MMWD to Begin San Geronimo Valley Pipeline Replacement Project

Marin Municipal Water District (MMWD) will replace a third of a mile of seismically vulnerable pipeline in the south side shoulder of Sir Francis Drake Boulevard in Woodacre. The project will begin in early November 2015 and is estimated to be completed in January 2016.

This project will use 36-inch welded steel piping due to its improved reliability in the event of an earthquake and increased fire flow capacity. The original pipeline, installed in 1957, is 33-inch concrete pipe which is more vulnerable to collapse and potential breaks which could result in treated potable water spilling into San Geronimo Creek.

The lowest responsible bid for the project was submitted by Maggiora & Ghilotti, Inc. in the amount of $649,600. Construction will be confined to the south shoulder of Sir Francis Drake Boulevard. Both the contractor and MMWD will make every effort to minimize traffic disruptions during construction.

This project aligns with the district’s five-year strategic plan to improve water supply resiliency and maintain facilities and equipment sufficiently. Customers with questions about the project can contact Jeff Ohmart with MMWD’s Engineering Division at 415-945-1574. Please reference the North Marin Line Project.
