The District provides potable water services, fire flows, parks, and streetlighting services to thousands of residents of North Monterey County. The District provides these services from the Pajaro River in the north, to Moss Landing in the west, to the Highway 101 corridor in the south. Part of PSMCSD’s senior groundwater rights were granted by the U.S. District Court in San Jose, CA. It is the only public agency which provides public potable water services in the Pajaro, Elkhorn, and Prunedale areas.

The PSMCSD water system is regulated by the State Water Resources Control Board and Monterey County Environmental Health Department.
