As Needed Water Service Line Replacement Program

If a galvanized utility service line is detected, a letter will be mailed to property owners no less than 45-days prior to the replacement of your service line.  

The entire process of replacing the utility service line will take approximately 3-4 days. There will be a temporary disruption of water service, expected to last between 60 to 90 minutes, while the new utility service line is being installed. Customers will be notified prior to their water being turned off. 

Replacement of the service line sometimes stirs up small amounts of sediments in the water service. All water quality impacts will be short-term. However, to mitigate any change in water quality due to construction disturbances, SFPUC will provide instructions to flush faucet taps within your property immediately after construction and will also provide a filtering water pitcher and a 6-months’ supply of carbon filters for drinking and cooking at no cost. Using certified carbon filters removes any lead and other small debris stirred-up by the replacement work. Please use the water pitcher to filter your water when you receive it and change the filter per the manufacturer’s instructions. Water quality should return to normal within a month of construction.
