reduced. This needed to be remedied by placing strips of material across the joints and fastening them with iron bands. A further challenge occurred in the winter of 1915–16. Parts of the newly constructed pipe got taken out by landslides, and repair was difficult, since the construction railway no longer existed. When the city began to outgrow demand, the pipe section from Sooke to the
Humpback Reservoir was decommissioned, in 1970. The pipe had begun to show its age, with many leaks and damage from falling trees and rocks. It was then replaced with the 8.8 km (5.5 mi)

The factory was very efficient and used steam to accelerate the curing of the concrete segments. In one eight-hour shift, 150–160 segments were produced. The segments were winched up the hill 450 feet (137 m) above the construction site. Three small locomotives were used to bring segments to both ends via a temporary
315:) gauge railway, and the pipe was constructed from the ends to the midpoint. At the ends, tripod derricks would unload the segments and place them on the crushed railbed while the tracks were removed. All trees on the 100 ft (30.5 m) right-of-way were cleared so that they could not fall and crush the pipe.

The flowline was never highly efficient. When the taps were opened in 1915, the water that came through was of high quality, but it was soon discovered that it experienced 50–75% water loss throughout its length, depending on the season and temperature. During summer however, the leaking was slightly

Every 600 metres (660 yards) or so, there are access hatches meant for periodic maintenance from the inside by workers. 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

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. The city hired the Pacific Lock Joint Pipe Company to cast the pipe segments, and using their patented design, constructed the pipeline. In between 1911

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. The engineering firm Sanderson and Porter specified 40-inch pipe, but the company already had 42-inch molds made up, so they decided to use them instead.

The portion of the old pipe from Sooke Lake to Sooke remained in service after the
Humpback Reservoir section was decommissioned. 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.

and bound with iron bands. These were built to reduce the length around the longest of ravines. 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

During the flowline's operation, caretakers lived along the route in small cabins. They rode recumbent tricycles on the pipe with tilted rear wheels to stay on top. During their routes, they were on the lookout for cracks in the pipe, leaky joints, and trespassers.
551:
There are 54 trestles along the 44 km (27 mi) length of various sizes, spanning ravines. During construction, temporary timber trestles were built alongside the proposed trestles to avoid delays and speed up the building of permanent concrete trestles.
269:. Leigh Hodgetts, CRD Waterworks superintendent, reported that the westernmost section of the flowline is still used to carry Sooke's water supply, via a 16-inch interconnecting pipe feeding the Sooke distribution system from Charters Creek to Sooke River Road.
