San Rafael Sanitation District (SRSD)
San Rafael Sanitation District manages wastewater collection and pumping to the CMSA treatment
facility for most of the City of San Rafael and some unincorporated areas of Marin County.
The Las Gallinas/Santa Venetia area sewage flows are treated by a separate district,
the Las Gallinas Valley Sanitation District ( LGVSD).
SRSD's two members on the CMSA Board are drawn from SRSD’s
three-member Board, which consists of the Mayor of San Rafael,
a City Council representative, and a County Supervisor.
Traditionally, the Mayor and Council member have been the
CMSA Board members and appoints one alternate representative.
