Newton Force Main River Crossing
KGS Group and Associated Engineering designed and oversaw the construction of a new, 466 meter river crossing installed trenchlessly 40 meters below grade to replace the failing Newton Force Main River Crossing. This vital piece of infrastructure supports the wastewater flows from the entire Hawthorne sewer district in Winnipeg. Under dry weather conditions, the Newton Force Main River Crossing transports over 2.3 million litres of wastewater daily under the Red River.
The existing crossing was installed along the river bottom in 1978 and was connected to lands that have become densely urbanized, which limited solutions. An alternate alignment was developed to both reroute the force main and install it safely within the bedrock strata below the river.
The result is a durable, long‑term asset that improves system resilience and safeguards the environment and the community.
Project Highlights
- 466 meter river crossing installed trenchlessly, 40 meters below grade
- Horizontal directional drilling with horizontal and vertical curves – a first in Manitoba
- 780 meters of new force main on an alternate alignment in bedrock below the river
- Replaces 1978 river‑bottom crossing which lowers environmental risk and maintenance needs
