San Rafael Sanitation District - The San Rafael Sanitation District's mission is to protect the public health and the environment through proactively planning and operating a fiscally responsible and safe wastewater collection system. We serve the Central San Rafael area, south from the top of Puerto Suello Hill and includes the unincorporated areas within this jurisdiction. Our crew of eight maintains 32 pump stations, 13 miles of force main, and clean 132 miles of sewer pipelines. This collection and transportation system then delivers wastewater, for treatment to the Central Marin Sanitation Agency.
