Planned Water Service Disruptions are no longer posted to respect the privacy of the impacted customers, all of whom receive direct notification of the disruption.
Why are any planned disruptions necessary?Currently the City is in the process of performing system and seismic upgrades, along with increasing the storage capacity for the City's water distribution system. This work may cause some customers to experience lower than normal water pressures during high demand times of the year, such as warmer months and high usage times of day. You may also experience some cloudy water due to valving modifications done to support the affected areas.
Primary reasons for water quality changes and planned disruptions:
San Francisco Public Utility Commission (SFPUC)'s Routine Maintenance on the Hetch Hetchy supply system. While most of the time we are getting our water supply straight from the Hetch Hetchy aqueduct, periodically that aqueduct must be closed for maintenance and our supply is mixed with water from other reservoirs in the system. In those cases, the water is still high quality and meets all standards, but may be cloudy (due to air bubbles) or have a slightly different smell or taste.
The City's Ongoing Aggressive Maintenance Program to test ("exercise") and replace old water valves. An average of 100 valves per month are exercised and as many as 12 per month are replaced. Everyone benefits from these improvements to the water distribution system, and we thank our customers for any inconvenience they must experience while their water is briefly turned off. Customers always receive advance notice of these shut-offs.
Current water service disruptions: None at this time.
