The City of Lake Norden was experiencing high inflow and infiltration (I/I) in its sanitary sewer system due to cracks and leaking joints in old and deteriorating clay-tile sewer. During the Facility Planning process, the Cured-In-Place-Pipe (CIPP) method was recommended as a cost-effective method for sewer repairs. The CIPP method greatly reduces the amount digging and street restoration required. The CIPP process involves inserting a resin-saturated felt liner into existing sewer pipes, which is then pressed tightly against the existing pipe wall with heated water or steam forced through the pipe. The resin hardens, and the cured liner creates a new pipe free of cracks and holes within the existing sewer pipe. 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.
