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 surveys are conducted to evaluate any potential hazards that may exist for:
- New properties
- Change of ownership in properties
Cross-Connection also oversees the annual testing and maintenance of currently installed backflow prevention assemblies.
East Valley Water District (EVWD) requires the annual testing and maintenance of all currently installed backflow devices. Click on the Annual Testing tab below to learn more annual backflow testing.
East Valley Water District (EVWD) requires the annual testing and maintenance of all currently installed backflow devices. Properly functioning backflow devices play an important part in protecting our drinking water system. State and local guidelines listed in Title 22 of the Administrative Code require that they be tested once a year by a certified tester. Testing shall be completed by a San Bernardino County certified tester in accordance with EVWD Ordinance 395.
For additional information regarding this program, please contact Water Quality at (909) 806-4222 or email email@example.com.
Evaluating Potential Hazards
Surveys play an important role in maintaining effective Cross-Connection Control Programs. Surveys are conducted on new and change of ownership properties to evaluate any potential hazards that may exist. Potential hazards identified are then evaluated for their degree of hazard before a determination can be made as to what type of backflow protection should be installed to protect the water system.
Forms and Applications
Backflow devices must be tested by certified backflow testers. A partial list of testers (PDF) 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.
