A historic tunnel excavation has been completed on the Second Narrows Water Supply Tunnel in Vancouver. The infrastructure project aims to make the region’s drinking water system more earthquake resilient and help meet growing demand for safe drinking water. “The tunnel underneath the Burrard Inlet was excavated with the first slurry tunnel boring machine to be used in Canada, and the work was being done up to 100 metres underground,” said Sav Dhaliwal, chair of Metro Vancouver’s board of directors, in a statement. “Completing this tunnel is an important milestone in this project and a remarkable testament to the innovation that is being used in Metro Vancouver to bring clean drinking water from the North Shore to the rest of the region.”
