Background and Analysis:
The Wastewater and Stormwater Utilities develop lists of priority pipes that need repair, based on the results of video inspections and condition ratings established by the Pipeline Assessment and Certification Program. Pipe sections are then identified for which trenchless technology (CIPP) will be the most effective repair.
This project will repair approximately 5,500 feet of sewer pipe and 550 feet of stormwater pipe.
Climate Analysis:
This project will rehabilitate nine segments of aging sewer pipe and three segments of aging stormwater pipe with a cured in place lining. By using cured in place lining, a complete replacement of sewer and stormwater pipe using open trench excavation, a much more energy intensive alternative, can be avoided. Proactively rehabilitating aging sewer pipe by correcting defects will prevent groundwater from entering the sewer collection system, thereby lowering the amount of water that is conveyed, pumped, and ultimately treated at the LOTT Budd Inlet Treatment Plant, resulting in less energy use. Further, by rehabilitating aging stormwater pipe, greater capacity for addressing rainfall events is created. For these reasons, the project supports strategy W1 (Increase the efficiency of water and wastewater infrastructure) and W3 (Reduce emissions from wa...
