Serving Chico and Hamilton City

Cal Water's Chico District was formed in 1926 with the purchase of the Chico Water Supply Company, Chico-Vecino Water Company, and the C.C. White Water Company. We began serving Hamilton City in 1962. Our company-wide water quality assurance program includes vigilant monitoring throughout our systems and testing at our state-of-the-art laboratory.


To meet the needs of our Chico customers, we utilize 68 wells to pump an average of 27 million gallons of groundwater per day, which is delivered through 373 miles of pipeline, eight storage tanks, and nine booster pumps.

Hamilton City

Cal Water has provided high-quality water utility services in the Hamilton City area since 1962. To meet the needs of our Hamilton City customers, we utilize three wells to pump an average of 0.56 million gallons of groundwater per day, which is delivered through 7.7 miles of pipeline.
