It serves the local community of approximately 1,929 residents, operating under the regulatory framework of the Canadian Environmental Protection Act and provincial Quebec regulations. The plant is classified as a small-scale facility, typical for rural agglomerations in the region.

The treated effluent is discharged into a local watercourse that drains into the Saint-François River basin, part of the larger St. Lawrence River watershed. This region supports diverse aquatic life and is important for recreational and ecological purposes. The plant's operations help protect downstream water quality in the St. Lawrence River system, which ultimately flows into the Gulf of St. Lawrence.

The plant discharges into a local tributary within the Saint-François River basin, which flows into the St. Lawrence River and eventually the Gulf of St. Lawrence. This watershed supports a variety of fish species and is used for recreation. The plant's secondary treatment helps reduce nutrient and organic pollution, protecting downstream ecosystems in this sensitive freshwater system.
