Serving You Since 1929
The Mid-Peninsula Water District (MPWD), formerly Belmont County Water District, was formed in 1929 from the physical plant of seven independent systems, including the Spring Valley Water Company, which were united and began functioning as a public utility in 1930.
The mission of MPWD is to deliver a safe, high-quality, reliable supply of water for current and future generations in a cost-effective, environmentally-sensitive, and efficient manner. Learn more about MPWD HERE.
Our major water source originates from spring snowmelt flowing down the Tuolumne River to storage in Hetch Hetchy Reservoir. The pristine, well protected Sierra water source is exempt from filtration requirements by the United States Environmental Protection Agency (USEPA) and State Water Resources Control Board’s Division of Drinking Water (SWRCB). Water treatment provided by the SFRWS, including disinfection by ultraviolet light and chlorine, corrosion control by adjustment of the water pH value, fluoridation for dental health protection, and chloramination for maintaining disinfectant residual and minimizing disinfection byproduct formation, is in place to meet the drinking water regulatory requirements.
The Hetch Hetchy water is supplemented with surface water from two local watersheds. Rainfall and runoff from the 35,000-acre Alameda Watershed in Alameda and Santa Clara counties are collected in the Calaveras and San Antonio reservoirs, and delivered to the Sunol Valley Water Treatment Plant (SVWTP). Rainfall and runoff from the 23,000-acre Peninsula Watershed in San Mateo County are stored in the Crystal Springs, San Andreas, and Pilarcitos reservoirs, and delivered to the Harry Tracy Water Treatment Plant.
In coordination with the City of Belmont's permitting process, the Mid-Peninsula Water District (MPWD) reviews customer landscape plans regarding commercial and residential new development / construction, remodels, or additions on all lot sizes in excess of 1,000 sq. ft. in compliance with its Water Efficient Landscape Ordinance (WELO).

Catalog of Enterprise Systems
CA Senate Bill 272 Compliance
Approved on October 11, 2015, SB 272 added a section to the California Public Records Act requiring local agencies to create a catalog of Enterprise System with annual updates.
The Public Records Act was enacted in 1968 and is a component of California’s commitment to open government. MPWD shares that commitment. Section 6253 of the Government Code provides that every person has a right to inspect any public record except those specifically exempted by law.
