City of Hawthorne
Cal Water began operating the City of Hawthorne water system in 1996, when we entered into a 15-year lease agreement with the city. We were selected again by the City of Hawthorne in 2012 to operate the system for another 15-year term. Water is supplied to Hawthorne customers from one groundwater well and with purchased surface water obtained by the Metropolitan Water District of Southern California (MWD) from the Colorado River and the State Water Project in northern California. The Hawthorne system is comprised of one groundwater well, two MWD connections, six reservoirs, and four booster pump stations. Cal Water proactively maintains and upgrades our facilities to provide a reliable, high-quality supply.
