Sanitary Backflow Flooding

Sanitary backflow flooding can be caused by a blockage in the City's sewer system or the system's inability to handle excess water caused by a significant storm. When this happens, wastewater can flow backwards into homes.

Installing a sanitary backflow prevention device or sewage ejector pump can greatly reduce the risk of sanitary sewer flooding. Check out these fact sheets to learn about how they work and how to maintain them.
