Environmental context
The plant discharges into the Garonne River basin, which flows through southwestern France to the Gironde estuary and the Atlantic Ocean. The Garonne supports diverse aquatic life and is an important migratory corridor for Atlantic salmon and European eel. Advanced treatment reduces nutrient loading, helping to prevent eutrophication in downstream coastal waters.
