Project Update
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 house!
