Collingwood WWTP

Ontario’s first biogas-powered microturbine CHP system installed at a wastewater treatment plant.

Ontario Wastewater Plant Uses Biogas Microturbine CHP for Energy Savings and Carbon Reduction

The microturbine uses digester gas to create electricity which is fed back into the plant behind the utility meter, reducing the amount of electricity needed at the WWTP. This project reduces the carbon footprint of the WWTP and is a beneficial way to utilize digester gas that is produced from the treatment process. Vergent supplied the CHP system and the biogas conditioning system. This combined project received approval in 2016 for Small Communities Funding, a funding partnership between the Government of Canada, the Province of Ontario and the Town of Collingwood.
