SAN FRANSISCO (Oct. 13, 2014) – Elected officials and senior water officials from San Francisco, San Mateo County, the San Francisco Public Utilities Commission (SFPUC) and Bay Area Water Supply and Conservation Agency (BAWSCA) celebrated the first Hetch Hetchy drinking water deliveries through the new Bay Tunnel on Oct. 15. The ceremony was held at the same place where the first Hetch Hetchy Water entered Crystal Springs Reservoir at the historic Pulgas Water Temple, 80 years ago this month. The first tunnel under San Francisco Bay and one of the SFPUC’s last major Water System Improvement Projects, the new Bay Tunnel is a seismically reliable water lifeline connecting Hetch Hetchy and East Bay water supplies to customers on the peninsula and in San Francisco. The SFPUC provides reliable, high-quality drinking water to 2.6 million residents in San Francisco, San Mateo, Santa Clara and Alameda counties.
