Document Description
All treated wastewater effluent from the SASM treatment plant in Mill Valley is conveyed through a 6 mile long pipe to Raccoon Straits of the shore of Point Tiburon. The pipe was installed in 1982 and included three cathodic protection (CP) systems along the route of the pipe. CP systems greatly reduce the possibility of pipeline failure caused by electrical corrosion. This project will refurbish the original three CP stations and will include two new stations to expand cathodic protection to the entire pipeline. This project will result in continued and improved protection of the existing pipeline. The capacity of the existing pipeline will not be changed by this project. Approximately 28,000 residents of Southern Marin County that are served by the SASM system will benefit from this project.
