District Information

Serving Livermore and Crane Ridge Mutual Water Company

Cal Water's Livermore District was formed in 1927 with the purchase of the water system from Pacific Gas and Electric Company. In addition to the 17,900 customer connections in our Livermore system, we serve 25 customer connections under and operations and maintenance contract with Crane Ridge Mutual Water Company.

To meet our Livermore and Crane Ridge Mutual customers' needs, we use a combination of local groundwater pumped from 12 wells and surface water purchased from Alameda County, Zone 7 Water Agency.

Most of our water supply originates as snowmelt in the Sierra Nevada, which makes its way to the Bay Area using the San Joaquin-Sacramento River Delta as a conveyance system. Delta water is transported to Zone 7 via the South Bay Aqueduct (SBA). Zone 7 also uses local rain runoff stored in the Del Valle Reservoir and groundwater from the aquifer that lies below the Livermore-Amador Valley.

Water is delivered into Cal Water's distribution system through nine connections with Zone 7.

We proactively maintain and upgrade our facilities to ensure a reliable, high-quality supply.
