Marin Municipal Water District to Replace 106-year-old Pipe in Sausalito

Marin Municipal Water District (MMWD) will replace over a half mile of dated, leak-prone cast iron pipeline in the City of Sausalito ahead of the city’s repaving project scheduled for the summer of 2016. The Sausalito Pipeline Replacement Project will begin late November 2015 and is estimated to be completed in February 2016.

This project will use 8, 6 and 4-inch welded steel pipe due to its improved reliability in the event of an earthquake and increased fire flow capacity. The original pipeline, installed in 1909, has been the source of numerous leaks, making it a good candidate for replacement.

The lowest responsible bid for the project was submitted by Maggiora & Ghilotti, Inc. in the amount of $744,996. Streets impacted by this project include: Girard Avenue, Santa Rosa Avenue, Crescent Avenue, West Street, Valley Street, and Third Street. 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 Sausalito 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, except in years of peak capital improvements, when the CIP expenditures have reached 40% of the total district 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.
