This project aims to replace the aging incinerators at the Jean-R.-Marcotte wastewater treatment plant, thereby reducing CO2 emissions and improving the efficiency of wastewater treatment.

The City of Montreal is committed to an ambitious project to modernize the Jean-R.-Marcotte wastewater treatment plant, located at the eastern end of the island.

This plant, which processes nearly half of Quebec's wastewater, is one of the largest in the world. After decades of service, its four incinerators, in operation since 1988, are reaching the end of their useful life. They are less reliable and more costly to maintain, requiring frequent and expensive repairs.

The refurbishment project includes the construction of a new sludge treatment and recovery plant (UTVB), which is scheduled to be operational in 2033. Initially estimated at 700 million dollars in 2023, the project's cost is now projected to be 1.2 billion dollars.

Currently in the preliminary engineering phase, the construction of the plant will follow that of the ozone water disinfection unit, planned for 2028 after several delays and cost overruns.

This modernization project is crucial for the City of Montreal, not only to improve the efficiency of wastewater treatment but also to reduce the carbon footprint of its municipal activities.

The Jean-R.-Marcotte wastewater treatment plant, with its incinerators responsible for about 25% of the CO2 emissions of the Montreal agglomeration, requires an upgrade to continue to effectively serve the population.

By investing in this new plant, Montreal demonstrates its commitment to sustainability and improving the quality of life for its residents.

The renovation project of the Jean-R.-Marcotte wastewater treatment plant is a significant step towards a greener and more efficient future for the city's wastewater management.
