OUR COMBINED SEWER SYSTEM
Square Miles in SF
MGD = Million Gallons per Day
Miles of Pipes
Treated Per Year
We are making much needed sewer repairs all across San Francisco. More than 30% of our sewers are 100 years or older; some date back to the Gold Rush!
What does Sewer Repair Work entail?
Sewer Repair Work involves replacement or repair of defective or broken sections of the main sewer and sewer laterals (sections that stretch from the face of the curb to the main sewer pipeline.) These sewer repairs are crucial in providing uninterrupted sewer service and protecting public health and environment.
During the repair work, crews will use heavy equipment such as excavators, front-end loaders and concrete mixers.
How long does it take?
Sewer Repair Work typically takes anywhere from two days to two weeks. To reduce impacts on the community, we might repair several sewer lines on one block at a time.
Parking and Traffic: During work hours, parking will be unavailable on the block where repairs are taking place. We might have to close some traffic lanes, though we will provide local access for residents and businesses. No parking signs will be posted 72 hours in advance of the work.
Emergency Sewer Repair/Replacement Work
We plan most of our sewer construction projects, and have in place a robust maintenance program to prevent emergencies. With some of the sewer pipes that are 150+ years old, the system can fail without warning. These can be anything from sewage backing up onto the street or inside properties, broken main or side sewer pipes, sinkholes, etc. These emergency situations require our crews to immediately respond and remedy the situation to make sure public health and the environment are kept safe. They are sometimes referred to as “emergency dig-ups.” Neighbors may experience night/weekend work, removal of street parking, and partial traffic lane closure. For information on emergency work, you can call 311 or send us an email at firstname.lastname@example.org.
While these sewer repairs address the immediate needs of our sewer system, we are also embarking on the Sewer System Improvement Program (SSIP). SSIP is a 20-year, multi-billion dollar citywide investment required to upgrade our aging sewer infrastructure. The SSIP is the result of a n eight-year community planning process and will ensure a reliable, sustainable and seismically safe sewer system now and for generations to come.
Customer feedback is important to us as we work to upgrade our infrastructure. If you have questions or concerns, or want to share your experience with us, please fill out our brief sewer system customer service survey
