Service Alerts
Your service may be interrupted for a variety of reasons. We make every effort to notify customers before interrupting service if a service outage is related to planned maintenance or improvement activities. However, emergency repairs require service to be shut off without advance notice. SFPUC crews work tirelessly 24/7 to monitor the system and respond to water main breaks, power outages, and sewer issues regardless of weather, holiday, or time of day. If you are experiencing a water, power, or sewer emergency or service problem call our 24-hour hotline at 3-1-1 or (415) 701-2311 from outside SF or log on at sf311.org.
Service interruptions are posted on Nextdoor by neighborhood and may be listed below.

Water Main Breaks
SFPUC operates and maintains 1,200 miles of water pipelines also called water mains in San Francisco. Approximately 20% of San Francisco’s water pipes are about 100 years old. Although we have an active program to replace aging and vulnerable water mains each year, we are not able to prevent all water main breaks. On average, there are between 100 to 200 water main breaks in our system per year. Learn more about water main breaks.
During a water main break, customers near the break may experience temporary changes to their water such as discolored water. Open the cold water tap as close to your meter (the sidewalk) as possible, and let it run for 3 to 5 minutes. If it is still brown or milky, wait one hour and repeat. Learn more about dirty or discolored water.
Power Outages
Power outages can occur for a variety of reasons – whether unplanned or planned. We recognize the inconvenience that a loss of electricity can cause. We want to make sure you are prepared in the event of a service interruption and how you can stay safe.
