Project Overview
To meet the growing demand for drinking water in the region, Metro Vancouver is planning to construct a major water infrastructure project, called the Stanley Park Water Supply Tunnel, deep under Stanley Park. The new water supply tunnel will replace an existing water main that was built in the 1930s and is at the end of its service life.
Metro Vancouver is planning to tunnel deep underground to build a new water main and two valve chambers. The valve chambers will house underground pipe and valves to control the flow of water through the mains in the area. The new main and valve chambers will then be connected to the existing water distribution system.
To excavate the tunnel, install the water main and build the valve chambers, three shafts will be constructed in Stanley Park. The shaft locations, along with the tunnel alignment and construction process, were carefully selected based on rigorous geotechnical, environmental, archaeological, technological and traffic studies. At all three shaft sites, the construction areas will be restored to equal or better condition.
The project is in the detailed design stage and construction is expected to begin in late 2022 through 2027. When complete, the new tunnel will meet current seismic standards, help ensure the continued reliable delivery of clean, safe drinking water to the cities of Vancouver and Richmond, and increase the capacity of the existing system for the region’s growing population.
