MAUZE SUR LE MIGNON LES BRANDES Wastewater Treatment Plant, Cram-Chaban, France

MAUZE SUR LE MIGNON LES BRANDES is an advanced wastewater treatment plant located in Cram-Chaban, within the Nouvelle-Aquitaine region of western France. The facility serves a population equivalent of approximately 2,471 and is situated inland, more than 10 km from the coast but within 50 km of the Atlantic Ocean. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 3,500 m³/day and a discharge volume of about 441 m³/day, the plant operates well within its capacity, ensuring effective treatment of municipal wastewater. The treated effluent is discharged into local watercourses that drain into the Atlantic Ocean via the Mignon River and the Sèvre Niortaise basin. This region supports diverse aquatic life and contributes to the ecological health of the Marais Poitevin, a vast wetland area of ecological importance. The plant's advanced treatment helps protect these sensitive downstream environments.

The plant discharges into the Mignon River, a tributary of the Sèvre Niortaise, which flows into the Atlantic Ocean near the Marais Poitevin. This wetland is an ecologically sensitive area that supports diverse bird species and aquatic life. Advanced treatment at the plant helps reduce nutrient loads, protecting the downstream ecosystem from eutrophication.
