California’s first municipal water district, Marin Water was formed in 1912, and has grown to serve 191,000 customers in central and southern Marin County. With 75% of our water sourced locally – from the Mount Tamalpais Watershed and the hills of west Marin – our District’s fingerprint is unique. We maintain water supply infrastructure, including more than 900 miles of pipelines, but we also have important stewardship responsibilities for more than 22,000 acres of watershed lands. We invite members of the media to utilize any of the tools on this page to get to know our District, and share our story with your audiences.
