Who We Are

About the District

Chartered on April 25, 1912, the Marin Municipal Water District is the first municipal water district in California. Prior to that, water in central and southern Marin had been provided by several small, private companies, many of them subsidiaries to local real estate developers. Recognizing the critical importance of reliable water service, the community came together to create a publicly owned and managed water system. Our proud history is what drives our work, and it is at the heart of our mission. Today, we provide local water service to more than 191,000 people in central and southern Marin.
