MMWD has two significant pipeline projects in the Ross area this year. The first one, now completed, is in the Town of Ross and the second one, now in progress, is in the Phoenix Lake area just outside the town limits.
This spring we replaced 2,700 feet, or approximately one-half mile, of pipe on Sir Francis Drake Boulevard in Ross between Winship Avenue and Lagunitas Road. The impetus for the project was the award of federal stimulus funds through the American Recovery and Reinvestment Act to the Town of Ross for the asphalt paving of Sir Francis Drake Boulevard across the entire town limits, Kentfield to San Anselmo, which the town plans to do this summer.
The new 12-inch welded steel pipe that replaces the original 1910 4-inch pipe will provide the added benefit of improving the overall reliability of the water distribution system because of the larger capacity pipe. The project began in late April and was completed in early June, almost two weeks ahead of schedule, by contractor Maggiora & Ghilotti, Inc., of San Rafael. The project cost was $459,864.
Beginning mid-June, contractor W.R. Forde Associates of Richmond began installing 3,600 feet, or more than two-thirds of a mile, of pipe in the Phoenix Lake area. That new pipeline is part of a critical water transmission line that delivers treated water from west Marin to central and southern Marin, serving approximately half of the district’s customers. This project is part of the district’s plan to increase the amount of water available for firefighting and to increase the reliability of the water system after an earthquake.
To facilitate the work and for public safety, some popular roads and trails in the area will be closed for the duration of the project, which is expected to take five months. Both MMWD and the contractor will make every effort to minimize the disruption to visitors and to open each route as soon as possible.
