Cal Water’s Los Altos Suburban District
Serving Los Altos and portions of Cupertino, Los Altos Hills, Mountain View, and Sunnyvale
Cal Water’s Los Altos Suburban District was formed in 1931 with the purchase of the Los Altos Water Company. To meet the needs of our customers in Los Altos and parts of Los Altos Hills, Cupertino, Mountain View, and Sunnyvale, we use a combination of local groundwater and imported water. Our imported water, which is treated surface water purchased from the Santa Clara Valley Water District (SCVWD), comes from SCVWD reservoirs and the San Joaquin-Sacramento River Delta. Our water system includes 297 miles of pipeline, 65 booster pumps, and 46 storage tanks. We proactively maintain and upgrade our facilities to ensure a reliable, high-quality supply.
