New Irvington Tunnel Pipeline
San Francisco Public Utility Commissions    Southland Contracting    Tutor Perini Corporation
SFPUC Awards Contract for New Irvington Tunnel

Project Description:

     The New Irvington Tunnel will run 3.5 miles and have an internal diameter of approximately 8.5 to 10.5 feet. It will lay parallel to the existing tunnel between the Sunol Valley south of Highway I-680 and Fremont, California.

     The new tunnel will provide a seismically-designed connection between water supplies from the Sierra Nevada Mountains and the Alameda Watershed to Bay Area water distribution systems. Not only does it provide a seismically sound alternative to the existing tunnel, the new tunnel will allow the SFPUC to take the existing tunnel out of service for much needed maintenance and repair.
