Westborough Water District Office

The Westborough Water District (WWD), formerly known as the Callan Park County Water District was incorporated as a county water district in 1961. The authorizing statue that allowed the WWD to be formed falls under the California Water Code, section 30000.

The WWD is a Special District, which is a form of local government created by the Westborough community to meet a specific need. Special Districts have four basic characteristics:

  • A form of government
  • Governed by a board
  • Provides services and facilities
  • Has defined boundaries

Please visit Districts Make the Difference for additional information on Special Districts.

The WWD has approximately 4,000 residential, commercial and irrigation service connections. Since the first operation, the WWD has purchased 100 percent of its water supply from the City and County of San Francisco Water Department. The WWD service area covers approximately 1 square mile (West of 280 to Skyline Boulevard and South of King Drive in Daly City to San Bruno) and serves approximately 13,500 customers (see map below). The WWD has inter-ties connections with the North Coast County Water District (Pacifica) and the City of Daly City for emergency water service. The WWD is governed by an elected 5-member board. Board members are required to be residents of the WWD and registered voters. The WWD has more than 24 miles of water lines, uses an average daily consumption of one million gallons a day and has three steel water storage tanks. The WWD has a total of 6.3 million gallons of water storage. All of WWD's water comes from the Hetch Hetchy and local reservoirs. Also, the WWD owns the sanitary sewer system. Under an agreement, the sewer system is maintained by the North San Mateo County Sanitation District (City of Daly City). The WWD has an emergency stockpile of pipe, fittings and materials to perform repairs to the water system. In addition, the WWD is able to perform most emergency repairs using WWD staff without the delay of using outside contractors. The WWD office is located at 2263 Westborough Boulevard, South San Francisco, California 94080. Click here for directions to WWD Office.
