The Countywide Water Service Review is a comprehensive overview of water service within Santa Clara County and includes all of the public agencies providing water service in the County as well as several private purveyors. In addition, the San Francisco Public Utilities Commission (SFPUC) and the Bay Area Water Supply and Conservation Agency are included since the water imported through the SFPUC’s Hetch Hetchy Water System is an integral component of the water supply in Santa Clara County. The Pacheco Pass Water District is included as well; its service area lies only partially within Santa Clara County, but it is providing water for natural groundwater recharge that benefits both Santa Clara and San Benito Counties.
