For small communities like Saint-Eugene-de-Guigues, secondary treatment is the standard to protect receiving waters. The plant's discharge volume of 103.00 cubic meters per day indicates its modest scale, typical for a small agglomeration. The treated effluent from Etang Non Aere flows into local streams that drain into the Ottawa River watershed, eventually reaching the St. Lawrence River and the Atlantic Ocean. This downstream connection underscores the plant's role in protecting water quality in a region known for its lakes and rivers, supporting aquatic ecosystems and recreational uses.

The plant discharges into small watercourses within the Ottawa River basin, which flows into the St. Lawrence River and ultimately the Atlantic Ocean. The region's watershed supports diverse aquatic life, including fish species such as walleye and pike, and is important for local biodiversity. Protecting water quality through secondary treatment helps maintain the ecological health of these downstream environments.
