Estimate Consequence of Failure of each pipe (COF).3. Estimate Risk: Use consequence and likelihood of failure toestimate the overall level of risk for each pipe.4. Produce Pipe Rehabilitation Plan: Prioritize based on risk anduse unit cost data and budget information to create a piperehabilitation plan.We estimated the likelihood of failure for each pipe by considering:• Failure History Data: Two sets of data were used to indicate thefailure history of each pipe. One was the number of repairs foreach pipe, and the other was the status of valves on each pipe.Pipes with a larger number of repairs and more valves in poorcondition were considered higher risks.• Pipe Attributes: The two pipe attributes used to indicate riskwere pipe material and type of joints. The pipe age was used toestimate the pipe material and the type of joints.• Hydraulics: The hydraulic model was used to predictpressures. Higher pressures increase the relative likelihood offailure.A score from 0 to 20 was given to each pipe based on thoseFigure 1: Example of Field-Tested C Factors versus Year Installeddefinitions. Unlined cast iron pipe, for example, was given thehighest score of 20 for pipe material, whereas ductile iron wasgiven a score of zero. Each parameter was then weighted on ascale of 1 to 10. An adjusted score was then calculated for eachpipe using the following equation:Adjusted Score = Weight * (Parameter Score) ^ Exponent (Equation 1)Pipe material was given an exponent of 2 to ensure that unlinedcast-iron pipes would be the highest priority for rehabilitation. Allother parameters were given exponents of 1.We analyzed the consequence of failure for each pipe byconsidering:• Critical Facilities: Critical facilities identified in RRSD wereschools, hospitals, natural gas and power facilities, state-ownedfacilities, and critical manufacturing customers. Pipe failuresnear such facilities have higher consequences.• Isolation: Isolation analysis determined how much of thenetwork would be out of water if a pipe was shut off for repair.This was done by tracing the network in all directions untilvalves were identified that would isolate the subject pipe.

Using flow instead ofvelocity helped reduce the risk of over-weighting smaller pipesthat may be overloaded but do not transport much water.• Fire Flow Improvements: Another important consideration for thisinfrastructure renewal plan was to improve fire flows. Pipes thatwould eliminate an existing fire flow deficiency if the C factor isrestored were assigned a top priority for rehabilitation. Pipes inareas where fire flows would be deficient even after cleaning andlining were candidates for replacement with larger pipes.A score from 0 to 20 was given to each consequence definition.Pipes associated with a high flow, for example, were given the highestscore of 20, whereas low flow pipes were given a score of 1.Each parameter was then weighted on a scale of 1 to 10 with oneexception. A weight of 20 was given to each pipe with deficient fireflows in order to assign highest priority for those pipes. An adjustedscore was calculated for each pipe by adding all the individualparameter scores according to Equation 1. All consequence scoreswere given exponents of 1.The CapPlan software estimated the overall risk level of eachpipe using the consequence and likelihood scores and applying abi-directional distribution risk assessment.The bi-direction distribution classified the range of scores intolow, medium, and high risk levels, for both consequence and likelihoodof failure. Scores in the lowest 10% of the score range wereclassified as ‘Low.’ Scores in the 10-60% range were classified as‘Medium,’ and scores in the top 40% of the range were classified as‘High.’ A matrix was defined for overall risk assessment as shown inTable 1.Results and Discussion: A color-coded map was generatedshowing the relative priority of all distribution system pipes (Figure 2).After prioritizing each pipe, we also addressed the followingquestions:1. How should each pipe be rehabilitated?2. What will be the annual cost of rehabilitation?How a pipe should be rehabilitated means deciding whether a pipeshould be cleaned and lined, replaced, or otherwise repaired. Thisdepends on several factors:• Joint type: Lead and leadite joints were commonly used in pipesinstalled before 1956. These types of joints sometimes causeleakage, even after a pipe has been cleaned and lined. However,there are relatively new lining materials and methods that offerstructural integrity at joints and may be cost effective (polyesterreinforced polyethylene pipe or Class III structural polyurea coating,for example).• Available Fire Flow: If a pipe with a low C-factor is located inan area with a deficient fire flow, two solutions are possible.The pipe could be rehabilitated (cleaned and lined or replacedwith a new pipe of the same diameter), which would decreasehead loss, thus improving the available fire flow. However, ifrehabilitation does not eliminate the fire flow deficiency, thepipe should be replaced with a larger diameter pipe. In RRSD,approximately half of all the deficient fire flow locations wouldbe improved by rehabilitation (assuming C factor of 120),and those that are not were addressed as part of a capitalimprovement plan.• Site Restrictions: Replacing pipes in most cases requiresdigging a trench and installing new laterals (or service linesfrom each residence). Logistically, with respect to construction,this can be difficult at some locations. Downtown areas withbusy streets, for example, are typically problematic due toother utilities, pedestrians and traffic. Cleaning and liningavoids many site constraints, as would pipe bursting andreplacement methods, however, temporary service to eachresidence must be installed above-ground while the pipes arecleaned and lined. Above-ground temporary connections maybe a problem at some locations. There are some technologiesthat limit service disruption to one day, eliminating the need fortemporary service.Table 1: Bi-Directional Distribution Matrix of Overall RiskScores Likelihood ofFailure –LowLikelihoodof Failure –MediumLikelihood ofFailure –HighConsequence Medium High Extreme– HighConsequence Low Medium High– MediumConsequence– LowNegligible Low Medium86 NC Currents Summer 2011Click Hereto return to Table of Contents

• Cost: The unit cost estimate for cleaning and lining for theRRSD project was about $6.50 per inch of diameter per linearfoot (inch-foot) of pipe. This was an average based on recentcleaning and epoxy lining projects in North Carolina and includeslabor and other relevant expenses. Average replacement costswere approximately $5.80 per inch-foot for PVC and $7.25 forductile iron. These costs also include labor and other relevantexpenses. According to RRSD staff, recent repairs, on average,cost approximately $600 per break or more depending on thelocal conditions. On a unit cost basis, there is little cost differencebetween replacing pipes or cleaning and lining. On an annualbasis, repairing pipes that leak or break may be less expensivein the short term. However, as pipes continue to age, more andmore repairs will be necessary and, therefore, consume more ofthe annual budget. Other costs that are difficult to quantify withrespect to pipe breaks include water loss (unbilled water), publicsafety, and staff exposure to hazardous conditions.Other factors to consider are water quality and public relations.Repairing breaks does not improve water quality, but cleaning andlining or replacing a tuberculated pipe greatly improves water quality.Making numerous repairs on a recently paved street is guaranteedto create a public relations problem.For RRSD, a detailed rehabilitation plan was outlined. The orderof rehabilitation was based on the pipe prioritization as describedabove. RRSD will consult with local contractors when starting therehabilitation plan. There could be cost savings based on specificsite conditions for rehabilitating certain pipes as part of one projectsensus_horiz_ad_001A_final:Layout 1 9/24/2010 4:09 PM Page 1in a localized area, even if those pipes are not high on the prioritylist. Because unit costs were very close for RRSD, estimates willbe obtained on a site by site basis to determine the cost differencebetween cleaning and lining or replacement.The annual budget required to rehabilitate all the unlined castiron pipes for RRSD within the next 20 years was estimated tobe approximately $375,000 (in 2010 dollars). RRSD used thisestimate for planning an adequate annual budget for infrastructurerenewal. The rehabilitation schedule can be adjusted depending onavailable funding.By using a systematic approach to prioritize pipes forrehabilitation, a utility can make efficient use of its funds.Planning for pipe rehabilitation or renewal is an important steptoward maintaining a safe and functional distribution system asinfrastructure ages.About the AuthorsMegan G.

Human andEducational ResourcesInnovative Solutions:Detlef KnappeConducts Research thatBenefits Drinking Water UtilitiesFor more than 20 years, Dr. DetlefKnappe has been involved in developingsolutions for the treatment ofdrinking water. His research has included awide range of projects, some quite fundamentalin nature, others more applied.“I still remember when I joined NorthCarolina State University’s (NCSU’s) CivilEngineering department and received fundingfor my first project,” recalls Knappe. Theresearch was focused on algae detection,control and removal strategies. Fundedby the American Water Works Association(AWWA) Research Foundation and theNorth Carolina Urban Water Consortium,the project looked at the optimization oftreatment to mitigate the impacts of algaeand algae control on finished water quality.“The results were directly implementable,”says Knappe. “A number ofrecommendations from that project havebeen adopted by utilities in North Carolinaand beyond in terms of selection of treatmentchemicals such as polymers thathelp with algae removal.” The research alsoassisted utilities in addressing questionsrelated to online monitoring and maintainingeffective coagulation conditions during algaeblooms, when raw water pH can fluctuatedramatically.This research project at NCSU reflectedone of Knappe’s many interests in waterquality and treatment, a passion born fromhis early interests in environmental protection.As a young student growing up inGermany’s Black Forest, he was especiallyconcerned about the adverse effects of acidrain on the health of trees. In the late 1980s,his curiosity about life in the United Statesled him to a community college in Illinoisand then on to the University of Illinois atUrbana, where he embarked on a degreein Civil Engineering with a concentration inEnvironmental Engineering.It was there that he met Dr. Vernon Snoeyink,the man he credits for his decisionto dedicate his career to studying drinkingwater treatment. “When I took his water andwastewater class, we connected very well,”recalls Knappe, adding that the two spentcountless hours talking outside of class.In fact, the young undergraduate wasamazed that such highly regarded NationalAcademy of Engineering Members as Snoeyinkand Dr. Dick Engelbrecht would takethe time to be so accessible to students.“They never gave the impression that theywere too busy to talk to an undergrad,” hesays. “I take that as my own motto when Ideal with students.”As a professor, Knappe emulates hismentors in many other ways. For instance,he encourages his students to engage inlaboratory research, right from the undergraduatelevel. “That’s something I put ahigh value on,” he confirms, adding that,at any given time, he is working with twoto four undergrads in the lab. “It exposesthem to research and it’s also a nice way tosee who is a good candidate for graduateschool.”Early exposure to the lab—at a timewhen undergraduate research was relativelyuncommon—was instrumental to Knappe’sown advancement. The opportunity allowedKnappe to become involved with theinvestigation of disinfection by-product (DBP)precursor removal in membrane treatmentprocesses, a leading-edge technology at thetime. In 1991, he continued on to a MastersDegree, with research focused on the regenerationof granular activated carbon.For his Ph.D., Knappe conductedresearch on a project funded by CompagnieGenerale des Eaux (now Veolia), investigatingthe removal of the herbicide atrazine by bothpowdered and granular activated carbon.During his visits at Anjou Recherche inFrance, he had the opportunity to visit someof the utilities that supply Paris with drinkingwater. Knappe remembers being impressedwith the speed with which leading-edgetechnologies such as nanofiltration were beingintegrated into the existing infrastructureof French utilities.Since joining North Carolina State University(NCSU), a big focus of his researchhas been on activated carbon and high-silicazeolite adsorption processes. “With zeolitemolecular sieves, we wanted to see whetherwe can selectively target the removal ofa contaminant from water while leavingother constituents in the water that wouldotherwise interfere with the effectiveness ofactivated carbon adsorption processes,”says Knappe. One project, funded by theAWWA Research Foundation, looked at thedevelopment of an effective and environmentallyfriendly adsorption/regeneration systemfor the removal of methyl tertiary-butyl ether(MTBE).MTBE is a common problem for groundwaterutilities where wells have been contaminatedby leaking underground gasoline88 NC Currents Summer 2011Click Hereto return to Table of Contents

Although zeolite molecularsieves are more expensive, they can processfour to five times as much water beforerequiring replacement or regeneration.“Molecular sieves may also be easier toregenerate onsite than activated carbon,”notes Knappe, adding that, up to this point,he is unaware of any full-scale installationsusing this technology. “It’s something we’rehoping to pilot in order to illustrate thepotential more clearly.”On the other hand, zeolites are ineffectivefor disinfection by-product (DPB) precursorremoval. Even powdered activatedcarbon, which is used by several utilities inNorth Carolina, can require relatively highdoses to reduce DPB formation to levelsthat meet regulatory requirements. Butsuperfine activated carbon can remove twoto six times the amount of DBP precursorsthan can be removed with traditionalpowdered activated carbons, says Knappe.“As a result, utilities may be able to meetDBP regulations with much lower carbondoses,” he adds. Having an effective toolfor DBP precursor removal may also giveutilities flexibility in choosing between freeand combined chlorine as the disinfectantfor the distribution system.An additional benefit, he points out, isthat superfine carbon is very effective forthe removal of taste and odor compoundsand emerging contaminants such aspharmaceuticals and endocrine disruptingchemicals. “More recently, we have startedto focus on a new class of emerging contaminants,the perfluorinated compounds(PFCs),” he notes. In a project funded bythe Water Research Foundation, Knappeis evaluating the effectiveness of superfineactivated carbon and magnetic anion exchangeprocesses for the removal of PFCsfrom drinking waters sources.What all of these research projects havein common is that they not only addressproblems of real and immediate concerns tomunicipalities, but also seek practical solutionsthat can realistically be implemented bythe utilities in the near future. Knappe alsoserves on the AWWA Standards Committeefor Activated Carbon. An important aspectof the work is to develop information thataids utilities in procuring activated carbonthat effectively meets their treatment needs.Utilities can choose from a large number ofdifferent activated carbons, but the cheapestcarbon on a per pound basis may notnecessarily be the carbon that meets thetreatment goal at the lowest cost. ExplainsKnappe: “That’s why a lot of our work hasfocused on developing a better understandingof activated carbon and craftingperformance-based selection criteria thatcan help utilities better choose a carbon thatgets the job done at the lowest cost.”Besides research, teaching is anotherimportant component of Knappe’s life.“Over the years, we have incorporatedmany concepts into our courses at NCState University that were not emphasizedmuch during my college years,” he says,adding that topics such as sustainability,life cycle analysis, the water-energy nexus,water reuse, and appropriate technologiesfor developing countries represent importantadditions to the university’s EnvironmentalEngineering curriculum. “One thing I try toinstil in my students is to not just acceptthe status quo but to think of new ways oftreating water. I also tell them ‘don’t just tryto meet regulations. When you are choosinga water treatment approach, questionwhether you are truly improving the quality ofthe water.”Another trend Knappe has observedover the years is that students have a muchgreater passion for service. “Many of ourstudents are keenly aware about the globalneeds to provide greater access to improvedwater and to sanitation,” he says, “and theyare very motivated to make a difference.” Asa technical advisor for the NCSU chapterof Engineers without Borders, Knappe isexcited to be mentoring students who areundertaking water and sanitation projects inBolivia and Sierra Leone.He also serves as the faculty advisor forthe student chapter of the NC AWWA-WEA.“I’m really happy to see how the YoungProfessionals in the state interact with ourstudent group,” says Knappe. From resumebuildingto connecting at state-level conferences,the relationship between student andpractitioner is always beneficial. Knappe alsoprovides students with opportunities to presentresearch at conferences as an incentiveto polish their oral and written communicationskills. Once or twice a year he takes asmany students as he can to national conferencesso they can present their work andinteract with water treatment professionals.“Having a bright student populationinterested in making a difference keepsme motivated,” says Knappe. “One of thethings that makes my day is a student whoasks a question I can’t answer.” After all, itwas these very types of questions that oncebrought a young German student across theAtlantic in pursuit of ways to make the worlda better place. It is a mission that, today, heis just as determined to pursue.Click Hereto return to Table of Contentswww.ncsafewater.org 89

News and NotesCapturing Association MemoriesRegular attendees at Association events,particularly the Annual Conference andCollection and Distribution Schools, aresure to have noticed Jane DuBois. Shecan be found floating from event to eventand close to the stage at every awardsceremony capturing the moment with hercamera. If you have not seen Jane herself,you are sure to have seen her work.Photos she takes at Association eventsappear on the web site, in this magazine,and in other Associationproductions,bringing events to lifefor those unable toattend and remindingthose that did of thegreat time they had.Jane’s interest inphotography started about seven yearsago when she was taking pictures of familyand realized that she really enjoyed it. Toher, photography is a form of communicationthat tells a story that will live on beyondher and the subject of the photo. Hergoal is to catch people being themselvesand show the emotion of a moment. Janesays, “When someone hears good news,or experiences sadness, pain, suffering,joy, silliness or tranquility, that is when Iwant to capture that moment, that is whatI want the photo to show – pure emotion.Then, it is real, honest and fresh.”Jane wants taking pictures to stay funand enjoys the rewards that volunteeringher talent brings, so she would neverconsider doing photography professionally.“To me it is a pleasure and an honor totake [Association] pictures. To me, it hasalways felt like taking pictures of my family.I get a lot of joy at how everyone likes mypictures, when they see themselves andthey like the way I captured them, thatmeans everything to me. I feel very specialwhen someone wants me to email themthe pictures I took of them – that feels reallygood to me.”When not taking pictures, Jane feelsvery fortunate at this time in her life thatshe can spend quality time with her family.From holidays to nature walks, Jane isalways planning activities for her family, especiallyher 5 1/2 year old twin grandsonsBryce and Britton. If you know her husbandTony DuBois, then you know therewill always be some kind of adventure.It is Jane’s love of taking pictures andgetting to know people that have made hersuch a valuable asset to NC AWWA-WEA.Without Jane, some Association memoriesmight go unnoticed or be lost from the officialrecord of our history.

To raise the fundingfor this equipment, Hach employeesdonated money and hosted a bake sale andraffle within the company; Hach Companydonated funds to match those donated/raised by the employees; and Hach customersdonated loyalty points towards $7,000 worth ofproducts.Initially, Hach sent representatives to Haitito assess what was most needed. Hach metwith the State University, which had suspendedlabs and was holding classes in the library; theUniversity of Quisqueya, a non-profit foundationto educate students in science programs, whichwas rebuilding its facility; and CAMEP (CentraleAutonome Metropolitaine D’eau Potable), thestate-owned company that manages waterresources and distribution for the capital cityof Port-au-Prince and its surrounding areas.Hach learned how monitoring water quality wasbecoming increasingly difficult due to the lackof portable field instruments, the challenges ofbringing samples into labs, and lab instrumentsthat were rendered inoperable due to the earthquake’sdestruction.As a result, Hach has helped restock theCAMEP lab with $77,000 worth of Hachproducts including DR2800 spectrophotometers,2100Q portable turbidity meters, DR980colorimeters, reagents, and much more. InOctober 2010, Hach representatives returnedto Haiti and CAMEP to ensure the donatedproducts were received and to train recipientson how to use the products. Responding to thecall from multiple non-profits seeking to providesafe water in Haiti, Hach has supplied an additional$47,000 worth of Hach products to WaterMissions International, Mercy Corps, InnovativeWater Technology, Oxfam, International Action,and Haiti Outreach.“Hach was founded on the principle of bringingclean water to the world. Our employeesare proud of this mission and they stepped upto raise the money to bring Hach water analysisproducts to Haiti,” Renee Garcia, chairperson ofHach’s Donations Committee explained. “Withover 3,000 deaths in Haiti from cholera in recentmonths, clean water still remains a highestpriority.

NC Currents Future ThemesNC Currents is the official publication of the NC AWWA-WEA. Members, individuals and committees are encouraged to submit contentfor the magazine. If you would like to submit an article to be considered for publication in NC Currents please complete the SubmissionForm & Publication Agreement (available at www.ncsafewater.org) and email both the completed form and your article to Nicole Banks atnbanks@ncsafewater.org. Articles must be received by 5:00 pm EST on the listed submission deadline.The editors of NC Currents welcome the submission of all articles related to the water and wastewater industry. Themes serve as generalguidance for each issue, but articles are not limited to an issue’s specific theme. Submission of an article does not guarantee publication.The Editorial Committee will review and select all articles and authors will be notified of the status of their submission.FALL 2011Educating Our Communities; Effective Public Education Efforts in North Carolina (Submission Deadline July 11, 2011)Effective public education is the cornerstone to our future in all aspects of life (career, personal life, social life, etc.). It helps providedirection and development of the younger generation in regards to choosing their career path and becoming actively involved with theircommunity either individually or through a society or professional association or even on the political front. Public education will alwaysbe the key that provides essential knowledge and a clear path an individual needs not only to improve our overall standard of livingbut also to reach pertinent personal and professional goals. The NC AWWA-WEA is proud of its ongoing support of public educationprograms and activities which will make our association even stronger in the years to come. How is this accomplished? By expandingour positive public image through outreach and public relations, attracting young professionals to our industry, and providing a catalystfor coordination and involvement with our communities and organizations across North Carolina. The NC AWWA-WEA CommunicationCommittee is soliciting articles that relate to the development, coordination, and implementation of public education programs andactivities in our local NC communities that advance the knowledge and awareness of our most precious natural resource.WINTER 2011Theme: Industrial Connections (Submission Deadline October 10, 2011)Water, wastewater and stormwater treatment/handling are not only the realm of municipalities. Industries of all types must address awide variety of wastewater treatment issues for direct discharge to waters of the state and for discharge into sanitary sewer systems(regulated via pretreatment permits). Many industries treat municipally supplied water prior to use in their products. Stormwater managementmay be the most innovative area of environmental engineering for both municipalities and industries today. These and manyother water quality concerns unite the municipal and industrial worlds in the NC AWWA-WEA, hence, the theme of this issue – industrialconnections. Articles about any aspect of industrial water or wastewater treatment, pretreatment program interactions with industrialcustomers, and industrial water use and beneficial reuse programs are welcome.SPRING 2012Theme: Water Sector Security (Submission Deadline January 2012)As threats to the water sector change and evolve, so must our preparations and responses. The low hanging fruit may have alreadybeen picked, but our work is not complete. Protecting the investments made in infrastructure, consumer confidence and our natural environmentalresources from manmade threats and natural disasters continues to be the heart of emergency preparedness and securitybasedrisk reduction programs. The next generation of security upgrades will take a more concerted effort. Is there support from EPAand the state? Losing interest in security and emergency preparedness is not an option. Integrating security into all facets of our planning(e.g., engineering, design, construction) and our daily work routine will develop the culture shift necessary to achieve security of ourwater resources and inspire consumer confidence in our abilities. The Communication Committee is requesting articles on any aspect ofemergency preparedness and security.Click Hereto return to Table of Contentswww.ncsafewater.org 95
