The Southside Flats Sewer Separation Project looks to create dedicated storm and sanitary sewers on several South Side Flats streets to ensure more reliable sewer service for our customers. This portion of the sewer system is currently “combined,” which means the pipes carry both stormwater and sewage, which can lead to overtaxed pipes during heavy stormwater events. Too much sewer flow during heavy rains can cause basement backups, overland flooding, and pollutated waterways in our region. 

Limited work has begun on S. 18th, with more sewer separation and water main replacement work to come on S. 19th Street and Wharton Street. Join the PWSA project team to learn more about the project and ask any questions you may have.
