Certified Testers Update:
The City of Raleigh's Cross Connection Program can only enforce the testing of containment backflow assemblies. Therefore, beginning October 1, 2014, all domestic and irrigation backflow test reports are required to have the meter number of the water service they contain. Furthermore, as of October 1, 2014, we will no longer accept faxed or mailed test reports. All test reports must be submitted online.

2015 Surveys:
Throughout 2015, the Public Utilities Department will be conducting surveys at commercial and residential facilities to verify there are approved backflow assemblies containing domestic, irrigation, and fire sprinkler services.
Your facility may be found to not have the proper backflow protection, and a corrective action notice will be given to you to install an approved backflow.

Because of the surveys conducted by the Public Utilities Department in 2015, testing notices will not be sent to our water customers that are required to annually or triennially test their containment backflow assemblies. Testing notices are a courtesy provided to our water customers and lack of a notice does not eliminate the annual or triennially testing requirement. For more information you may email us or call 919-996-2742.

Corrective Action Notice

Requirement to Install:
In the City of Raleigh's Public Utilities Cross Connection Ordinance, Section 8-2147 & 8-2148 requires every residential and commercial water consumer to have a containment device installed at each point of separation between the public water supply and a private service or private distribution system or at the point of metering. For residential customers without an irrigation or fire sprinkler system or any hazard listed in Sec. 8-2147, this containment is accomplished by the dual check that is installed on the meter yoke. All other services are required to be contained by the installation of an approved Reduced Pressure Zone (RPZ) backflow assembly or Double Check Valve Assembly (DCVA) after the meter or point of separation. Backflow protection is required for all services and facilites that are not exempted because of the age of the facility.

What do I do if I received a Corrective Action Notice?
If a site survey was conducted by our Cross Connection Program at your facility and you were found non complaint, you will have 90 days to comply with the Corrective Action Notice you were given. If you feel this notice was given in error, you may request an exemption to install an approved containment backflow assembly by submitting a Backflow Assessment Form.
Backflow Assessment Form

If you find that your facility currently has the proper containment backflow assembly, you must submit the following documentation:
1. Backflow Verification Form
2. Current passing operational test for the approved containment backflow assembly

Irrigation Testing

Winterized Irrigation Systems
Each Spring, many water customers restart their irrigation systems by reinstalling the backflow assembly or hiring an irrigation contractor to perform this service for them. This year, we are asking our water customers to make note of the serial number, make and model of the backflow assembly that is installed on their system. If they hire an irrigation contractor to restart their irrigation system, we are asking the water customer to make sure the contractor reinstalls the same backflow used the previous season. A backflow serial number that does not match our database will be considered a replacement backflow and may require a permit number to be given on the report. (Contact local Inspections Department for requirements) For more information or to verify backflow information, you can email us or call 919-996-2742.
