The facility serves a population of approximately 2,321 residents in the Sainte Blandine district, operating under the regulatory framework of the Canadian Environmental Protection Act and provincial Quebec regulations. As a small-scale treatment plant, it is subject to Canadian wastewater standards that require secondary treatment for discharges into sensitive environments. The plant's designed capacity is 1.00 million liters per day, and it operates under permits issued by the Quebec Ministry of the Environment, which mandate compliance with effluent quality criteria to protect receiving waters. The plant's treated effluent discharges into the Saint Lawrence River watershed, ultimately reaching the Gulf of Saint Lawrence. This coastal region supports diverse aquatic life, including fish species such as Atlantic salmon and various migratory birds. The plant plays a key role in protecting the local marine environment from untreated sewage contamination.
