WCW24

This project replaced a failing system to ensure the safe, daily conveyance of over 2.3 million litres of wastewater across the Red River in Winnipeg. The existing crossing was installed along the river bottom in 1978 and was connected to lands that became densely urbanized limiting replacement solutions. An alternate solution was developed to both reroute the force main and install it safely within the bedrock strata below the river. The solution required 780 metres of new force main including a 466-metre-long river crossing installed using horizontal direction drilling. The selected alignment considered several environmental, infrastructure and social issues and included both horizontal and vertical curves (a first for Manitoba). The project was commissioned safely, and the crossing is now effectively supporting the wastewater flows across the Red River in Winnipeg.
