Cornwall Wastewater Treatment Plant

One of the City of Cornwall's largest responsibilities involves the collection and treatment of wastewater. This is accomplished through an extensive sewer network and a primary Wastewater Treatment Plant and pumping station on Montreal Road in the east end of the City.

The City of Cornwall strives to maintain high standards in wastewater treatment to ensure there is minimum effect on the St. Lawrence River.

Originally built in 1968, Cornwall's Wastewater Treatment Plant currently serves approximately 46,000 residents as well as numerous commercial and industrial customers. The plant has an average rated capacity of 54,000 cubic metres per day and a peak design capacity of 108,000 cubic metres per day.

The plant is currently undergoing a series of upgrades as part of a $55.5 million construction project, the largest capital project in the City's history.
