"Novel construction methods modernize sewers in an iconic riverfront neighborhood

 As part of our South Side Flats Sewer Rehabilitation project, taking place between South 18th Street and South 21st Street in the South Side Flats, Pittsburgh Water has chosen one such method to employ, known as trenchless sewer installation or sewer microtunneling.

Upon completion, this sewer rehabilitation project will ultimately separate the combined system and create dedicated storm and sanitary sewers on several streets in South Side Flats, meaning more reliable sewer service for our customers.

Combined sewers carry both stormwater and sewage, which can overtax pipes during heavy rain events. These storm events can cause basement backups, overland flooding, and polluted waterways in our region. "
