Central Marin Sanitation Agency is a joint powers agency or JPA formed by its member agencies,
which are special districts and municipalities in the San Rafael, Corte Madera and Ross Valley areas of central
Marin County, California. CMSA was formed for the purpose of constructing and operating a wastewater
treatment plant located in San Rafael.
The publicly owned and operated treatment plant treats an average of about 11 million gallons of wastewater a day.
We carry out a variety of tours and educational programs for students and adults.
We are both regulated and regulators. Our discharge quality to the San Francisco Bay is
monitored and regulated by the San Francisco Regional Water Quality Control Board (SFRWQCB)
and we in turn regulate commercial, industrial, and institutional discharges to the sewage
collection system. The terms of regulation of our discharge to the Bay are outlined by our
NPDES permit as measured by detailed laboratory results.
