To provide reliable water supply, wastewater management, and flood protection — essential services for a thriving community and a healthy environment.
Sonoma Water was created as a special district in 1949 by the California Legislature to provide flood protection and water supply services. Legislation enacted in 1995 added the treatment and disposal of wastewater to Sonoma Water’s responsibilities.
It has been the mission of Sonoma Water since 1949 to effectively manage the resources in our care for the benefit of people and the environment. With more than two hundred dedicated professionals who work for Sonoma Water in a variety of fields ranging from engineering to biology, we strive to look forward, beyond today’s issues, to anticipate ways to advance our mission.
The Sonoma County Board of Supervisors acts as Sonoma Water’s Board of Directors. Sonoma Water is a separate legal entity created by State law, having specific limited purposes and powers, and separate sources of funding. Sonoma Water is thus different from County departments, which are created by the Board of Supervisors for administrative purposes, but are not separate legal entities.
