Looking for a plumber in Marin County? Two water districts serve most of the county, one relying mostly on local reservoirs and one mostly on Russian River water, and many homes sit on steep, older lots. Call Same Day Plumber any time to reach a California-licensed plumber, or pick your city below.
Water, Sewer and Permits in Marin County
Marin Water serves central and southern Marin, including San Rafael. About 75 percent of its water is rain stored in 7 reservoirs, 5 of them on Mount Tamalpais; the rest is bought from Sonoma Water.
North Marin Water District serves Novato. It buys about 80 percent of its water from Sonoma Water and draws the rest from Stafford Lake.
Marin County Communities With Local Plumbing Guides
Rain-Fed Water and Dry Years
Because Marin Water depends so much on local rain, a dry winter brings watering limits faster here than in most of the Bay Area. Reservoir water is soft, about 4 grains per gallon in the district's 2020 report, and Russian River water is harder, so the blend changes with reservoir levels. Fixing leaks matters more here than almost anywhere in the state.
Hillside and Bayfront Plumbing
- Hillside homes have long, steep sewer laterals of old clay pipe.
- High street pressure on hills wears out regulators and supply hoses.
- Bayfront homes on soft soil see settling that pulls drain joints apart.
- Strap the water heater and know your gas shutoff.
