Etangs aeres Saint Bruno Wastewater Treatment Plant, Saint-Bruno-de-Kamouraska, Quebec

Etangs aeres Saint Bruno is a municipal wastewater treatment facility located in Saint-Bruno-de-Kamouraska, a small community in the Bas-Saint-Laurent region of Quebec, Canada. The plant serves a population of 118 and operates under secondary treatment, which is appropriate for its small scale. As a secondary treatment plant, it uses biological processes to reduce organic matter and suspended solids, meeting Canadian federal and provincial standards for wastewater effluent. The plant's discharge volume is 53.00 cubic meters, reflecting the low flow from the small population served. Canadian regulations under the Wastewater Systems Effluent Regulations (WSER) set national performance standards for effluent quality, which this facility is expected to meet. The treated effluent is discharged into the local watershed, which ultimately drains into the St. Lawrence River, a major waterway that flows into the Gulf of St. Lawrence and the Atlantic Ocean. The plant plays a key role in protecting the St. Lawrence River ecosystem from nutrient pollution and pathogens, supporting aquatic life and downstream communities.

The plant discharges into a tributary of the St. Lawrence River, which flows into the Gulf of St. Lawrence and the Atlantic Ocean. The St. Lawrence River is a critical habitat for fish species such as Atlantic sturgeon and American eel, and its estuary supports diverse marine life. The plant's secondary treatment helps reduce nutrient loading and protect water quality in this ecologically sensitive watershed.
