Stanley Park water supply tunnel

Metro Vancouver is planning to construct a major water infrastructure project, called the Stanley Park Water Supply Tunnel, approximately 30-50 m below ground level in Stanley Park. The new water supply tunnel will replace an existing water main that was built in the 1930s and is nearing the end of its service life.

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 for the region's growing population.

Construction is expected to start in fall/winter 2022 and complete by spring 2027.

Project work sites

Burrard Inlet

This is the site of existing Metro Vancouver water infrastructure located on Stanley Park Dr between Lumberman’s Arch and the Pipeline Road secondary route.

A new valve chamber will replace the existing infrastructure.

Central Shaft

This is the primary work site located in the north end of the parking lot at the Stanley Park Service Yard.

This will act as a base of operations for the project and the majority of excavated material will be trucked from this site.


The new valve chamber will be constructed adjacent to the existing Secondary Disinfection station.

The construction area is bounded by Nature House at north, tennis court at west, Chilco St at south, and an extension of Alberni St at east.

Mid-Park Connection

This is a minor work site at the intersection of Pipeline Rd and Tunnel Trail.

After new pipes are installed, the existing water pipe and the new water pipe will be tied-in at this location.
