A cross connection is a connection between a drinking water supply and a source of pollution or contamination. The undesirable reversal of flow that may allow entry of pollutants and contaminants into the drinking water supply is called "backflow."


To ensure drinking water supplies are protected from contamination, Cross Connection Control Program staff inspect commercial facilities, industrial buildings, irrigation systems, and water distribution systems for proper installation and maintenance of backflow prevention assemblies. Additionally, staff monitor the installation, repair, and annual testing of over 16,000 backflow prevention assemblies installed on distribution systems operated by public water purveyors throughout the County.

Water users are responsible for the annual testing and maintenance of backflow prevention assemblies to ensure their proper operation.  Click here for a list of testers certified in Ventura County.
