Document Description
The proposed New Irvington Tunnel Project involves construction of a second tunnel parallel to, and just south of, the existing Irvington Tunnel. The new tunnel would be approximately 18,200 feet long with a finished, inside diameter of approximately 9-feet, and range from approximately 120 to 700 feet below the irregular surficial topography along its proposed alignment. The New Irvington Tunnel Project would also include construction of new portals at the east and west ends of the proposed new tunnel with connections to the Alameda Siphons on the east side, in the Sunol Valley, and the Bay Division Pipelines (BDPLs) on the west side, in the City of Fremont. The New Irvington Tunnel Project seeks to meet the seismic reliability and delivery goals of the SFPUC's proposed regional Water System Improvement Program (WSIP) by providing a new tunnel that would provide a seismically reliable transmission system between the Alameda Siphons and the BDPLs and allow the existing tunnel to be taken out of service for maintenance while continuing to meet the water-supply purchase requests of SFPUC customers.
