AppendicesAppendix IGaining AccessConsent to enter other properties for drainage works may be critical foryour development to proceed so it should be given due consideration.The first meeting with the affected landowner(s) is very important andthe approach must be highly professional.NegotiationIn all cases Auckland City Council requires the developer to try and negotiateprivately with the affected landowner(s) and come to a mutual agreement. Thesuccess of a private negotiation greatly depends on prior preparation and on howthe affected landowner is approached. Inadequate preparation and poor approachcould lead to great expense in time and costs for the customer.Local Government ActsSection 460 of Local Government Act 1974 and Section 181 of Local GovernmentAct 2002 set out procedures for Auckland City Council to access private land tocarry out required drainage works where a landowner has refused to give consent.These processes should only be considered as an absolute last resort.Applications in term of these provisions can be made to Auckland CityEnvironments (ACE) in the appropriate form with a deposit. Note that the fee is adeposit only and further costs may be incurred. All costs towards processingapplications are to be met by the applicant.The above process could be a lengthy and potentially expensive one. There couldalso be objections and appeals against Auckland City Council’s determination. It isimportant to note that the final outcome of this process may not be infavour of the applicant. It is therefore highly recommended that in thefirst instance, all care be taken while approaching the affectedlandowner(s) to request their consent.Auckland City CouncilAuckland City Council may accept the application only when it is satisfied that theapplicant has tried all approaches and is not able to gain consent. To enableAuckland City Council to assist in any way, the applicant will need to provideevidence that s/he has:• Engaged a drainage expert to investigate and consider all options andalternative routes;• Presented clear and precise drawings to the affected landowner(s) forconsideration (ensure the drawings include items that could be valuable tothe affected landowner for example, patio, garden, trees);• Considered the most appropriate and least destructive method for theinstallation of the proposed drain;• Discussed the timeframe including the completion of all reinstatementworks;• Offered a cash bond, if required, to the affected landowner(s)’ solicitor untilcompletion of works;• Listened and understood to the affected landowner(s)’ concerns;• Considered the affected landowner(s)’ concerns and tried to find suitablesolutions.Do it once: Do it rightDevelopment and Connection Standards – Water, Wastewater and Stormwater Design and Policy Manual for Auckland City Isthmus, 4 th Edition Mar 2009 Page I-1Copyright © Mar 2009

AppendicesAppendix K(cont)Levelling and Sounding DatumsDefinitions and Explanatory NotesAuckland Harbour Board, July 1970The period over which tide gauge records should be analysed is ideally the Metonic Cycleapproximation of 19 years. The mean values for high and low water at Auckland have been thusobtained but the levels at Onehunga are for the period since September 1960 when the new tidegauge was installed.Mean Sea Level‘The average value of the sea at all states of tide’ (Ref 1). The value of MSL Auckland isestablished by the Surveyor General New Zealand from calculations by his Department from tidegauge records. The value of MSL Onehunga has been obtained by averaging 4 results from theAdmiralty Semi-Graphic method of Tidal Analysis (Ref 5).Mean Tide Level‘The average value of the high and low waters from the Tide Gauge’ (Ref 1).Mean Low Water Springs and Mean High Water SpringsThe height of mean high water springs is the average throughout a year when the averagemaximum declination of the moon is 23½° of the heights of two successive high waters duringthose periods of 24 hours. (Approximately once a fortnight) when the range of the tide isgreatest. The height of mean low water springs is the average height obtained by the twosuccessive low waters during the same periods.Mean High Water Neaps and Mean Low Water NeapsAs above but substituting ‘least’ for ‘greatest’.Mean High Water and Mean Low Water‘The average levels of high and low water respectively over a lengthy period’ (Ref. 8). The currentvalues of MHW and MLW have been obtained by averaging all the tidal high and tidal low levelsover the most recent 19-year period. The values thus obtained are applicable to the central yearof the period. A further process revealed a trend over the whole period which, when applied,gives the present adopted values of the year specified. This process will be repeated in 1971 andthe values adjusted if any significant change in trend has taken place.Sounding DatumThe level to which Soundings on a plan or chart are referred. The Auckland Harbour BoardSounding Datum is coincident with the Navy Department Chart Datum and is at a level belowwhich a low tide rarely falls.HWOST and LWOSTThese terms are now obsolete.HWST and LWSTThese terms are now obsolete.Development and Connection Standards – Water, Wastewater and Stormwater Design and Policy Manual for Auckland City Isthmus, 4 th Edition Mar 2009 Page K-4Copyright © Mar 2009

AppendicesAppendix OIntegrated Catchment StudyThe Integrated Catchment Study (ICS) was a four-year study to develop acomprehensive understanding of the Auckland Isthmus drainage systems andreceiving environments, and to develop decision-making tools.The study was performed in three stages: (1) data capture, (2) catchmentanalysis (model development and system performance) and (3) options analysisand reporting. Computer models were developed for the (a) integratedwastewater, combined, and stormwater surface and piped networks; (b)groundwater aquifers and (c) near shore Waitemata and Manukau harbours.The stage 3 reports cover a range of issues including identification of predicted 50-Year Flood Plains and overland flow paths, combined and wastewater systemperformance and Ground Aquifer performance. These Reports and Maps should beconsulted for all development in the area they cover especially where floodinghazards or Wastewater surcharging exist or are suspected.

From catchmentlocation and boundary, to pipe system network, street crosssections and model results.1993 The main objective of the CBD Catchment Management Plan is toprovide a comprehensive management strategy for the foulwaterand stormwater drainage systems in the Auckland Central BusinessDistrict.This plan is one in a series being developed to manage the city'sdrainage system into the next century and to identify the mosteffective drainage strategy to meet current and future developmentneeds within the 170 hectare catchment.1999 City Design was engaged to manage the investigation of privatedrainage of individual properties in the Central Business DistrictCatchment (CBD). The objective of this investigation was to checkand confirm if the private drainage is separated or combined; todetermine if the private stormwater drain enters into a separatedor combined public drain; and to provide a proposed design planfor the separation of confirmed combined private drain. Theinvestigation also provided a cost-effective preference to separatewastewater.2000 This report reviews the public wastewater drainage system of theexisting CBD catchment to establish whether further separation ofthe remaining combined public wastewater drainage system isrequired. In terms of an integrated study, the report reviewswhether the remaining portions of the combined wastewaterdrainage system are of adequate capacity to contain both the dryand wet weather flows, for the areas identified previously asrequiring separation, without causing an impact.The study covers the southern half of the CBD catchment - theCTYAF catchment (90 hectares).2002 This report presents the Comprehensive Catchment ManagementPlan (CMP) for the Auckland Central Business District (CBD).

The Motions catchment is located withinCentral Auckland, stretching out to Point Chevalier, and covering anarea of 390 hectares, or 3% of the whole isthmus area. TheAuckland Zoo is contained within this catchment.This document contains the first addendum to the above CMP.1996 This report supports an application for a Resource Consent fordischarges form Auckland Zoo to Motions Creek, and includes anenvironmental impact assessment by NIWA.This report is the first addendum to the Auckland Zoo DrainageInvestigation report prepared by Development Consultancy inAugust 1994. Issue A of this report is to be reviewed by theAuckland Zoo, Avondale/Mt Albert/Western Bays Area Office andARC prior to Council approval and public consultation.2001 This report is intended to provide supporting information to anapplication for a change or cancellation of consent conditions forthe Motions Creek Catchment stormwater discharge permit, which isbeing sought pursuant to Section 127 of the Resource ManagementAct, 1991(RMA). The application is made by City Design on behalfof Auckland City Council.1992 This Foulwater Management Plan sets out the available informationon known problems within the Motions foulwater drainage systemand provides information required to control the effects of futuredevelopment on the catchment.2002 This report is a follow up to the report for City Design entitled"Motions Creek Stormwater Pipe - Hydraulic Modelling Project." Thepurpose of the work rendered in this report is to verify anddocument that by exploiting the storage capacity in the systemsettable solids can be retained. The idea is to release thestormwater from the downstream pipe at a restricted rate thuslowering flow velocities in the downstream part of the system somuch that the main part of the settable solids will deposit.The calculations are verified applying historical rainfall records fromthe period 19989-1999 taking 1996 as a typical year. Additionally,design storm events with return periods of 10 and 100 years areused.2002 This report provides the following information for assessing theenvironmental impact of separation works in sub catchments B, K,and C in the Motions catchment.In addition, the report contains an appended Project STORMassessment and the original MOUSE model outputs for assessingcontaminant loads (as supplied by Sinclair Knight Merz).2003 The purpose of this report is to produce a preliminary drainageseparation plan for Basque Park, as the catchment is currentlyserviced by a combined drainage system.. The preliminarySeparation Plan will enable community planning to proceed withdevelopment of the park taking into account the future separationdrainage proposals.2003 A desktop study has been undertaken in the Motions part Sub-Catchment A "Canada St sub catchment" to establish options forseparation including preliminary locations for new public wastewaterand stormwater lines and identifying the private drainage status.The separation of this particular sub-catchment area has become apriority due to the poor condition of the existing 750mm diametercombined brick culvert in Canada Street and East Street, wheredislodged bricks are causing blockages of the wastewater systemand overflow into the 1200mm diameter SW downstream.2003 A desktop study has been undertaken in the Motions part Sub-Catchment D & E to establish options for separation includingpreliminary locations for new public wastewater and stormwaterlines and identifying the private drainage status. Includesassessment of stormwater/ combined capacity and identifiesupgrades required.Development and Connection Standards – Water, Wastewater and Stormwater Design and Policy Manual for Auckland City Isthmus, 4 th Edition Mar 2009 Page O-10Copyright © Mar 2009

AppendicesAppendix TTesting Requirements for New Public AssetsDrainage Completion TestsNewly constructed public wastewater and stormwater will not be accepted ascompleted until it has been tested in accordance with the following TestingProcedures to the satisfaction of a Development Engineering (DE) or MetrowaterEngineer.The test(s) used in any case will be at the discretion of DE or Metrowater Engineer,and must:• Be organised and paid for by the developer;• Be notified to the DE or Metrowater Engineer at least two working days inadvance;• Use calibrated equipment supplied by the developer;• Be recorded (including the date and time) with representatives from allparties receiving a copy of the results;• Take place once the As-Builts have been submitted and with the As-Builtson-site;• Take place once pipe trenches are backfilled;• In the event of a test failing, be repeated to the DE or MetrowaterEngineer’s satisfaction.No connection can be made between new and existing reticulation untilexplicitly approved by the Metrowater Engineer.Pre-Test Condition and Procedure• Testing will not be carried out until all concrete has attained sufficientstrength to not be damaged by the test;• All Y-junctions and fittings must be sealed;• The specified test pressure is to be that at the lowest point in the section,and if the pressure is not measured at that point, the relevant correctionmust be made;• Where a water test is carried out, all air must be removed from the teststation.Visual TestsExcept for pipes shown on the approved plans as being curved, no pipe length willbe accepted unless a full bore can be seen all through it and it is clean and free ofdebris.Test EquipmentFor pressure tests of pipelines (such as rising mains), use an approved pressurepump with high pressure/low flow at a steady rate without shock loading, andconnect the pump delivery to any convenient and approved water source (wherewater is to be used). The Contractor must use an approved pressure recorder,capable of producing a hard-copy print-out of the recorded pressure. All hard-copyprint-outs must be forwarded to the Engineer following the successful pressuretest. Alternatively, a conventional pressure gauge may be used provided it can beread to + 10kPa or as otherwise appropriate for the test, and has a calibrationcertificate from a registered IANZ Laboratory less then one year old.Development and Connection Standards – Water, Wastewater and Stormwater Design and Policy Manual for Auckland City Isthmus, 4 th Edition Mar 2009 Page T-1Copyright © Mar 2009

AppendicesAppendix T(cont)Testing Requirements for New Public AssetsTesting Procedures• Water TestA water test in accordance with NZS 4404:2004 must be used for all risingand pressure mains unless otherwise specified.• Low Pressure Air TestA low-pressure air test in accordance with NZS 4404:2004 must be used forall gravity mains unless otherwise specified.• Pipe Infiltration TestInfiltration flow must be measured for all pipes after all private drainageservice connections are completed. This flow cannot exceed 25ml/hr/mmpipe diameter/1000 metres pipe length.• Manhole Infiltration TestThis test is to be carried out for all manholes after backfilling but beforesurface sealing or reinstatement. A small bund or depression must beformed around the manhole, and water and approved dye poured in untilthe ground is saturated. The manhole will be deemed to have passed thetest if there is no leakage into the manhole from any source.• Smoke TestA smoke test will not be used as a sole test but will be used in conjunctionwith either the water test or the air test when assistance is required indetermining the position of faults. All branches and openings in thepipeline must be sealed. Smoke will be injected from a suitable smokemakingmachine at a pressure of 100mm of water head – a pressure thatwill be maintained while the pipe is being inspected. All detectable leaksmust be repaired by the Contractor and the procedure repeated until nodiscernible emission of smoke occurs. After compliance with this test, thepipeline must pass either a water test or air test as specified above beforeacceptance.Development and Connection Standards – Water, Wastewater and Stormwater Design and Policy Manual for Auckland City Isthmus, 4 th Edition Mar 2009 Page T-2Copyright © Mar 2009
