South Bay Pumping Plant
Known as the heart of the South Bay Aqueduct, the South Bay Pumping Plant is located at the upper end of Bethany Reservoir and lifts water into the first reach of the South Bay Aqueduct. It is situated in the northeastern corner of Alameda County, about 12 miles west of Tracy. The plantâs staged construction took place between 1960 and 1969. A 2008-2014 enlargement project added four pumping units, a new pipeline, and reservoir.
