The Marin Municipal Water District will be installing three barges in Alpine Lake as part of a project designed to yield more water from the reservoir system in times of drought. In order to accomplish this work, the Fairfax-Bolinas Road will be closed in each direction between Azalea Hill and Ridgecrest Boulevard from January 24 – 28, 7:00 a.m. – 4:00 p.m. The closure applies to all motorized vehicle, bicycle and pedestrian traffic. We apologize in advance for any inconvenience.
The barges will support two 200-hp vertical turbine pumps and a valve manifold for the pumps. The pumps will replace an aging 400-hp submersible pump that transfers water from Alpine Lake to Bon Tempe Lake from where it can be sent to the Bon Tempe Treatment Plant. The new barge-mounted pumps will be installed in a deeper part of the lake, allowing the district to draw from water that is currently inaccessible.
