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 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.

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.
