A New, Stronger Tunnel to Bring Hetch Hetchy Water to the Bay Area

The San Francisco Public Utilities opened on Friday a new cement-encased, steel-lined tunnel that runs from Sunol Valley to Fremont. It will carry an average of 265 million gallons of water a day for customers of the Hetch Hetchy Water System Improvement Program, which consists of more than 80 projects to seismically retrofit and upgrade an 80-year-old water system serving 2.6 million people in the Bay Area.
