In San Francisco, we have a combined system that collects both stormwater and sewage in the same set of pipes. When the system reaches capacity in heavy rains, we can experience street flooding (especially in low-lying areas that used to be creeks or bays) and property damage. No sewer system, including San Francisco's, can be designed to manage all stormwater in ALL storms.
Year-round, our preventative operations and maintenance crews work hard to prepare for the rainy season by inspecting, cleaning, repairing, and replacing aging sewer infrastructure. Throughout the rainy season, our Storm Watch team is dedicated to monitoring the weather closely. They specially monitor low-lying neighborhoods on a regular basis (even in the middle of the night and on weekends), and more frequently during storms. Crews are ready to respond by clearing away dirt and leaves off the top of the catch basins and vacuuming out debris using giant (vac-con) trucks.
What Should I Do if a Backup or Flooding Occurs?
