North Shore Conveyance

Project Description

The North Shore Conveyance Project is a major Metro Vancouver infrastructure project designed to transport wastewater from the new North Shore Wastewater Treatment Plant to the Lions Gate Outfall through a 2,134 mm-diameter steel gravity sewer main. SWC was responsible for TBM rescue, installation of the large-diameter welded steel pipeline, lining and coating of welded joints, and installation of a 900 mm HDPE forcemain. One of the project’s most significant challenges was the installation of the sewer main adjacent to an active railway corridor. To overcome this constraint, SWC proposed an innovative trench stabilization solution that enabled construction to proceed safely and efficiently while maintaining uninterrupted rail operations.
