Sunol Valley Water Treatment Plant Improvement Project

Sunol Valley Water Treatment Plant Improvement Project

The SFPUC proposes to add an additional 40 million gallon per day (gpd) of treatment capacity at the existing Sunol Valley Water Treatment Plant (SVWTP), construct a new treated water reservoir facility adjacent ot the SVWTP,and construct an additional treated water conveyance pipeline (herein after referred to as "the SVWTP Improvement Project" or "the project"). The proposed alignment for the new conveyance pipeline from the SVWTP generally runs northward from the SVWTP to the Alameda West Portal of the Irvington Tunnel, a distance of approximately 1.7 miles. The entire project is contained within the Alameda Creek watershed. The purpose of the project is to increase the total sustainable treatment capacity (the highest rate at which plant production can be expected to meet water quality requirements for a period of 60 days, given normal source water conditions) of the SVWTP from 120 mgd to 160 mgd, meet California Department of Health Services requirements for treated water reservoir storage, and provide an additional conveyance pipeline to add transmission capacity to the reservoir storage, and provide an additional conveyance pipeline to add transmission capacity to the SFPUC regional water system in the Sunol Valley and alleviate disruption of operations in the event of an earthquake.
