General Information
The Pescadero community’s source of drinking water before 1993 was small domestic wells, water from surface impoundments, and locally derived groundwater from wells installed in the alluvial aquifer of Pescadero and Butano Creeks. In the 1970’s and 1980’s these sources were found to contain relatively high concentrations of nitrate and other naturally occurring salts. This prompted the development of a public groundwater source. County Service Area No. 11 (CSA 11) was established in 1988 to finance the development of this new water source and serve as the water provider for the Community.

The water system consists of two wells, one 135,000-gallon distribution tank and a distribution system. The water pumped from the wells meets all Federal and State water quality standards and does not require treatment. Water flows from the distribution tank through the distribution system mains by gravity. No distribution pumps are required. CSA 11 has approximately 90 residential and commercial customers.
