SW Flower and Kelly Sewer Repair Project

Project Overview

Environmental Services is designing a project to replace almost 300 feet of 108-year-old public sewer pipe in the South Portland neighborhood on SW Flower Street between SW Corbett and Kelly streets. This sewer improvement will reduce the possibility of costly breaks, sink holes and sewage releases to homes, businesses and streets.

Environmental Services will be using a repair technique known as Cured In Place Pipe Lining (CIPP). During CIPP repairs, work crews access the sewer from manholes to insert a flexible liner inside the old pipe. Hot water or steam inflates and cures the liner, which gradually hardens to form a rigid, smooth surface that seals cracks and restores the pipe to near-new condition. The CIPP method is much less disruptive than the more traditional open trench method of sewer construction
