The plant serves a population of 4,022 and is part of the municipal wastewater infrastructure for the area. As a Canadian facility, Etangs Nord operates under provincial and federal regulations, including the Quebec Environment Quality Act and the Canadian Environmental Protection Act. For a plant serving a small population, typical treatment involves primary or secondary processes to meet effluent standards. The plant's designed capacity is 1.00, indicating its scale. The plant discharges treated wastewater into the local watershed, which ultimately drains into Lac Saint-Jean and then via the Saguenay River to the St. Lawrence Estuary. This region supports diverse aquatic life and is ecologically sensitive, with the receiving waters contributing to the broader St. Lawrence ecosystem.

The plant's treated effluent enters the Lac Saint-Jean basin, which flows into the Saguenay River and eventually reaches the St. Lawrence Estuary. This watershed supports a variety of fish species and migratory birds, and the estuary is a critical habitat for marine mammals. The area is ecologically significant, and proper treatment helps protect water quality downstream.
