Established in 1912, the Marin Municipal Water District provides high-quality drinking water to 190,300 customers in central and southern Marin County. Seventy-five percent of their water comes from more than 21,600 acres of protected watershed on Mt. Tamalpais and in the grassy hills of west Marin.
