Improvements to aging wastewater treatment infrastructure to better serve the growing Toronto population

Alberici Humber Wastewater Treatment Plant Construction Concrete

Complex refurbishment of aging infrastructure

Aging infrastructure and a growing population require major upgrades to one of the largest wastewater treatment plant in Ontario. Alberici is refurbishing and replacing secondary treatment process equipment at the Humber Wastewater Treatment Plant. The project also includes major upgrades to existing buildings, process enhancements, and new construction.

Refurbishment of the secondary treatment area

Project scope includes the removal and replacement of five aeration tanks, final clarifiers, service tunnels, piping, pumps, and electrical systems. Along with the extensive upgrades, a new electrical building and effluent pump station will be constructed. Alberici will be performing all commissioning for new aeration, clarifiers, electrical equipment, process piping, and chemical systems.

Maintaining plant operations

The existing 50-year-old plant must remain fully operational 24 hours per day during construction. Alberici is constructing temporary buildings and systems to maintain plant operations during the renovation.
