Overview
Station d'épuration St-Hermas is a secondary treatment plant serving 381 people in Mirabel, Québec, Canada. It discharges treated wastewater into local waterways.
Station d'épuration St-Hermas is a municipal wastewater treatment facility located at 4750 Chemin Laurin in the Saint-Hermas sector of Mirabel, Québec, Canada. It serves a small population of 381 residents, reflecting the rural character of the area within the Laurentides region. The plant provides secondary treatment, which is the standard biological treatment level required under Canadian federal and provincial regulations for communities of this size. In Canada, wastewater treatment is governed by the Wastewater Systems Effluent Regulations (WSER) under the Fisheries Act, which mandate secondary treatment or equivalent for most systems. The plant's discharge volume is 171.00 cubic meters per day. The treated effluent is released into the local watershed, which ultimately drains into the Ottawa River via the Rivière du Nord or other tributaries. The Ottawa River flows into the St. Lawrence River, a major waterway that supports diverse aquatic ecosystems and serves as a critical corridor for fish migration, including species like the American eel and lake sturgeon.
Environmental context
The plant discharges into the Rivière du Nord watershed, which flows into the Ottawa River and then the St. Lawrence River. The St. Lawrence River is a major ecological corridor supporting diverse fish populations and migratory birds. The region's aquatic habitats are sensitive to nutrient loading and contaminants, making effective secondary treatment important for protecting downstream water quality.
