Active Alerts

January 21, 2022 - SFPUC Customers may temporarily experience discolored water or changes in water pressure in portions of the Excelsior, Mission, Castro, Downtown, SoMa, Western Addition, Hayes Valley, Fillmore, Lower Nob Hill, Cayuga Terrace and Portola Districts today, Friday, January 21, 2022 through Monday January 24th.

Crews are taking College Hill Reservoir out of service for a construction project and moving water between pressure zones. This might temporarily stir up sediment in the pipelines and cause discolored water or a change in water pressure. If your tap water looks discolored, let the COLD water tap closest to your meter run for 3 to 5 minutes. If the water does not run clear, turn the tap off. Try again in one hour. Learn more about discolored water. 

Your tap water continues to meet water quality standards and is safe to drink. Please call 311 with complaints or questions.
