Station d epuration des eaux usees - Sainte-Angèle-de-Monnoir, Quebec Wastewater Treatment Plant

Station d epuration des eaux usees is a municipal wastewater treatment plant located in Sainte-Angèle-de-Monnoir, a small community in the Montérégie region of Quebec, Canada. The plant serves a population of approximately 909 residents and operates under secondary treatment standards, which is typical for small agglomerations in the province. As a secondary treatment facility, the plant employs biological processes to remove organic matter and suspended solids from wastewater. The plant's discharge volume is 408.00 cubic meters per day, reflecting the scale of the community it serves. In Quebec, such facilities are regulated under provincial environmental laws that align with the Canada-wide standards for wastewater effluent quality. The treated effluent is discharged into local waterways that eventually drain into the Richelieu River, a major tributary of the St. Lawrence River. The Richelieu River supports diverse aquatic life and is an important migratory corridor for fish species. The plant's operations help protect the downstream ecosystem from nutrient pollution and pathogens.

The plant discharges treated wastewater into local streams that flow into the Richelieu River, which then empties into the St. Lawrence River near Sorel-Tracy. The Richelieu River watershed supports a variety of fish species, including walleye and yellow perch, and provides habitat for waterfowl. The St. Lawrence River is a major ecological corridor in North America, and maintaining water quality in its tributaries is critical for the health of the entire estuary.
