In Canada, wastewater treatment is regulated by provincial authorities; Quebec's Environment Quality Act and the Regulation on Wastewater Treatment Works set effluent standards. For small communities like Beaulac-Garthby, secondary treatment ensures adequate removal of organic matter and suspended solids before discharge. The treated effluent is discharged into local waterways that ultimately drain into the St. Lawrence River via the Chaudière River basin. The St. Lawrence River is a major ecological corridor supporting diverse aquatic life and migratory fish species. The plant's inland location reduces direct marine impact, but its discharge contributes to the overall water quality of the regional watershed.

The plant discharges into the Chaudière River watershed, which flows northward into the St. Lawrence River near Quebec City. The St. Lawrence River is a vital freshwater ecosystem supporting fish populations such as Atlantic sturgeon and American eel, and serves as a migratory route for birds. The plant's secondary treatment helps protect downstream water quality in this ecologically significant river system.
