Backflow and Cross-Connection Prevention

PCWA works diligently to deliver safe and reliable drinking water to its customers. This effort begins with protecting our water supply sources and continues through the entire conveyance, treatment and distribution process until the water reaches the meter. The prevention of backflow into the public water supply is an integral part of ensuring safe drinking water.

Why We Administer A Backflow Prevention Program

In accordance with the requirements of the California Administrative code, Title 17, Chapter V, Sections 7583-7605, PCWA requires backflow protection on any treated water service with the potential for contamination of the public water supply.

Treated Water Connections Requiring Backflow Prevention Devices

  • Residential connections with a secondary source of non-potable water such as wells, ponds, springs, untreated irrigation water, and other waterways
  • All commercial connections
  • All landscape connections
  • All fireline connections
  • Any other conditions as determined by PCWA

Compliance Requirements - How to Remain Compliant

After the initial installation inspection and backflow prevention device testing by PCWA staff, customer must:

  • Maintain the privately-owned backflow prevention device
  • Submit annual test results to PCWA - PCWA will mail an annual test reminder letter, test form, and list of certified testers
