The City of Winnipeg has awarded an $815-million construction contract to a consortium led by Aecon Group Inc. for a significant upgrade of the Winnipeg North End Sewage Treatment Plant, the municipality's largest and oldest wastewater facility.
Who is involved and the work timeline
The project will be delivered by the Red River Biosolids Partners consortium, composed of Aecon, MWH Constructors and Oscar Renda Contracting, with each partner holding an equal 33.3 per cent interest. Stantec is providing design services for the upgrade.
- Contract value: $815 million
- Consortium partners: Aecon, MWH Constructors, Oscar Renda Contracting (each 33.3%)
- Designer: Stantec
- Operations begin: fourth quarter of 2030
- Final construction completion: second quarter of 2031
"the city's largest and oldest wastewater treatment facility"
Local effects and regulatory aims
City officials say the upgrade is intended to ensure the plant complies with environmental regulations, to better protect surrounding waterways and to increase the plant's treatment capacity. For residents, that means the project is aimed at reducing the environmental risk associated with an ageing facility and improving the long-term reliability of wastewater services.
Delivering large infrastructure work of this scale involves years of planning and staged construction. The timeline provided places the start of operations for upgraded facilities in the late months of 2030, with full construction wrapping up by mid‑2031. During that period, residents and nearby communities can expect ongoing construction activity and staged commissioning of new treatment components.
Project oversight and next steps
Stantec's role as design services provider means detailed engineering and design oversight will guide construction. The equal-share structure among the three construction partners allocates project risk and responsibilities across the consortium. Municipal oversight will continue through permitting, environmental compliance checks and construction inspections as the work proceeds toward the 2030–2031 milestones.
| Milestone | Date |
|---|---|
| Operations of upgraded facilities begin | Q4 2030 |
| Final construction completed | Q2 2031 |
The financial scale of the contract and the prominence of the North End plant mean the project will be a major element of Winnipeg's infrastructure spending in the coming years. Residents and local stakeholders will be watching for construction impacts, timelines for staged work, and how the upgrades affect environmental outcomes for the city's waterways.
