Stanley Park Water Supply Tunnel - Chilco Shaft

The Greater Vancouver Water District   is planning to construct a major water infrastructure project, referred to as the Stanley Park Water Supply Tunnel, to replace a section of existing water supply infrastructure. When complete, the new tunnel will meet current seismic standards, help ensure the continued reliable delivery of clean, safe drinking water to the region, and increase the capacity of the existing system to support the region's growing population. The Project involves the excavation of a 1,400 metre long, 4.2 metre diameter, water supply tunnel that will range between 45 to 50 metres below the ground surface of Stanley Park, connected to three access shafts. The Chilco Shaft is located within the port authority's jurisdiction.
