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 />

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 />

18 11/06

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 />

II. TYPICAL BACKFLOW PREVENTION DEVICE INSTALLATION<br />

A. Once a Degree <strong>of</strong> Hazard has been determined and properly classified, remedial<br />

steps shall be taken to correct the condition or an approved backflow prevention<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 />

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 />

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 />
