Construction on the Port Mann Water Supply Tunnel is nearing completion. In late June the tunnel boring for the project was completed, and the tunnel boring machine extracted from the access shaft on the north side of the Fraser River. Now crews are installing the steel pipe which will line the one kilometer long tunnel. When completed, the water main will more than double the current water supply capacity of the existing main and service the growing Metro Vancouver communities south of the Fraser. Tim Langmaid, the project manager for Hatch Mott MacDonald took us underground, for an up-close look at the final stages of the work.
