Please Join Us for Coffee at the New Irvington Tunnel Project Open House
Thursday July 26, 2012
4:00 PM to 6:00 PM
151 Washington Blvd
Please stop by and check in
on the progress of the new tunnel. Our project team is available to answer your
questions and listen to your comments.
Over 10,000 feet (out of 18,660) has been tunneled to date. In June, miners excavating the
new tunnel from the Irvington Portal in Fremont met miners tunneling west from
the Vargas Shaft. This hole-through marked the completion of the
Irvington-Vargas tunnel segment.
In early August, workers will install
a 102-inch diameter steel pipe at the Irvington Portal that will eventually
carry drinking water from the Hetch Hetchy system to 2.6 million Bay Area
customers. The pipe, manufactured in California, is installed in 50-foot
sections and welded together inside of the tunnel. Pipeline installation is
expected to take three months.
We look forward to seeing you at the open
