San Francisco Regional Water System

The major water resource originates from spring snowmelt flowing down the Tuolumne River to storage space in Hetch Hetchy Reservoir. Our very well protected Sierra drinking water source is not affected by filtration requirements by the United States Environmental Protection Agency (USEPA) and State Drinking water Resources Control Table Division of Drinking Water (SWRCB-DDW). Water from Hetch Hetchy Reservoir gets the following treatment to fulfill all appropriate water standards for usage: ultraviolet light and chlorine disinfection, ph level adjustment for ideal corrosion control, fluoridation for dental health safety, and chloramination intended for maintaining disinfectant leftover and minimizing the organization of disinfection byproducts. Hetch Hetchy drinking water is supplemented with surface water coming from two local watersheds. Rainfall and runoff from the 35, 000-acre Alameda Watershed in Alameda and Santa Claus Clara counties are collected in the Calaveras and San Antonio reservoirs and are sent to the Sunol Area Water Treatment Herb (SVWTP). Rainfall and runoff from the twenty-three, 000-acre Peninsula Watershed in San Mateo County are kept in the Crystal Spring suspensions, San Andreas and Pilarcitos reservoirs, and they are delivered to the Harry Tracy Water Treatment Plant. In addition to local sources, the SWRCBDDW approved the use of Upcountry Non-Hetch Hetchy Sources (UNHHS), which consist of surface area water in Pond Eleanor, Lake Cherry wood and the associated creeks all conveyed with the Lower Cherry Aqueduct, Early Intake Tank and Tuolumne Water as additional water sources. The UNHHS water, if utilized, would be treated in the SVWTP before delivery to customers. All of us did not use the UNHHS in 2017. Drinking water at the two regional treatment plants is usually subject to filtration, disinfection, fluoridation, and ideal corrosion control simply by pH adjustment. Seeing that mid-2017, a small amount of groundwater from local water wells were added to the surface water materials. The use of local groundwater helps diversify the water sources besides making our drinking water source in San Francisco much more reliable..
