Cote First Nation Fence Post Treatment Site Remediation







Cote First Nation is located north of Kamsack, Saskatchewan, and within the Reserve boundaries was a former fence post treatment facility that operated for approximately 10 seasons before closing in the late 1980s. The facility used chemicals to preserve the wood that can have adverse effects on humans, animals and the environment in certain concentrations. The site of the former facility is located within Badgerville near residences and gathering places, posing a concern for the Cote First Nation Council and its members.
Over several years, KGS Group conducted environmental assessments and oversaw the remediation of the former facility site. For the first time in approximately 45 years, the contaminated soils associated with the facility, were fully remediated.
Notably, as part of the project, an impressive 9,000 person-hours of work were completed by personnel from the Cote First Nation. The total value of purchased local borrow materials, worker wages and equipment rentals supplied by the First Nation was approximately $843,000. Executed in the spirit of the Truth and Reconciliation Commission Calls to Action, the project presented on-the-job training and mentorship opportunities for the Cote First Nation. Overall, the project was a collaborative process that was mutually beneficial to all parties and was largely successful because of the local Nation’s involvement.
With the site of the former facility now safely remediated, the Cote First Nation can begin planning for future development in the area. What was once a potential hazard, is now a place of great possibility.

Mayo B Hydro Enhancement Project




KGS Group was retained by the Yukon Energy Corporation to review feasible hydro projects in the territory, which culminated in the selection of the Mayo B project. To develop the $120 million Mayo B, KGS entered into an early contractor involvement alliance partnership, sharing the financial risks and project rewards. This partnership was the first of its kind in the Canadian hydroelectric industry.
We conducted a feasibility study as well as completed the preliminary and final design of a new powerhouse downstream of the existing Mayo hydroelectric development. Reusing the already in-place dam and intake structure, the work also included connecting and conveying water to the new powerhouse through a new 3.8 km tunnel and penstock system.
Overcoming challenging conditions to make way for the new tunnel and “tie it” into 60-year old infrastructure, we used careful mapping and characterization. This helped support concurrent tunnel design and excavation, and slope stabilization. Precision LiDAR 3-D survey techniques and modelling were also integral to the work.
Within a remote, sub-arctic climate, KGS was also responsible for on-site construction management including all contract administration and quality assurance for the civil, mechanical and electrical works, as well as the supply and installation of the turbines and generator equipment.
As a result, total hydro power generation capacity went from 5.4 MW to 12 MW, increasing Yukon’s renewable and sustainable electricity generation capability. The on-budget, on-schedule project also displaces diesel generation, offsetting up to $10 million in annual fuel costs and eliminating approximately 25,000 tonnes of greenhouse gas emissions per year.

Pauingassi First Nation Landfill Expansion






Pauingassi First Nation is located in eastern Manitoba, approximately 275 km northeast of Winnipeg, on a peninsula of land that extends southward into Fishing Lake. At the time, the community had a total registered population of 668 and did not have an airport or an all-season road for access and uses winter roads, float planes or helicopters depending on the time of year.
Because access is primarily by winter road, numerous challenges must be overcome for solid waste management and in general for any construction projects in the community. Some of these challenges include heavy equipment access, difficulty removing divertible wastes from the community to proper disposal depots, dependency (and variability) of ice thickness, and overall higher construction costs compared to other, more easily accessible communities.
KGS Group created a new integrated resource management centre for this remote community. Success was achieved even though the COVID-19 pandemic and 2021 forest fires impacted the schedule. An innovative design overcame challenging site conditions, integrated community requests, preserved local heritage resources and Traditional Land Use Areas, and mitigated existing environmental impacts.
The result is a practical, environmentally sound, sustainable and aesthetically pleasing waste management facility that also addresses waste diversion. This project is a model for successful collaboration between Indigenous communities, contractors, consulting companies and government agencies.
Project Highlights
- Community‑informed planning, design and construction oversight
- Remote delivery adapted to winter road logistics
- Engineered facility to centralize waste handling and address diversion
- Design aligned with site constraints while preserving heritage and Traditional Land Use Areas
- A cleaner, safer community environment
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
