Sewer Pipeline Rehabilitation Phase R - 1
Document Type
NOE - Notice of Exemption
Document Description
The project proposes to rehabilitate approximately 7.23 miles of existing sewer pipelines located within the City's right-of-way and within three City-owned easements using trenchless technology, installation of 23 new cleanouts, replacement of one cleanout, rehabilitiation of nine manholes, replacement of seven manholes, and 15 point repair locations. Two trenchless methods of sewer main rehabilitation may be used for this project. Both methods would require pulling the liner through the sewer main, curing it using hot water or steam, and cutting it at both manholes. The second method would use ribloc (spiral) liner, which would be pulled through the sewer main as plastic strips and then formed to the pipe to create a new pipeline liner within the existing pipe.
