The Penitencia Water Treatment Plant is the smallest of the three water treatment plants in Valley Water’s system.
Service area
This plant typically serves an area from Milpitas in the north to Aborn Road in the south, supplying safe drinking water to 270,000 residential and commercial users.
Water source
The South Bay Aqueduct (SBA), owned by the California Department of Water Resources, provides most of the water to the Penitencia plant. Water from the Sacramento-San Joaquin Delta is pumped into the California Aqueduct and then into the South Bay Aqueduct in Tracy. The SBA pipeline runs through the Livermore Valley and terminates at the Penitencia plant.
