San Mateo Tank Transmission Project

(Posted July 15, 2025) The North Marin Water District will be initiating the San Mateo Tank Transmission Project starting in August 2025 with an expected completion sometime in October 2025. This project involves installation of a new, large-diameter transmission main that will extend from the San Mateo Tank and connect to the existing distribution system along San Mateo Way. Project benefits include increased fire flows for the San Marin area and decreased pumping costs.
