Manhole Rehabilitation

North Area Interceptor Phase 9

North Area Interceptor Phase 9

Scope

Michels Trenchless, Inc., one of North America's largest pipe rehabilitation contractors,  performed a cured-in-place (CIPP) lining project for the Metropolitan Council in Minnesota. The project included the rehabilitation of 3,850 LF of 96" pipe, 144 LF of 72" pipe, and reconstruction of manholes. The liners were cured-in-place with hot water. Michels Trenchless also installed a bypass system that pumped an average of 50,000 GPM.

Due to the weight of the single pipe installations, they could not be transported. Instead, Michels Trenchless assembled the liners at the project site. A climate-controlled structure was placed over the equipment and the pipes were wet-out and installed simultaneously.

The project was located alongside a busy regional highway with high traffic and limited access to small working areas. Crews also worked around several other utilities, including a 24" major gas main. Special safety precautions were in place so crews could safely complete the project.
