Sonoma County Communities With Local Plumbing Guides
One River, Many City Systems
Because the cities share a source, a drought on the Russian River brings watering limits across the county at once. Day to day, the city on your bill handles meter leaks, pressure problems and main breaks. Windsor is the exception in one way: it also draws river water through its own facilities.

- Follow your water provider's notice before drinking or boiling.
