Cross-Connection Control Specialist and Backflow Prevention Assembly Tester Services for Cross-Connection Control Program Support

On December 19, 2023, the State Water Resource Control Board (SWRCB) adopted the Cross-Connection Control Policy Handbook (CCCPH). The CCCPH became effective on July 1, 2024, and replaced Title 17, the original statute governing cross-connection controls, on January 1, 2025. The purpose of the CCCPH is the protection of public health through the establishment of standards to protect the public water system's potable distribution system through the prevention of any potential backflow or back-siphonage of water from end-user sources back into the potable distribution system. The Agency falls under the CCCPH definition of a Public Water System and is subject to the CCCPH requirements. In order to provide a safe and reliable supply of water for the Tri-Valley area, the Agency submitted a plan in compliance with all the elements to the SWRCB on July 1, 2025. This plan may require revisions if requested by the SWRCB. The Agency currently has twenty air gaps and ninety-one backflow prevention assemblies in its water system. The Agency owns all backflow prevention devices within its facilities. The Agency's retail customers are responsible for managing their own cross-connection control programs. The Agency has water supply contracts with its direct customers that allow access and testing of all backflow prevention devices.
