One of Calgary’s three wastewater treatment plants, Bonnybrook is undergoing an expansion with the plant estimated to be able to service an additional equivalent population of 325,000 people. When construction is completed in 2022, the facility will service a population of 1.366 million people.
The Plant D expansion is the largest project of the overall upgrade and includes new primary and secondary clarifiers, new bioreactors with biological nutrient removal system, new treated effluent filtration facility, new Thermal Hydrolysis Process facility, and a new flood berm. The City is also upgrading the existing ultraviolet disinfection system, digesters, and primary sludge thickening systems.
Three significant construction projects got underway in 2019: the primary treatment expansion, new biogas storage facility, and the cogeneeration facility expansion. Work was also done on the emergency outfall channel.
