AECON CONSORTIUM AWARDED CONTRACT FOR THE WINNIPEG NORTH END SEWAGE TREATMENT PLANT UPGRADE - BIOSOLIDS FACILITIES PROGRESSIVE DESIGN-BUILD PROJECT

Red River Biosolids Partners, an Aecon Group Inc.-led consortium with MWH Constructors Canada Ltd. and Oscar Renda Contracting of Canada Inc., in which each partner holds a 33.3-per-cent 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 of Aecon Group.

"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 of Aecon Group. "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 waste water treatment facility, responsible for treating 70 per cent of the city's waste water and all biosolids. The upgrades will help meet environmental regulations, protect waterways and expand water treatment capacity while supporting employment and economic growth.

Water is a critical resource with significant requirements for continuing investment, and Aecon is a leading delivery partner with expertise from over 300 water infrastructure projects. Aecon's sector experience includes the continuing Red-Seine-Rat waste water treatment facility in Manitoba, the Giant Mine remediation project in Northwest Territories and the Buffalo Pound water treatment plant project in Saskatchewan. Aecon also completed the Regina waste water treatment plant in Saskatchewan and the Annacis Island waste water treatment plant and Comox Valley Water treatment plant projects in British Columbia. Aecon's portfolio of work in the United States through Bodell Construction, an Aecon company, includes the continuing Green River waste water treatment plant replacement in Wyoming, recently awarded work at the Walnut Creek waste water treatment facility in Texas and the Duchesne Valley water treatment plant project delivered in Utah.

Further information about the project is available on the City of Winnipeg's website.
