Construction to increase the plant’s capacity to 160 MGD consisted of the following: Approximately 600 feet of 108” Raw Water, 2,000 feet 78” Filtered water, including 72”, 78-in diameter Raw Water pipeline and tunnel, 48” Filtered water and 36” Backwash throughout the plant.

The plant treats all water from the two local reservoirs: Calaveras and San Antonio. Both reservoirs help provide water for 2.6 million customers in four counties throughout the San Francisco Bay Area.
Due to the aging of the SFPUC water system and the lack of redundant water supply systems, timing for deliveries was very critical because the “Shut-down” windows were very tight, so coordination between The general Contractor and Jifco, Inc. were very important all piping was built, tested, inspected and deliveries were made on time and correctly constructed.
