Bassin d epuration Wastewater Treatment Plant, Kingsey Falls, Quebec

Bassin d epuration is a wastewater treatment plant located in Kingsey Falls, Quebec, Canada. The plant serves a small community of approximately 1,964 residents and is situated in the Centre-du-Quebec region. It is classified as a small agglomeration under Canadian wastewater regulations. As a small-scale facility, the plant is expected to provide secondary treatment in accordance with the Wastewater Systems Effluent Regulations (WSER) under the Canadian Environmental Protection Act. These regulations set national standards for effluent quality to protect fish habitat and human health. The plant's operational status is active, ensuring continuous treatment of municipal wastewater. The plant discharges treated effluent into the local watershed, which ultimately drains into the St. Lawrence River via the Nicolet River system. The St. Lawrence River is a major waterway that supports diverse aquatic life and provides drinking water for millions. The plant's proximity to the coast (within 10 km) means its discharge can influence estuarine and marine environments.

The plant's treated effluent enters the local drainage network, which flows into the Nicolet River and then into the St. Lawrence River. The St. Lawrence River is a critical ecosystem supporting fish species such as Atlantic sturgeon and American eel, and it serves as a migratory corridor for waterfowl. The plant's coastal location means that nutrient and pollutant loads can affect the St. Lawrence Estuary, a biologically productive area.
