COULONGES SUR L AUTIZE is an advanced wastewater treatment plant located in Coulonges-sur-l'Autize, a commune in the Deux-Sèvres department of Nouvelle-Aquitaine, France. The plant serves a population of 1,204 and has a designed capacity of 3,000 m³/day, with an average discharge volume of 214.79 m³/day. As an advanced treatment facility, it goes beyond the secondary treatment requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The plant's advanced treatment likely includes nutrient removal, which is important for protecting sensitive water bodies. The plant discharges treated wastewater into the local watershed, which drains into the Sèvre Niortaise river and eventually into the Bay of Biscay. This region supports diverse aquatic life and is part of the Marais Poitevin, an ecologically significant wetland area.
Environmental context
The plant discharges into the local watershed that feeds the Sèvre Niortaise river, which flows into the Bay of Biscay. The downstream environment includes the Marais Poitevin, a large wetland area that supports diverse bird species and aquatic life. Advanced treatment helps reduce nutrient loading, protecting this sensitive ecosystem from eutrophication.
