Maxville Sewage Works - North Glengarry, Ontario Wastewater Treatment Plant

Maxville Sewage Works is a municipal wastewater treatment facility located on Athol Road in North Glengarry, Ontario, within the Stormont, Dundas and Glengarry Counties. Serving a small population of 557 residents, the plant is part of Canada's decentralized wastewater infrastructure for rural communities. As an operational facility, it plays a key role in managing local sewage and protecting public health. Under Ontario's regulatory framework, small wastewater systems like Maxville Sewage Works are subject to the Ontario Water Resources Act and Environmental Protection Act. Plants serving fewer than 1,000 people typically employ lagoon-based or mechanical treatment systems designed to meet provincial effluent standards. The facility's capacity and discharge volume are managed to comply with local permits issued by the Ontario Ministry of the Environment, Conservation and Parks. The plant's treated effluent is discharged into a local watercourse that drains into the South Nation River, a tributary of the Ottawa River, which ultimately flows into the St. Lawrence River. This watershed supports diverse aquatic life and is an important ecological corridor in Eastern Ontario. The plant's operation helps maintain water quality in this sensitive river system, which is used for recreation and supports local biodiversity.

The plant discharges into a local tributary of the South Nation River, which flows into the Ottawa River and then the St. Lawrence River. This watershed is part of the larger Great Lakes-St. Lawrence basin, supporting diverse fish species and migratory birds. The area's agricultural land use means nutrient management is critical to prevent eutrophication in downstream waters.
