Coronado Backflow Testing, Installation & Repair

The Coronado Water Utility, which serves Coronado, has implemented rigorous standards for cross-connection control and backflow prevention to protect its potable water system. These regulations are based on the California Code of Regulations, Title 17 and Title 22, as well as the Cross-Connection Control Policy Handbook (CCCPH) adopted by the California State Water Resources Control Board (SWRCB). The Coronado Water Utility requires the installation and ongoing maintenance of approved backflow prevention assemblies (BPAs) at service connections where potential hazards to public health are identified. The program mandates the installation of backflow prevention devices at service connections where there is a risk of contaminating the public water supply. Property owners in Coronado are responsible for installing, testing, and maintaining backflow prevention devices, as well as for cooperating with inspections conducted by the Coronado Water Utility. Non-compliance with these regulations can lead to water service disconnection and financial penalties. The Coronado Water Utility’s backflow regulations require BPAs in the following situations: Coronado Property Irrigation Systems: Irrigation systems that use fertilizers, pesticides, reclaimed water, or other chemicals must have backflow prevention assemblies to prevent contamination of the potable water supply. Coronado Commercial and Industrial Properties: Facilities involving hazardous materials, chemicals, pressurized systems, or other potential contaminants must install approved backflow prevention assemblies to protect the potable water system. Coronado Property Fire Protection Systems: Fire suppression systems, such as sprinklers and fire hydrants, must be equipped with backflow prevention devices to ensure that stagnant or treated water does not flow back into the drinking water supply. Coronado Property Auxiliary Water Sources: Properties using private wells, cisterns, or rainwater harvesting systems must install backflow prevention assemblies to prevent cross-contamination with the public water supply. Failure to install a required backflow prevention assembly can result in water service disconnection by the Coronado Water Utility until compliance is achieved. To ensure the continued safety of Coronado’s drinking water, the following backflow testing and maintenance protocols are enforced by the Coronado Water Utility: Coronado Annual Backflow Testing: All backflow prevention assemblies must be tested annually by a certified backflow tester to ensure that they are functioning properly and effectively protecting the potable water system.

Coronado Post-Installation or Repair Backflow Testing: Any new installation, relocation, or repair of a backflow prevention device must be immediately tested to verify that it is functioning as required. Coronado Backflow Record Keeping: Test results must be submitted to the Coronado Water Utility for compliance tracking. These results can be submitted electronically through the Backflow Test Management System (BTMS) or via the appropriate forms provided by the Utility. Coronado Approved Backflow Devices: Only backflow prevention assemblies approved by recognized testing agencies, such as the University of Southern California’s Foundation for Cross-Connection Control and Hydraulic Research (USC-FCCCHR), may be used in Coronado. Coronado Certified Backflow Testers: Testing must be performed by certified backflow testers who are registered with the Coronado Water Utility. Testers must hold certification from the American Water Works Association (AWWA) or an equivalent certifying body. Failure to comply with Coronado’s backflow testing and maintenance requirements may result in penalties or suspension of water service until compliance is achieved.
