San Mateo Tank Transmission Line

San Mateo Tank 24” Transmission Main for Fire Safety and Reliability

The project involves the installation of a 24-inch diameter main extending from the San Mateo Tank and connecting to the existing distribution system piping in San Mateo Way. When San Mateo Tank was originally constructed in the 1960’s, a temporary 12-inch main was also constructed to connect the tank to the distribution system. At that time, additional development was planned along the slopes of Mount Burdell, and the existing 24-inch main in Palmo Way was to be extended to the tank as development occurred. Subsequently in the 1970’s, the Mount Burdell Preserve was purchased by the Marin County Open Space District and no further development occurred. The existing 12-inch main connected to the tank represents a hydraulic bottleneck in the system.

All necessary permits have been obtained and staff is currently seeking grant funding through the FEMA Hazard Mitigation Program to fund the construction phase of the project.
