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.

Project Highlights

• Environmental assessments over multiple seasons to delineate impacts and guide remediation
• Remediation of contaminated soils within the former facility footprint
• Tissue sampling on vegetation within the impacted area to confirm no uptake by trees
• Supply and placement of local borrow materials for backfill and site restoration
• Site regrading and cleanup to stabilize surfaces and improve near‑term usability
• Community engagement, on‑site training and mentorship delivered by KGS Group
• More than 9,000 hours completed by Cote First Nation personnel
• $843,000 in materials, wages and equipment rentals from within Cote First Nation

The Central Manitoba Mine, an abandoned mine site in Nopiming Provincial Park, was a top remediation priority for the Province of Manitoba because of the presence of major hazards to the public and environment. The site contained acid-generating tailings, waste rock, abandoned infrastructure and unsafe mine openings that lead to a network of underground mine development.

KGS Group spearheaded the site’s transformation. This project involved the development of comprehensive closure plans, the design of innovative remediation solutions, and construction administration.

The result: public safety was ensured, health hazards eliminated, and the site was restored to satisfactory conditions, mitigating extensive contamination and environmental risks.

Project Highlights

• Site assessment, risk evaluation and closure planning
• Containment and treatment of acid‑generating tailings and waste rock
• Securing unsafe mine openings, decommissioning abandoned infrastructure and debris removal
• Construction administration, contractor oversight and regulatory coordination

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

The Pointe du Bois Generating Station is the oldest operating hydroelectric plant in Manitoba. Despite extensive upgrades and ongoing maintenance over the years, the original spillway required replacement. The Pointe du Bois Spillway Replacement project included the design and construction of a new remotely operated 7-bay spillway and a new 1km long zoned earthfill dam, complete with an ancillary support building for electrical switch gear and control systems, a backup diesel generator, and other related infrastructure.

As the prime consultant, KGS Group worked collaboratively with Manitoba Hydro as the designer in an early contractor involvement project delivery process. KGS also provided full-time technical support and quality assurance assistance through construction, commissioning and close-out activities.

The final design was carried out entirely within a 3D digital environment, and was paramount for the successful execution of all stages of the project. This innovative approach gave the team the ability to visualize the end product at the design stage and enabled harmonious advancement of the project across multiple disciplines.

The several hundred-million-dollar project was successfully completed without any interruptions to the ongoing operation of the plant, while protecting and preserving established lake sturgeon habitat and restoring the natural landscape in this environmentally sensitive provincial park setting.

The flood of 2011 highlighted several potential “weak links” in Manitoba’s flood control system, which resulted in widespread damage across the province. To address the propensity for flooding in the Assiniboine River and Lake Manitoba basins, KGS Group carried out a flood mitigation study, which identified major flood vulnerabilities and assessed a wide range of measures to improve protection in the region.

A vast amount of data was reviewed and over 70 mitigation options were evaluated including dikes, reservoirs, diversion channels, wetland restoration and development controls. As well, a number of sophisticated models were developed to calculate cost-benefit ratios and the economic viability of the options.

Working collaboratively with Manitoba Transportation and Infrastructure, the project team developed a technical workshop and held public open house events to incorporate important feedback into the study findings.

The results of the study identified over $1 billion of flood mitigation upgrades required to increase the flood protection level to provincial standards across the basin. The results will also serve as the foundation for major flood mitigation programs for the next several decades.

Project Highlights

• Reviewed and synthesized basin‑wide datasets to establish current and future flood risk profiles
• Evaluated 70+ mitigation options, including dikes and levees, reservoirs and storage, diversion channels, wetland restoration, development controls
• Compiled actionable study deliverables for program planning
