Marin Municipal Water District (MMWD) will begin a project to replace nearly a mile of dated, leak-prone cast iron pipelines in the Town of Ross beginning mid-March with completion scheduled for June.
The original pipelines were installed in 1908, 1920, and 1947. Due to their age and leak history, the pipes have reached the end of their usefulness and are due for replacement. This project will replace the three existing pipelines with one 12-inch welded steel pipe, which offers improved reliability in the event of an earthquake.
The lowest responsible bid for the project was submitted by W. R. Forde Associates of Richmond in the amount of $868,933. The construction will be in Lagunitas Road between Glenwood Avenue and Sylvan Lane with piping connections to side streets intersecting Lagunitas Road in this stretch. Both the contractor and MMWD will make every effort to minimize traffic disruptions during construction.
This project aligns with MMWD’s five-year strategic plan to improve water supply resiliency and maintain facilities and equipment sufficiently. The Lagunitas Road Pipeline Replacement Project is funded by the district’s Capital Improvement Program (CIP). CIP projects are prioritized to support and enhance the district's efforts in promoting the best possible service capability to the district's customers.
The annual CIP expenditures are, on average, about 25% of the district's total annual expenditures. MMWD has 900-plus miles of pipe to maintain and replaces approximately 7 miles per year at an average cost of $225 per foot, or $1.2 million per mile.
Customers with questions about the project can contact Jeff Ohmart with MMWD’s Engineering Division at 415-945-1574.
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.
