Epuration Cabano Wastewater Treatment Plant, Témiscouata-sur-le-Lac, Québec

Epuration Cabano is a municipal wastewater treatment plant located in Témiscouata-sur-le-Lac, in the Bas-Saint-Laurent region of Québec, Canada. The plant serves a population of approximately 2,809 residents, providing essential wastewater treatment services to the community. As a small-scale facility in Canada, the plant is subject to the federal Wastewater Systems Effluent Regulations (WSER) under the Fisheries Act, which set national effluent quality standards. Provincially, Québec's Regulation respecting municipal wastewater treatment works (REAFIE) governs design and operation. For a plant of this size, secondary treatment is typically required to meet effluent standards. The plant discharges treated effluent into the local watershed, which ultimately drains into the Saint Lawrence River via the Madawaska River and Lake Témiscouata. The Saint Lawrence River is a major waterway supporting diverse aquatic life and serving as a critical migratory corridor for fish species. Proper treatment helps protect downstream water quality and ecosystem health.

The plant's treated effluent enters the local watershed, flowing into Lake Témiscouata and then via the Madawaska River to the Saint Lawrence River. The Saint Lawrence River is a major ecological corridor supporting diverse fish populations, including Atlantic salmon and American eel, and provides critical habitat for migratory birds. Protecting water quality in this system is essential for maintaining biodiversity and supporting recreational and commercial fisheries.
