The plant supplies most of South San Jose, including Almaden Valley, Blossom Valley and Santa Teresa. It also has ability to supplement the demands of Penitencia Water Treatment Plant when needed.

The objective of the STWTP Air Wash Pipeline Replacement Project (Project) is to extend the useful life and increase the reliability of the plant's water filtration system. The air wash system agitates debris on the filter media allowing the filters to be systematically cleaned in an efficient manner.

This includes replacement of approximately 900 LF of above-ground 12-inch stainless steel pipe, and relining of approximately 670 LF of underground 12-inch stainless steel pipe at the east and west filter basins and galleries. Staggering of this work will be necessary to maintain water production.
