-$815 million contract award follows completion of collaborative development phase-
TORONTO, July 17, 2026 (GLOBE NEWSWIRE) -- Aecon Group Inc. (TSX: ARE) ("Aecon") announced today that Red River Biosolids Partners, an Aecon-led consortium with MWH Constructors and Oscar Renda Contracting, in which each partner holds a 33.3% interest, has completed the collaborative development phase and has been awarded an $815 million contract by the City of Winnipeg for the North End Water Pollution Control Centre (“NEWPCC”) Sewage Treatment Plant Upgrade – Biosolids Facilities progressive design-build project in Manitoba. Stantec is providing design services. Aecon’s share of the contract value will be added to its Construction segment backlog in the third quarter of 2026.
During the development phase, Red River Biosolids Partners advanced design and cost elements of the project. The construction phase will now begin to deliver new biosolids facilities and modifications to the existing facilities. Upgraded facilities operations are expected to commence in the fourth quarter of 2030, with final construction completion anticipated in the second quarter of 2031.
"The Winnipeg North End Sewage Treatment Plant is undergoing one of the largest water infrastructure upgrades in North America and this contract reflects the trust our clients place in Aecon to play an integral role in multiple stages of complex projects – harnessing decades of diverse industrial and water infrastructure experience,” said Jean-Louis Servranckx, President and Chief Executive Officer, Aecon Group Inc.
“The completion of the development phase demonstrates the effective collaboration between Aecon, our partners and the City of Winnipeg to advance this critical project that will significantly enhance efficiency and expand the plant’s operating capacity to serve growing populations,” said Thomas Clochard, Executive Vice President and Chief Operating Officer, Aecon Group Inc. “We look forward to carrying the momentum from our work on the plant’s Headworks Facilities project to drive safety and execution excellence during the construction phase.”
The plant is Winnipeg’s largest and oldest wastewater treatment facility, responsible for treating 70% of the city’s wastewater and all biosolids. The upgrades will help meet environmental regulations, protect waterways, and expand water treatment capacity, while supporting employment and economic growth.
