About The Project

Metro Vancouver is constructing a new water supply tunnel deep under the Fraser River. The Annacis Water Supply Tunnel between the City of New Westminster and the City of Surrey is one of the five new marine crossings in the region built to withstand a major earthquake. When complete, it will help ensure the continued delivery of clean, safe drinking water to the communities south of the Fraser River well into the future. Construction is underway and is expected to be completed in 2028. The project involves building an entry shaft in Surrey and an exit shaft in New Westminster and using a tunnel boring machine to excavate the 2.3-kilometre-long tunnel. Once completed, a 2.6 metre diameter steel water main will be installed inside the shaft and tunnel, which will be connected to the regional water distribution system. Following construction, both shaft sites will be restored with green space.
