high-pressure water to chip, score, and section the concrete in a controlled way. Segments were flushed and removed progressively to manage risk and maintain flow. “There was zero room for error,” Scott recalls. “If we damaged the pipe beyond repair, you’re looking at a very expensive and time-delayed process with a sensitive site above. The guys took the time and care the situation demanded.” Over 21 days, the crew cleared the obstruction end to end. Minor etchings to the host pipe were unavoidable but acceptable within the design parameters for relining. “The outcome was exactly what the client needed. We got it ready to be relined, and no surface area was disturbed.” Another standout effort took place in Alberta around the Parklands area, where Uni-Jet partnered with a leading liner contractor to prepare a major sewer for rehabilitation. The challenge there was sheer volume – over the course of a month or two, Uni-Jet removed more than 2.5 million pounds of debris from the line. “The scale surprised even us,” Scott admits. “The environmental coordination was crucial – this was a sensitive site with geologists on hand monitoring nesting grounds and eagles in the trees. Our team, the client, and the regulators worked in concert to make sure every step met environmental standards.” APRIL 2026
