[3] In 1912, the city of Victoria expropriated forty property owners on Sooke Lake and on the proposed flowline right-of-way (ROW), at significant cost.

[citation needed] At the factory located at Coopers Cove, the site of today's Stickleback Bar and Grill, round concrete segments, 36,000 in all, were mass-produced.

A man would lie prone on a cart and scrape moss off the inside of the pipe and clear sediments, rocks, and dead fish, which inevitably backed up in places.

Installed on top of these hatches were wire mesh domes, which reduced pressure buildup and helped aerate the water.

When the city began to outgrow demand, the pipe section from Sooke to the Humpback Reservoir was decommissioned, in 1970.

It was then replaced with the 8.8 km (5.5 mi) Kapoor Tunnel, bored through solid rock to the Japan Gulch Disinfection Plant, near Goldstream Provincial Park.

It was routinely patrolled to make sure marijuana grow ops weren't tapping into the pipe and to do periodic patching up as best as possible, but it still had many leaks.

[7] The water department of the Capital Regional District still owns pipe and the approximately 100 ft (30.5 m) wide corridor, which includes large trees, cliffs, and mossy bluffs.

The wooden trestles dip down one side of the ravine and go up the other, relying on the downward pressure to push the water back up.

These "dipping" trestles, known as "inverted siphons", were initially constructed of concrete as well, but the material is very weak in tension and resulted in cracked segments due to the pressure of 39.017 psi (269.01 kPa) (abs).

These segments can be found at the following locations: As part of a beautification project around the CRD, plain electrical boxes were outfitted with decorative images of the pipe trestles.
