The City of Cupertino water services are provided to residents and businesses through three separate water systems (City of Cupertino Water Service Areas). Two of those systems are owned and operated by investor-owned and operated private Class A utility companies. California Water Services (green area) provides water services within the northeastern portion of the City and San Jose Water Company (orange area) provides water service to the southeastern portion.

The City’s own water distribution infrastructure system (purple area) is located in the western portion of the City as shown in purple on the water services area map. The System purchases, treats and delivers approximately 3 million gallons of potable water per day to residences and businesses. The System is comprised of approximately 4,600 water service connections, 50 miles of pipelines, three storage tanks, one pump station and two wells. There is one emergency intertie each between the adjacent water systems operated by the City of Sunnyvale and the San Jose Water Company and the City-owned Water System.

The City’s System is currently operated by San Jose Water Company (SJWC) per a lease agreement that was executed in 1997 and amended in 2019. The lease was set to expire on September 30, 2022 but was extended by two additional years. This page provides information related to past, present and future operation of the City owned water system.
