Formed in 1950, the United Water Conservation District battles groundwater overdraft through a combination of aquifer recharge and providing alternative surface water supplies. The District owns Lake Piru and key facilities along the Santa Clara River that are used to manage groundwater supplies. The United Water Conservation District provides wholesale water delivery through three pipelines to various portions of the Oxnard Plain. One is the Oxnard/Hueneme system which serves the City of Oxnard, the Port Hueneme Water Agency (City of Port Hueneme, Channel Islands Beach CSD) and the Naval Base Ventura County (Point Mugu and the Construction Battalion Center). A second pipeline serves agricultural uses in the Oxnard Plain. The third system supplies water to the Pleasant Valley area located between Oxnard and Camarillo. United rates for non-agricultural uses are at least three times more than agricultural users are charged as required by the state water code.
