The plant discharges into the Vesle River, which flows into the Aisne River, a major tributary of the Oise and Seine rivers, ultimately reaching the English Channel. The Vesle River supports diverse aquatic life and is part of a sensitive watershed that requires effective nutrient removal to prevent eutrophication downstream. The plant's location in the Grand Est region, an area with mixed agricultural and urban land use, underscores its importance in maintaining water quality in the Seine basin.
