The City of Lake Norden was experiencing high inflow and infiltration in its sanitary sewer system due to cracks and leaking joints in old, deteriorated clay tile sewer. During the Facility Planning process, the Cured-In-Place-Pipe (CIPP) method was recommended for sewer repairs to save the City money. The CIPP method greatly reduces the amount digging and street restoration required. CIPP involves inserting a resin-saturated felt liner into existing sewer pipes. Heated water or steam is forced into the liner, pushing it tightly against the existing pipe wall and causing the resin to harden. The cured liner creates a new pipe within the existing sewer pipe that is free of cracks and holes. The project also included partial lining of sewer services and repairs to deteriorated manholes. Project funding was provided with a $515,000 Community Development Block Grant and an $812,000 State Revolving Fund loan.
