San Leandro in Alameda County, California — The American West (Pacific Coastal)
Giant Water Filters
Lake Chabot Historical Walk
Lake Chabot Dam was built in 1874. The Contra Costa Water Company initially tried to filter the water through a series of screens. The screens were unable, however, to capture impurities, suspended particles, and small insects from the delivery system. Public complaints about the sulfuric flavor of the water eventually led to the design and installation of the Hyatt filters 14 years after the dam was built. Although no longer functional today, these filters stand as testimony to an era when water delivery processes were more rudimentary.
Erected 2012 by East Bay Regional Park District.
