About the project
The North Interceptor, East Arm (NI-EA) which conveys sanitary and combined sewer flows from the Oakland and Macomb County communities, had suffered from significant deterioration, including loss of concrete liner thickness, exposed reinforcing steel, scaling, and cracks. In 2020, the pilot project for the rehabilitation of 407 meters of the PCI-4 Interceptor was initiated.
Channeline’s multi segmental liner was selected as the solution. This product’s unique tapered tongue and groove joining system allows pipe liners to be broken down into multiple components, facilitating shipping for large-scale projects like this, and reducing overall shipping costs by reducing the number of containers needed. Additionally, the Channeline system enabled trenchless installation in areas with difficult access such as manholes and maintenance chambers.
