Public Projects

The project is the discontinuation of gravity sewer system within the intertidal beach area by the District. Each of the four houses will have constructed a new Duplex Below Ground Private Pump System on their property which will pump up to Oak Drive and connect to a shared residential force main trench for all four force mains. The Contractor will obtain the building permit from the local building jurisdiction prior to system installation on private property. The shared residential force main trench is within the Marin County Right Of Way and requires and Encroachment Permit.”

Project primarily consists of replacing approximately 2,530 LF of sewer pipe with 6” and 8” HDPE pipe at 7 different locations by the pipe burst method and replacing lower lateral pipes at the same locations.

The Work consists of removing and replacing five plug valves on force mains that have become inoperable on three different sites in the City of San Rafael. On one site belonging to the San Rafael Sanitation District, a new vault will be constructed around the existing force main to house the new valve. On the other two sites, both along Point San Pedro Road, the valves will be replaced by direct bury. This work will be coordinated with the District’s operations and with the Central Marin Sanitation Agency’s Wastewater Treatment Facility to take advantage of a planned system shutdown.

The project consists of repairing and replacing approximately 12,000 LF of (6" to 21") pipe in various locations by open trench and pipe burst. Work also includes lateral and manhole replacement, paving and striping.
