The Delaware Trunk Sewer is constructed primarily of uncoated, reinforced concrete pipe, the interior of which has been corroded to the point that the pipe has reached the end of its useful life. The project will rehabilitate approximately 3,200 linear feet of the existing sewer line using a cured-in-place pipe (CIPP) rehabilitation method. This method involves inserting a thick plastic liner into damaged sewer pipes and curing the liner by circulating boiling water through it. Bypass piping would be implemented to allow continued wastewater service during project construction. In some locations, the existing sewer pipe has deteriorated to the pint that spot repair of the pipe using conventional cut-and-cover methods in the street is necessary.
