Construction is moving forward for the Sunol Valley Water Treatment Plant Expansion and Treated Water Reservoir Project. As of April 2011, construction for the overall project is 25 percent complete. Recently the contractor, Shimmick Construction Company, Inc., completed the extensive earthwork and soil nail wall required to build the new treated water reservoir, which included the removal of over 400,000 cubic yards of material. This work is part of various improvements that will enable the treatment plant to treat enough water to meet basic customer demands alone for up to 60 days after a major earthquake as well as improve water quality at the plant. All these improvements are expected to be completed in summer 2013.
