The plant discharges into the Allier River, which flows northward to join the Loire River near Nevers. The Loire is the longest river in France and drains into the Atlantic Ocean. The Allier River valley is ecologically sensitive, supporting diverse aquatic habitats and migratory fish species. The region's volcanic soils and agricultural land use influence local water quality.
