MMWD to Construct New Pump Station to Better Connect Water Distribution System

Marin Municipal Water District (MMWD) will begin construction of a new pump station near the district’s Smith Saddle Tanks at the Smith Ridge Fire Road in the Town of Fairfax. This new pump station will increase water supply reliability by connecting the district’s distribution system to the San Geronimo Valley and mitigate the impacts of an emergency or planned shut-down of the San Geronimo Water Treatment Plant. Construction will begin in December and is expected to be completed in Spring 2017.


The new pump station will allow for the transfer of water from the North Marin Intertie to the Conifer Way Tank and consequently to the San Geronimo Valley. It will also support flows to the Fairfax Transmission Line. This project will include the installation of approximately 200 feet of 12’’ welded steel piping, vales, fittings, and site fencing. This work also includes installation of new electric service and remote communication facility.


The lowest responsible bid for the project was submitted by Thompson Builders Corp. in the amount of $717,000. Streets that may be impacted by this project include Glen Drive and Glen Fire Road.


Both the contractor and MMWD will make every effort to minimize traffic disruptions and noise during construction. The construction traffic will be limited to material and equipment delivery trucks, and traffic impacts are expected to be minimal as the project site is on MMWD-owned land with adequate on-site parking.


Customers with questions about the project can contact MMWD Construction Inspection Supervisor Dick Paulson (dpaulson@marinwater.org or 415-945-1569). This project aligns with the district’s 5-Year Strategic Plan Goal 1 (Water Supply Resiliency) and Strategy 4 (Ensure facilities and equipment are maintained and sufficient to support resiliency, water quality, watershed management and a productive workforce.)


MMWD is Marin County’s largest provider of drinking water, serving a population of 187,500 in a 147-square-mile area of south and central Marin County. The district owns and manages 21,635 acres of watershed land on Mt. Tamalpais and in west Marin. The primary source of water supply is rainfall captured in seven reservoirs, providing 75 percent of the water consumed each year. The remaining 25 percent is imported annually from the Russian River through an agreement with the Sonoma County Water Agency. MMWD also operates its own recycled water system. District operations are financed primarily by revenue from the sale of water.
