Cross Connection Control A cross connection is the point at which any unwanted domestic, commercial, or industrial water from a customer’s system can flow back into the City’s water distribution system. This unwanted flow is called backflow. Backflow can be caused by numerous conditions but is typically due to the pressure of a customer’s water system exceeding that of the City’s water distribution system.
Backflow Prevention Device Assemblies Backflow prevention device assemblies prevent the backflow of potentially contaminated or polluted water into the City’s distribution system by using “-check-” or “-anti-siphon-” valves.
Oversight In order to protect the City’s water distribution system, the La Palma Water Division oversees the installation, testing and maintenance of the approximately 225 backflow prevention device assemblies currently installed in La Palma.
Cooperative Efforts Although it is the customer’s responsibility to maintain backflow prevention device assemblies, La Palma Water Division staff works closely with the Orange County Health Care Agency (OCHCA), the City’s Community Development Department, consultants and contractors to assure that proper backflow prevention device assemblies are installed and are tested annually.
Annual Maintenance and Testing Process The California Code of Regulations and the City of La Palma require water users at locations where backflow prevention devices are installed to maintain their assemblies “in a continuous state of good repair and test the devices annually."
To ensure your backflow device remains in good operating order and in compliance, follow these simple steps:
Have the necessary repairs made to backflow prevention device and complete the report form
Mail a copy of the completed test report to: Orange Health Care Agency 1241 E. Dyer Rd, Suite 120 Santa Ana, CA 92705-5611
Mail the original completed report to: City of La Palma Public Works Department 7821 Walker St. La Palma, CA 90623-1771
Tester Requirements The annual tests must be performed by a backflow device tester that is certified by the OCHCA. Therefore, you may only use a tester that is currently on the OCHCA approved testers list.
