Cross-Connection Control Program
In order to protect the City of West Richland water supply, the City established a Cross-Connection Control Program through Ordinance 7-08, codified in the West Richland Municipal Code 13.50 in accordance with the Washington Administrative Code (WAC) 246-290-490.
These state and local laws require the City to have all premises surveyed by a licensed cross-connection specialist to assess any hazards that may be present. We may protect the City water supply by having a premise owner install a backflow assembly. In most cases, we rely on "in-premise fixture protection", as we do on your underground sprinkler system. In-premise fixture protection protects the water users as well as the City water system. In rare instances, we use "premise isolation" to completely separate the water system from any possible cross-connections. Premise isolation protects the City water system but not the water users in that premise and is used when frequent plumbing changes may endanger the water system.
- What is a cross-connection?
- I received a letter from the City notifying me my backflow assembly needs to be tested. Is there a list of certified testers?
- What is considered a potential hazard?
- I want to connect my underground irrigation system to the City potable water in addition to the CID or the KID, what is the proper way to connect to both systems?
- I am installing an underground sprinkler system utilizing only City potable water. How do I properly connect my underground sprinkler system to the City's potable water?
