CROSS-CONNECTION CONTROL PROGRAM
You may have received letters from the Company with regard to backflow prevention assembly testing for your irrigation system. The Company continues to implement our cross-connection control program. These actions are in response to the Washington Department of Health (DOH) regulations requiring public water systems to develop and implement a cross-connection control program to protect the public water system’s distribution system from possible contamination that might occur within any given property.
The program seeks to reduce the risk of possible contamination into the water system due to water system pressure loss or the presence of a greater pressure on the customer side of the water meter. These risks are reduced by the installation and annual testing of DOH approved backflow prevention assemblies that use a combination of multiple spring loaded check valves to prevent possible backflow. The Company’s program assesses risks; with prioritization based on the potential health hazard should a backflow occur. The Company is required to annually complete and submit to DOH a report on the progress and results of the cross-connection control program.
