Lake Manitoba and Lake St. Martin Outlet Channels
Following severe flooding events in 2011 and 2014, the Province of Manitoba retained KGS Group for the design of the Lake Manitoba and Lake St. Martin Outlet Channels Project. The outlet channels will serve as new, permanent flood control infrastructure for both lakes.
Completed under tight schedule restrictions, the conceptual design work involved:
- Remote field investigations
- Extensive review and analysis of the various channel configurations
- Preparation of concept designs, cost estimates and constructability reviews
- Identification, assessment and screening of potential environmental and socio-economic impacts
The diverse range of design components and unique site conditions resulted in a challenging engineering undertaking that was successfully managed by the multidisciplinary team of experienced engineers, GIS technicians and support staff assembled by KGS Group.
KGS Group subsequently completed the preliminary, final design and tender preparation for the outlet channel from Lake St. Martin to Lake Winnipeg. The project includes roughly 23 km of channel excavation, multiple drop structures, and construction of a water control structure near the channel inlet complete with gates, hoists, bridge deck and ancillary buildings. The total estimated budget for this portion of the project is over $300 million. The construction phase of the project is pending regulatory approval.
Once constructed, the outlet channels are projected to maintain both lakes below flood stage over 99 per cent of the time. They will provide the ability to better regulate the lakes and reduce the impact of future floods, benefiting residents and businesses in the area.
Project Highlights
- Design for 23 km of channel excavation with defined sections and earthworks quantities
- Design of multiple drop structures sized for hydraulic control and energy dissipation
- Water control structure near the channel inlet for operational regulation
Pointe du Bois Spillway Replacement

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
Cote First Nation Solid Waste Transfer Station
Cote First Nation had been experiencing significant solid waste management challenges including inconsistent collection services and unmanned and non-engineered dump sites throughout the Reserve. Additionally, the main landfill site was note engineered which posed a significant risks to the surrounding soil and groundwater.
To ensure waste was being managed in a sustainable manner, Cote First Nation engaged KGS Group to review their waste management practices and design and oversee the construction of a new solid waste transfer station. We also supported community engagement events to share the importance of transfer stations and responsible waste management practices.
During construction, nearly 2,000 hours were completed by Cote First Nation members, and the total value of purchased material, worker wages and equipment rentals from the Nation was approximately $126,500. This project also presented on-the-job training and mentorship opportunities for members of Cote First Nation and was seen as a community-driven process that was mutually beneficial to everyone.
