Our Water Systems
Dominguez
Cal Water has provided high-quality water utility services in the Dominguez area since 2000. Cal Water serves most of the City of Carson and portions of Long Beach, Torrance, Compton, and unincorporated areas in Los Angeles County. To meet our customers’ needs, we use a combination of local groundwater and surface water purchased from Metropolitan Water District of Southern California (MWD), which is imported from the Colorado River and the State Water Project in northern California. The Dominguez water system currently includes 374 miles of pipeline, nine active wells, 12 storage tanks, and seven MWD connections.
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.
Palos Verdes Peninsula
Cal Water has provided high-quality water utility services in the Palos Verdes area since 1970, and currently serves customers in the cities of Palos Verdes Estates, Rolling Hills, Rolling Hills Estates, Rancho Palos Verdes, and a portion of Lomita. To meet our customers’ needs, we purchase surface water from Metropolitan Water District of Southern California (MWD), which is imported from the Colorado River and the State Water Project in northern California.
Hermosa-Redondo
Cal Water has provided high-quality water utility services in the Hermosa-Redondo area since 1927. The Hermosa-Redondo system serves customers in the cities of Hermosa Beach, Redondo Beach, and portions of Torrance. To meet our customers’ needs, we use a combination of local groundwater and surface water purchased from Metropolitan Water District of Southern California (MWD), which is imported from the Colorado River and the State Water Project in northern California.
The Hermosa-Redondo water system currently includes 212 miles of pipeline, 17 storage tanks, four MWD connections, and well-head treatment facilities at two active wells, which remove iron and manganese from groundwater.
