This project will require excavating 3 access pits over the interceptor pipeline. The project will also include rehabilitating four maintenance-holes in this segment of the interceptor. This rehabilitation project will address critical pipeline corrosion and reduce the risk of pipe failure.

Slip Lining: Less time, less construction, fewer traffic impacts.
Slip lining is a trenchless method used to rehabilitate existing pipelines with minimal excavation. In this process, a slightly smaller, prefabricated pipe is inserted into the damaged host pipe and then grouted into place. This technique restores the structural integrity of the pipeline, prevents leaks, and extends its service life. Slip lining significantly reduces construction time, costs, and surface disruption, making it a less invasive alternative to traditional pipe replacement methods.
