Effective March 17, 2020 through April 7, 2020, in response to the San Mateo County Health Officer’s order imposing shelter-in-place restrictions, the MPWD activated its response plan, which provides limited staffing for essential services only. The MPWD’s offices and operations at 3 Dairy Lane in Belmont are CLOSED, but all staff are on standby for immediate response as necessary, and many are working remotely. During regular business hours (8:00 a.m. to 4:30 p.m) customers may contact the MPWD by email at or 650-591-8941. We will respond as quickly as possible and appreciate your patience and understanding.

If customers would like to make a payment they can drop it off at our two drop box locations: one outside the MPWD Office and one at the Carlmont Shopping Center.

The SFPUC has released a message regarding the water supply:

“During these stressful times, you do not need to worry about your tap water. San Francisco’s tap water is safe. Our rigorous water disinfection processes ensure that your tap water is safe from viruses, including COVID-19.

San Francisco’s tap water is plentiful and reliable. We plan for emergencies to ensure that enough staff members report for duty to keep the water flowing. In other words, COVID-19 has no impact on the quality and supply of San Francisco’s tap water. The same is true for our wastewater and power services."
