San Francisco Public Utilities Commission (PUC) General Manager Ed Harrington, joined by state and federal officials, dedicated the new state-of-the-art Tesla Treatment Facility in Tracy, Calif., on July 19, 2011.
With a capacity of 315 million gal per day (mgd), the new facility is the largest in the state and the third largest in North America. This facility is being commissioned nine months before the U.S. Environmental Protection Agency (EPA) establishes a new requirement for a second disinfectant for all unfiltered drinking water systems in the nation.
The ceremony and site tour will highlight the state-of-the-art facility—targeting LEED Silver certification—along with the UV equipment that will enhance the disinfection of drinking water for the 2.5 million Bay Area customers who receive water from the Hetch Hetchy regional water system.
The project is the only design-build construction project within the $4.6 billion Water System Improvement Program (WSIP) and was undertaken by PCL Civil Constructors Inc. and Stantec Inc., an architecture and engineering firm. It is one of 86 projects to repair, replace and retrofit aging pipelines, tunnels, reservoirs and other water delivery facilities within the Hetch Hetchy regional water system.
