Marin Municipal Water District (MMWD) will replace more than a half mile of dated and fire flow deficient cast iron pipeline in Forest Knolls, a community in unincorporated Marin County, in late September. Construction is scheduled to be completed in January.
The lowest responsible bid for the project was submitted by Team Ghilotti in the amount of $616,272. Streets impacted by this project include: Morelos Avenue, Juarez Avenue, Ramona Avenue and Rosario Road. Team Ghilotti and MMWD will make every effort to minimize traffic disruptions during construction.
This pipeline project will increase fire flow by replacing two and three-inch pipes installed in the 1910’s and 1920’s with new six-inch pipes. The material for the new pipeline was chosen based on the existing conditions at each project site. Welded steel pipe with tape exterior coating will be used on Juarez Avenue, Ramona Avenue and Rosario Road. Polyvinyl chloride (PVC) pipe will be used on Morelos Avenue.
This project aligns with MMWD’s five-year strategic plan to improve water supply resiliency and maintain facilities and equipment sufficiently and is funded by MMWD’s Fire Flow Improvement Program (FFIP). This program was developed cooperatively by local fire chiefs, county and city officials, concerned citizens and MMWD representatives. According to local fire chiefs, water availability for firefighting is one of Marin's primary public safety issues. Fire flow improvement projects will continue for the next 16 years.

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. The annual operating budget for the district for fiscal year 2015-16 is $66.8 million.
