CROSS CONNECTION CONTROL<br />
AND<br />
BACKFLOW PREVENTION<br />
INTRODUCTION<br />
Per Article 3, Paragraph 12 VAC 5-590-580 <strong>of</strong> the Virginia Department <strong>of</strong> Heath Waterworks<br />
Regulations, as a condition for the issuance, and continued use, <strong>of</strong> the Commonwealth <strong>of</strong><br />
Virginia Department <strong>of</strong> Health Waterworks Operation Permit (to treat raw water and distribute<br />
potable drinking water), the <strong>City</strong> <strong>of</strong> <strong>Richmond</strong> must establish and enforce a program <strong>of</strong> cross<br />
connection control and backflow prevention to protect and ensure that the water distribution<br />
system <strong>of</strong> the <strong>City</strong> <strong>of</strong> <strong>Richmond</strong> is pure and safe for public consumption. The purpose <strong>of</strong> the<br />
<strong>Cross</strong> <strong>Connection</strong> Control and Backflow Prevention Program (the Program) is to protect the<br />
<strong>City</strong>’s drinking water system from any cross connections made to or backflow entering the water<br />
distribution system and to protect the public health.<br />
The <strong>City</strong> <strong>of</strong> <strong>Richmond</strong> is responsible for providing potable water service to our customers in the<br />
<strong>City</strong> and surrounding municipalities. It is the <strong>City</strong>’s Department <strong>of</strong> Public Utilities (DPU)<br />
obligation to insure the health, safety and welfare <strong>of</strong> our customers by making a continuous<br />
effort to provide quality services. The focus <strong>of</strong> this document is to assure protection <strong>of</strong> water<br />
quality throughout the water distribution system and to our customers.<br />
The DPU and the consumer have a shared responsibility for water quality. The DPU’s<br />
responsibility is for the distribution system and water service up to and through the water meter.<br />
The consumer’s responsibility begins after the water meter and includes the service line and all<br />
the pipe, fittings and appliances beyond the meter. The <strong>City</strong> requires the Customer to install a<br />
service line backflow prevention device on each service line, on the Customer’s property near<br />
the property line, just after the meter and prior to pipes branching <strong>of</strong>f to different locations or<br />
uses within the property/site or the building. DPU is responsible for determining when, where<br />
and what type <strong>of</strong> backflow prevention must be installed on the service line, per the Waterworks<br />
Regulations (Article 3, paragraph 12 VAC 5-590-610).<br />
To maintain water quality, the DPU must identify potential cross connections and determine<br />
necessary protection measures. To aid in this, the <strong>Cross</strong> <strong>Connection</strong> Control and Backflow<br />
Prevention Program was adopted in 1984 and recently has been revised. The Program identifies<br />
those activities which pose a threat to the public potable (drinking) water supply through cross<br />
connections and backflow and outlines appropriate protective measures.<br />
The purpose <strong>of</strong> this manual is to:<br />
● Prevent backflow pollution or contamination <strong>of</strong> the water supply system by requiring<br />
the installation <strong>of</strong> an appropriate backflow prevention device or by backflow<br />
prevention by separation at the service connection,<br />
● Explain the criteria by which the <strong>City</strong> will determine the Degree <strong>of</strong> Hazard,<br />
● Define required backflow prevention assemblies or devices,<br />
4 11/06
<strong>City</strong> <strong>of</strong> <strong>Richmond</strong> <strong>Cross</strong> <strong>Connection</strong> Control and<br />
Backflow Prevention<br />
● Educate those who work with public water supplies, and<br />
● Encourage consumers to actively support and implement cross connection control for<br />
the purpose <strong>of</strong> protecting the public water supply.<br />
This manual is intended to address the requirements <strong>of</strong> the Water Purveyor (<strong>City</strong> <strong>of</strong><br />
<strong>Richmond</strong> DPU) and the public water system. Separate requirements may be required<br />
under the Plumbing Code.<br />

CROSS CONNECTION CONTROL<br />
AND<br />
BACKFLOW PREVENTION<br />
DEFINITIONS<br />
The term “Air-Gap Separation” shall mean the unobstructed physical separation through<br />
the free atmosphere between any pipe or faucet supplying water to a tank, plumbing<br />
fixture or other device. The physical separation shall be measured from the lowest<br />
opening <strong>of</strong> the pipe to the highest rim <strong>of</strong> the receptacle. An “approved air-gap<br />
separation” shall be a linear distance <strong>of</strong> at least two times the diameter <strong>of</strong> the supply pipe<br />
measured vertically above the rim <strong>of</strong> the vessel and the bottom <strong>of</strong> the discharge pipe.<br />
The minimum separation shall be two (2) inches in all cases.<br />
2. Approved<br />
The term “approved” means material, equipment, workmanship, process or method that<br />
has been accepted by the Uniform Statewide Building Code (BOCA International<br />
Plumbing Code) as suitable for the proposed use.<br />

4. Atmospheric Vacuum Breaker<br />
The term “Atmospheric vacuum breaker” (also known as the “non-pressure type vacuum<br />
breaker”) shall mean an assembly containing a float-check, a check to close the air inlet<br />
port. The flow <strong>of</strong> water into the body causes the float to close the air inlet port. When<br />
the flow <strong>of</strong> water stops the float falls and forms a check valve against backsiphonage and<br />
at the same time opens the air inlet port to allow air to enter and satisfy the vacuum. A<br />
shut<strong>of</strong>f immediately upstream may be an integral part <strong>of</strong> the assembly. An atmospheric<br />
vacuum breaker is designed to protect against a health hazard, (i.e. containment) under a<br />
backsiphonage condition only.<br />
5. Auxiliary Water System<br />
The term “auxiliary water system” shall mean any water system on or available to the<br />
premises other than the waterworks. These auxiliary water systems may include water<br />
from another purveyor’s waterworks or water from a source such as wells, lakes, or<br />
streams; or process fluids, or used water. They may be polluted or contaminated or<br />
objectionable, constitute a water source or system over which the water purveyor does<br />
not have control.<br />

cause health and adverse effects upon the waterworks.<br />
2. The BOCA International Plumbing Code only recognizes backflow prevention<br />
devices for either “high” or “low” Degrees <strong>of</strong> Hazard. For “high” Degree <strong>of</strong><br />
Hazard connections a reduced principal zone (RPZ) backflow preventer is<br />
required. For “low” Degree <strong>of</strong> Hazard connections a double check valve<br />
assembly (DCVA) backflow preventer is required.<br />
3. A “low” Degree <strong>of</strong> Hazard requires all <strong>of</strong> the water uses within a building or<br />
complex to have appropriate point <strong>of</strong> connection (POC) backflow prevention<br />
devices in working condition and not contain a “high” hazard use as defined in<br />
Table 4.2. Since the <strong>City</strong> <strong>of</strong> <strong>Richmond</strong> does not have the authority to inspect or to<br />
require maintenance on POC backflow devices, the <strong>City</strong> does not know that all <strong>of</strong><br />
the POC backflow devices are operating properly and the <strong>City</strong> assumes that at<br />
least one (1) POC device is malfunctioning. Therefore, all connections within the<br />
<strong>City</strong> are “high” Degree <strong>of</strong> Hazard connections. There are two (2) exceptions to<br />
this assumption:<br />
a. The <strong>City</strong> allows the use <strong>of</strong> DCVA backflow preventers on “low” Degree<br />
<strong>of</strong> Hazard fire service connections. A “low” Degree <strong>of</strong> Hazard fire service<br />
connection is any system with only a Siamese connection. A “high”<br />
Degree <strong>of</strong> Hazard fire service connection is:<br />
1) A system with pumper connections where corrosion inhibitors or<br />
other chemicals are added,<br />
2) All foamite plant installations,<br />
3) A system where an unapproved water supply is permanently<br />
connected to a fire hydrant,<br />
4) A system in which antifreeze is used,<br />
5) Auxiliary water supplies,<br />
6) A system with storage tanks,<br />
7) A “dry” system with compressed air.<br />
8) Complex fire systems where the <strong>City</strong> cannot verify the installation.<br />
9) Existing systems where the <strong>City</strong> cannot verify the installation.<br />
b. The <strong>City</strong> does not require the use <strong>of</strong> backflow prevention devices on single<br />
family residential connections that have only domestic use services<br />
(cooking, drinking, and toilet). Residences that have pools, hot tubs,<br />
17 11/06
<strong>City</strong> <strong>of</strong> <strong>Richmond</strong> <strong>Cross</strong> <strong>Connection</strong> Control and<br />
Backflow Prevention<br />
irrigation systems, a fire system, operate a business or a private well are<br />
considered “high” Degree <strong>of</strong> Hazard connections and require RPZ<br />
backflow preventers.<br />
1) Single family residences with separate domestic use and irrigation<br />
connections do not have to have a backflow preventer on the<br />
domestic connection as long as it does not conflict with paragraph<br />
III.A.3.b. The irrigation connection will require a backflow<br />
preventer in accordance with Part VI <strong>of</strong> this manual. Single family<br />
residences with a separate domestic use and fire service<br />
connections do not have to have a backflow preventer on the<br />
domestic connection. The fire service connection will require a<br />
backflow preventer in accordance with Part V <strong>of</strong> this manual.<br />
B. EXISTING CONNECTIONS ASSESSMENTS<br />
Assessments may be performed by questionnaire, interviews or on-site assessments. Interviews<br />
may be conducted on-site or by telephone at the discretion <strong>of</strong> the CCCS.<br />
1. Assessments by Questionnaire<br />
a. Annual questionnaires may be sent to each Customer.<br />
b. The results <strong>of</strong> the annual questionnaires will be reviewed by the CCCS.<br />
Based on the response to the questionnaires, cross connection control<br />
interviews will be scheduled and appropriate backflow prevention devices<br />
required to provide containment determined. No response to the<br />
questionnaire will prompt an on-site interview. Refusal <strong>of</strong> access for<br />
inspection or provision <strong>of</strong> pertinent information shall prompt the<br />
requirement to install a high hazard containment device. A high hazard<br />
device is required on all service containment except fire sprinkling which<br />
may require both.<br />
2. Assessment By Interview<br />
a. Interviews will follow a prepared questionnaire to assess the need for<br />
cross connection control by containment.<br />
b. Available information about the premises to be surveyed will be gathered<br />
prior to the interview.<br />
c. The reasons for cross connection control and backflow prevention as well<br />
as the degree <strong>of</strong> hazard determined will be explained to the customer or<br />
the customer’s representative.<br />
d. The questionnaire will cover the following topics:<br />

TABLE 4.2<br />
DETERMINATION OF DEGREE OF HAZARD<br />
Premises with one or more <strong>of</strong> the following conditions shall be rated at the corresponding Degree <strong>of</strong> Hazard<br />
HIGH HAZARD<br />
LOW HAZARD<br />
The contaminant would be toxic, poisonous, noxious or unhealthy<br />
A health hazard would exist.<br />
A probability exists <strong>of</strong> a backflow occurrence either by back pressure or by backsiphonage<br />
The containment would disrupt the service <strong>of</strong> piped water for drinking or domestic purposes.<br />
Examples – Sewage, used water, non-potable water, auxiliary water systems, toxic or hazardous<br />
chemicals, etc.<br />
The contaminant would only degrade the quality <strong>of</strong> the water aesthetically<br />
A health hazard would not exist.<br />
A low probability exists <strong>of</strong> the occurrence <strong>of</strong> a backflow primarily by backsiphonage<br />
The contaminant would not disrupt the service <strong>of</strong> piped water<br />
Examples – Food stuffs, non-toxic chemicals, non-hazardous chemicals, etc.<br />

D. The RPZ backflow preventer will be installed as near to the property line as<br />
possible (See Standard Drawings FIRE-A and HI-HAZ). Maintenance<br />
responsibility <strong>of</strong> the DPU will end immediately preceding the inlet gate valve <strong>of</strong><br />
the assembly.<br />
II. PLAN REVIEW AND APPROVAL<br />
A. The CCCS will perform plan review <strong>of</strong> the proposed water line extension up to<br />
the first approved gate valve located on the inlet side <strong>of</strong> the DCVA and the plan<br />
review <strong>of</strong> the assembly as it relates to the backflow device, etc. For fire service<br />
laterals, a gate valve shall be installed on the tee at the main. In all cases the<br />
engineer shall provide details illustrating what type <strong>of</strong> anchoring will be used on<br />
the inlet side <strong>of</strong> the assembly, so that the approved valve (inlet side) <strong>of</strong> the DCVA<br />
will not blow <strong>of</strong>f when the DCVA is removed.<br />
B. The CCC will review the plan for the location <strong>of</strong> the backflow prevention device<br />
at such time as a utilities plan is submitted to the DPU. Separate plans for the<br />
location <strong>of</strong> the backflow prevention device shall be submitted to the CCC.<br />
C. An auxiliary mechanical permit issued by the Building Inspector’s Office, along<br />
with four (4) sets <strong>of</strong> plans, is required for the work from the vault to the building<br />
and shall be applied for by the installing contractor from the Building Inspector’s<br />
Office and plans submitted to and reviewed by the Fire Department.<br />
III. DESIGN<br />
A. The backflow device shall be located at or as near to the property line as possible.<br />
as shown on the standard drawings, and out <strong>of</strong> the main flow <strong>of</strong> traffic.<br />
a. The vault location will be reviewed by the CCCS for optimum placement.<br />
The review <strong>of</strong> the site plan will not be a detailed review <strong>of</strong> the water and<br />
sewer design when it involves the relocation and/or extension <strong>of</strong> the <strong>City</strong>’s<br />
system. However, the site plan must reflect the approved water and sewer<br />
design and show the exact location <strong>of</strong> the existing facilities. Therefore, it<br />
is important that the Engineer submit utilities plans directly to the DPU at<br />
the same time or as near that time to avoid unnecessary delays in the<br />
approval <strong>of</strong> the site plan and release <strong>of</strong> the building permit.<br />
b. Installation <strong>of</strong> DCVA other than at the property line must be approved by<br />
the CCCS.<br />
B. The backflow device shall be designed and constructed in accordance with the<br />
<strong>City</strong>’s Standard Details.<br />
C. Under any circumstances where a siamese connection is required, it will be<br />
installed on the outlet side <strong>of</strong> the DCVA/RPZ.<br />

fire line service must have this reflected on the Site Plan and the Utility Plan (the<br />
Engineer is required to submit for review and approval a separate Utility Plan to<br />
the DPU) indicating the service size required for the fire demand, the size water<br />
meter and the service size required for the domestic use. The applicant must<br />
indicate clearly on the water meter sizing form the desire to separate the fire<br />
service, otherwise, the water meter and appurtenances will be installed without<br />
regard to the fire service and the applicant will be subject to additional expense to<br />
correct the installation.<br />
E. The installation <strong>of</strong> 2-inch and smaller fire line and water meter service line and<br />
box must comply with the requirements in this section and the applicable details<br />
in Part IX – Standard Drawings.<br />
F. Where an applicant cannot accomplish combining the fire/domestic services<br />
and/or a separate fire line is needed where a water meter service already exists, all<br />
service line backflow prevention work must be performed in accordance with the<br />
device installer requirements in Section III.<br />
G. Fire systems with an in-line system booster pump shall have a low pressure<br />
regulator or cut-<strong>of</strong>f device shall be installed to prevent the inlet pressure from<br />
dropping below 10 psi (VDH 12VAC 5-590-610 D).<br />
