Primary Details
This project includes the rehabilitation of approximately 55,828 linear feet of 8-inch diameter, 1,151 linear feet of 12-inch diameter and 3,849 linear feet of 24-inch diameter gravity sewers with a cured-in-place pipe liner and rehabilitation of 237 manholes.
The collection system rehabilitation project will restore aging sewer pipes and manholes to restore their service life. Project impacts will be minimal compared to a collection system “open cut” replacement project since the rehabilitation methods are trenchless. The collection system rehabilitation will reduce pipeline failures and blockages that cause wastewater overflows that impact public health, safety and the environment. Additional project benefits include reduction in leaks that allow ground water and stormwater runoff to enter the collection system and cause wastewater overflows, reduction in energy needed to treat and convey the additional wastewater flow caused by leaking pipelines/manholes and reduction in pipeline failures that cause roadway depressions and cave ins.
