Backflow Prevention

Cross-Connection Control

East Valley Water District currently maintains a Cross-Connection Control program under Title 17 of the State of California Administrative Code by conducting site surveys and inspections of customers’ properties to determine if any potential hazards exist that would require the need of backflow protection.

Cross-Connection also oversees the annual testing and maintenance of currently installed backflow prevention assemblies.

Backflow Prevention

East Valley Water District (EVWD) requires the annual testing and maintenance of all currently installed backflow devices. Beginning April 3, 2017, EVWD will be offering backflow device testing for only $60 per year, a service that can be prorated on your account at $5 per month. To participate in the program, complete a Backflow Testing Application. You may email the application or fax it to (909) 806-4228. Applications may also be dropped off at our offices located at: 31111 Greenspot Road, Highland, CA 92346. For more information, please contact Water Quality at (909) 806-4222.

Backflow devices must be tested by certified backflow testers. A partial list of testers is available at the link below if you prefer a third-party company test your device.  All backflow test forms are recorded and filed by district personnel following our testing or upon receiving documentation of testing from a certified backflow tester.
