Cross Connection Control Program

Last updated Apr. 05, 2018 - 3:29 pm

The Cross Connection Program is responsible for ensuring potable water provided by the City remains safe throughout the water distribution system and is protected from “backflow events.” (an undesirable reversal of potentially contaminated water from a customer to the City’s system.) This protection is achieved through the installation of backflow control devices and assemblies on the customers’ side of the meter. For most residential customers, backflow protection is provided by a dual check device in the meter box. For other services with higher risk, testable backflow assemblies are installed and required by Raleigh City Code to be tested by a Certified Tester. The results of the test are submitted to our web based system, Brycer-The Compliance EngineTM.

Failing to adequately prevent or control backflow events could have significant negative health and economic impacts, as evidenced by the Corpus Christi, TX incident in December 2016.

Disconnection of Non-compliant Landscape Irrigation Meters Begins August 7, 2017

On Aug. 7, 2017, the Public Utilities Department began disconnecting the irrigation meters of residential and commercial customers whose irrigation backflow assemblies have been non-compliant for more than 360 days. Non-compliant irrigation customers were notified via email or by mail in 2016 and 2017, with many customers also receiving a phone call from our contractor. In June 2017, a final notice was hand delivered to non-compliant irrigation customers.

The disconnection process was completed in phases during August and September of 2017 and coordinated to prevent impacting normal meter reading schedules. Non-compliant customers were given detailed information (see attachments) on how to bring their service into compliance once the disconnection process has started. Our Cross Connection and Customer Care and Billing Customer Service Representatives are prepared to answer calls and assist customers with questions. If you receive a call from a citizen concerning this matter, you may direct them to the Cross Connection Staff at 919-996-2747 or

Licensed Inspection Service Providers Required to Register with the City

The City of Raleigh's Office of the Fire Marshal and the Public Utilities Department Cross Connection Program have instituted a new process for service providers who inspect and test fire protection and containment backflow assemblies. Effective Nov. 1, 2015 all compliant & non-compliant fire protection systems and containment backflow assembly test reports are required to be sent to The City of Raleigh electronically by your respective organization via The Compliance Engine's online system at

The City of Raleigh is dedicated to delivering 100 percent compliance with our adopted Fire and Cross Connection Codes. This web based service will aggregate, track and streamline the collection of systems compliance data by providing the property owners with timely notification of their testing requirements, and affording the City the ability to better mitigate the risk in our community by improving public safety to our citizens.

All service providers licensed to inspect or test fire protection systems and/or backflow assemblies within the City of Raleigh are required to register and submit all test and inspection reports via The Compliance Engine per Raleigh City Code Article D-Water Quality Protection, Part 5 Chapter 2 Article B-Fire Prevention and Protection Ordinance. All reports must be submitted in accordance with the testing schedule and requirements outlined in Public Utilities Handbook Appendix A: Guidelines and Requirements for the Cross Connection Program.

Testing Schedule:

Domestic/Fire Containment Assembly Testing Schedule:

Commercial & Residential Irrigation Testing Schedule
All residential irrigation containment assemblies are to be tested by July 1 every three years. Containment assemblies on commercial irrigation systems are to be tested annually by July 1. Testing of containment assemblies shall be conducted by a certified tester at the customer's expense. The owner shall cause such maintenance or repairs to be made, rendering the containment assembly fully operational. Additional testing and maintenance requirements may be requested or imposed as determined by the Raleigh Director of Public Utilities or his designee. It is the owner's responsibility to keep a complete, written record of any repairs and testing of the containment assembly for at least three years.


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

Owners of a facility containing a cross-connection that does not pose an imminent threat to the public water supply and who wish to apply for extension of time for compliance not to exceed one year from the date of the original notice issued pursuant to 8-2151 of the Raleigh City Code must proved the Cross Connection Coordinator in writing the following:

Irrigation Testing

Check Your Irrigation System in Spring
When Spring arrives and freezing temperatures cease, many customers will begin to turn on irrigation systems and start watering again. Many water customers restart their irrigation systems by reinstalling the backflow assembly or hiring an irrigation contractor to perform this service for them. However, when you do so, you should take a few very important steps to make sure you do not damage pipes or irrigation components. Irrigation systems that are exposed to freezing temperatures can have busted valves and leaks. It is always best to hire a professional contractor to ensure your system is up and running with ease and efficiency. It is also an excellent opportunity to set the system controller for 'minimum' use. Healthy turf needs half the amount of irrigation most people use. Less frequent, but deep watering grows strong roots. Please reduce your use and use water responsibly. For more information or to verify backflow information you can email us or call 919-996-2742.
