What is sliplining
Sliplining is a trenchless method of repairing or upgrading an existing pipe without digging a trench. Instead, crews excavate access pits where a new slightly smaller pipe is inserted and pulled through the old pipe using the existing pipe as a pathway.
This method of construction reduces the need for extensive excavation, minimizing impacts to the area.
In late June 2024, a sewer main leak occurred on Terminal Avenue between Quebec and Main streets.
City crews responded immediately to stabilize the area and complete temporary repairs, including installing an above-ground bypass pipe between Station Street and Quebec Street.
What's happeningPermanent repairs begin fall 2026
In fall 2026, we'll begin preparing the area for sewer construction. Construction will start later in the year.
To reduce disruptions in this busy area, much of the work will be completed using trenchless construction methods, which require less excavation than traditional methods.
Some road and sidewalk closures will be in place during construction. Follow posted signs and allow extra time when travelling through the area.
