Our district operates and maintains approximately 200 miles of collection sewer lines and 19 pumping stations which collect, pump, and transport approximately four million gallons of wastewater per day to Central Marin Sanitation Agency. Our mission is to provide customers with high quality wastewater collection service through a system that has no avoidable sanitary sewer overflows at the lowest sustainable cost. Our public agency has a board of five elected officials, all of whom reside in our service area.

Ross Valley Sanitary District is committed to creating a positive workplace culture and actively works to foster an inclusive and engaging environment. Recently, we were featured in Municipal Sewer and Water Magazine for the success of our Core Competencies Training Program. The program has worked to catalog and document key Standard Operating Procedures which has in turn allowed the operations team to become more efficient and proactive in their work.
