This webinar will review the planning, design and construction of the San Francisco Public Utilities Commission’s (SFPUC) recently completed Tesla Treatment Facility – now California’s largest ultraviolet (UV) disinfection water treatment plant. The unfiltered Hetch Hetchy water supply treated at this facility constitutes about 85 percent of the water supplied to retail customers in the City of San Francisco and wholesale suburban customers in surrounding Bay Area counties. The agency built the new Tesla Treatment Facility to comply with new U.S. EPA Long Term 2 Enhanced Surface Water Treatment Rule that requires unfiltered supplies to attain a minimum of two-log Cryptosporidium inactivation and the use at least two different disinfectants. For this facility, the agency chose ultraviolet light and sodium hypochlorite as the disinfectants.
Participants in this webinar will learn about the challenges faced in the planning and design process to develop satisfactory design criteria, as well as gain an understanding of the EPA’s treatment requirements for an unfiltered water supply. Additionally, as an unfiltered supply, the planning process had to account for the possibility of sand/grit and aquatic or terrestrial vegetation in the aqueduct. Minimization of headlosses, adjustment for high-pH influent, and ensuring good mixing of chemical additions were other design challenges. The Design/Build project team will also review construction challenges and successes, such as adhering to tight shutdown windows for the Hetch Hetchy Aqueduct and timely procurement of materials to meet the aggressive construction schedule.
