Document Description
The proposed New Irvington Tunnel Project (the Project) includes construction of a new Irvington Tunnel in the vicinity of the existing Irvington Tunnel. The new tunnel would be approximately 18,200 feet long and 10 feet in diameter, parallel to, and just south of, the existing tunnel. The project also includes construction of new portals at the east and west ends of the proposed new tunnel with connections for the existing and proposed Alameda Siphons on the east and for the existing and proposed Bay Division Pipelines on the west. The Project would meet the seismic reliability goal and the delivery and drought reliability goals of the SFPUC regional Water System Improvement Program (WSIP) by allowing the existing tunnel to be taken out of service for maintenance while continuing to meet the water supply needs of SFPUC customers through 2030.
