Public Works is taking a proactive approach in rehabilitating sanitary sewer in the downtown area to avoid failures.  Cured in Place Pipe (CIPP) lining with manhole rehabilitation will be the focus of this project to reinforce structural integrity of the collection system.  Existing pipe segments are within constricted alleyways of the project boundary, which is Clark Street to the west, South Front Street to the north, Plum Street to the east, and First Street to the south.  Additional failing pieces in the area may be assessed to determine the best rehabilitation method.  Segments are mostly 8-inch pipe, with total length of approximately 13,000 linear feet.
