Serving Fremont Valley, Grand Oaks, Lancaster, Lake Hughes, and Leona Valley
Cal Water’s Antelope Valley District was formed in 2000 with the purchase of Antelope Valley Water Company, which began serving the area in 1965. On July 1, 2007, Cal Water took over ownership of the Grand Oaks system. Previously, we served customers and maintained the Grand Oaks system through an operating contract.
We serve approximately 1,400 customer connections in our Fremont Valley, Grand Oaks, Lancaster, Lake Hughes, and Leona Valley water systems. Most of the water we provide is pumped from local aquifers by wells located throughout our service area. We also purchase water from the Antelope Valley-East Kern Water Agency, which is imported from the State Water Project in northern California.
We proactively maintain and upgrade our facilities to ensure a reliable, high-quality supply.

How do I turn off the water supply to my house in the event of a break in my plumbing or a repair?
