COURCON Wastewater Treatment Plant, Courçon, Nouvelle-Aquitaine, France

The COURCON wastewater treatment plant is located in Courçon, a commune in the Charente-Maritime department of Nouvelle-Aquitaine, southwestern France. It serves a population of approximately 2,383 residents, classifying it as a small agglomeration under French and EU regulations. The plant employs advanced treatment processes, ensuring high-quality effluent. With a designed capacity of 2,500 m³/day and a current discharge volume of 425.12 m³/day, it operates well within its capacity. As a French facility, it complies with the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for discharges into sensitive areas. The treated effluent is discharged into local watercourses that ultimately drain into the Atlantic Ocean via the Pertuis d'Antioche. The plant plays a key role in protecting the region's aquatic ecosystems, including the nearby Marais Poitevin wetlands, by reducing nutrient and pollutant loads.

The plant discharges into the local watershed that flows through the Marais Poitevin, one of France's largest wetlands, before reaching the Atlantic Ocean via the Pertuis d'Antioche. This area supports diverse aquatic life and migratory birds, making nutrient removal critical to prevent eutrophication. The advanced treatment helps maintain water quality in this ecologically sensitive region.
