Menlo Park Municipal Water

Menlo Park Municipal Water provides water to approximately 16,000 residents through 4,000 service connections within two service areas: the Upper Zone (providing water to the Sharon Heights area) and the Lower Zone (providing water to areas east of El Camino Real). All of the water provided is purchased from the San Francisco Public Utilities Commission and is piped from the Hetch Hetchy reservoir in Yosemite National Park to Menlo Park through the San Francisco Regional Water System. On average, 85 percent of the regional water system's water comes from the Tuolumne River watershed and 15 percent comes from local watersheds in the East Bay and Peninsula

Cross-connection control program


The San Mateo County Environmental Health manages the Menlo Park Municipal Department ’s cross-connection control program. They will send and receive test notifications, maintain a database, certify approved backflow testers, and perform backflow surveys to determine if backflow prevention is needed. They require that any backflow tester you hire must be listed on the County’s list of Certified Backflow Prevention Testers, and that the tester must tag assembles with a County tag. For information about Environmental Health’s cross connection program, please contact Kate Elgin from the County at 650-399-6919.
