The Sunol Valley Water Treatment Plant [SVWTP] Improvements Project has been a critical project in the SFPUC’s 10 year Capital Improvements Program [CIP] and one of the largest and most complex projects undertaken by the Utilities Engineering Bureau in recent years.
Phase I of the SVWTP Improvement Project increased the capacity and reliability of the existing plant. The improvements included construction of a new flow distribution vault, flash mix chamber, chemical feed building, and office and lab facilities. Seismic upgrade of existing structures was also performed. The project included siting and preliminary design of a new WTP and treated water storage reservoir [TWR]. A total of four alternative sites within the Sunol Valley were proposed for the location of a new WTP or reservoir, or both.
