MAULEON LA TOUCHE SALBOEUF Wastewater Treatment Plant, Mauléon, France

The MAULEON LA TOUCHE SALBOEUF wastewater treatment plant is located in Mauléon, within the Deux-Sèvres department of Nouvelle-Aquitaine, France. This facility serves a small community of approximately 1,960 residents, providing advanced treatment to protect local water quality. As an advanced treatment plant, it goes beyond secondary treatment to remove nutrients and other pollutants, meeting stringent French and EU standards. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), plants serving agglomerations under 10,000 population equivalent are typically required to provide secondary treatment, but this plant's advanced level indicates a commitment to higher environmental protection, possibly due to a sensitive receiving environment. The plant discharges treated wastewater into local watercourses that eventually drain into the Atlantic Ocean via the Loire River basin. By employing advanced treatment, the plant helps safeguard downstream aquatic ecosystems and supports the ecological health of the region's rivers and coastal waters.

The plant's treated effluent enters local streams that flow into the Sèvre Nantaise river, a tributary of the Loire River. The Loire basin is one of France's largest and most ecologically significant watersheds, supporting diverse fish populations and migratory species. Advanced treatment at this plant reduces nutrient loading, helping to prevent eutrophication in downstream waters and protecting the sensitive estuarine and coastal environments of the Atlantic.
