Belmont’s Water Supply: Utility Providers and What Homeowners Should Know
A public water district, not a private utility, drawing from the same source as San Francisco itself

MPWD Mid-Peninsula Water District |
1929 District Formed |
Hetch Hetchy Primary Water Source |
Public Agency Not a Private Utility |
Belmont’s water doesn’t come from a private company the way it might in a neighboring city. It comes from a public agency with nearly a century of history, and the source of that water is worth knowing about.
A Public District, Not a Private Utility
Belmont’s water is provided by the Mid-Peninsula Water District, formerly known as the Belmont County Water District, a public agency formed in 1929. This distinguishes Belmont from cities served by investor-owned utilities like California Water Service, since MPWD is governed as a public entity rather than operated for private shareholder profit.
The Same Premium Source as San Francisco
Hetch Hetchy Water
Belmont’s primary water source is Hetch Hetchy Reservoir, fed by Sierra Nevada snowmelt from the Tuolumne River, the exact same source that supplies San Francisco’s famously high-quality tap water. This is a genuinely notable fact for a suburban Peninsula city, and it means Belmont residents benefit from water quality widely regarded as among the best in California, without the filtration concerns some other regional sources carry.
Ongoing Infrastructure Investment
Like any water system, Belmont’s requires ongoing maintenance. The district has active infrastructure projects underway in 2026, including tank recoating work, part of routine capital investment to keep the delivery system in good condition rather than a response to any specific problem.
What Homeowners Should Actually Know
| Your water bill comes from Mid-Peninsula Water District directly, not a private company or the City of Belmont itself |
| As a public agency, MPWD’s rate-setting process and board meetings are subject to public records and open meeting requirements |
| Drought-year restrictions, when they occur, come through MPWD directly, and current landscaping protections under state law still apply |
| Redwood Shores, though sharing Belmont’s school district, is served by a different water provider given its separate Redwood City location |
Key Takeaway
Belmont’s water comes from a public district drawing from the same premium Hetch Hetchy source as San Francisco, a genuinely positive, under-the-radar fact about living in the city.
