About the project
When the City of Victoria, British Columbia, set out to rehabilitate sections of its 150-year-old brick sewer system, it faced a dual challenge: addressing structural deterioration while preserving the integrity of its heritage neighborhoods. PW Trenchless Construction was brought on for their trenchless expertise and commitment to non-invasive infrastructure solutions. Channeline was selected as the ideal lining system due to its high strength, lightweight structure, and ability to be custom-manufactured for a precise fit—making it particularly well-suited for the city’s irregular, historic sewer profiles.
The project involved relining over 258 linear meters of aging sewer in three distinct profiles, including two arches and an ovoid in varied diameters. Each profile was engineered by Channeline to match the host pipe’s unique dimensions and structural requirements, allowing for smooth hydraulic transitions and consistent performance across the network.
Despite tight timelines and urban constraints, Channeline’s ease of installation enabled PW Trenchless to deliver the project on schedule, under budget, and without resident disruption. The result was a seamless integration of modern engineering into Victoria’s historic infrastructure; extending the life of the brick sewers while preserving the character and calm of the neighborhoods above.
