MOGNEVILLE55 Wastewater Treatment Plant, Mognéville, Grand Est, France

MOGNEVILLE55 is an advanced wastewater treatment plant located in the commune of Mognéville, in the Meuse department of the Grand Est region, France. The plant serves a population of approximately 2,375 residents and has a designed capacity of 2,700 cubic meters per day, with a reported discharge volume of 423.70 cubic meters per day. As an advanced treatment facility, MOGNEVILLE55 goes beyond secondary treatment to remove nutrients such as nitrogen and phosphorus, which is typical for plants in sensitive areas under the EU Urban Waste Water Treatment Directive (91/271/EEC). The directive requires tertiary treatment for agglomerations of this size discharging into sensitive catchments, and France has designated many water bodies as sensitive under this framework. The plant discharges treated effluent into local watercourses that ultimately drain into the Ornain River, a tributary of the Marne, which flows into the Seine and then the English Channel. The Grand Est region is characterized by agricultural landscapes and the plant plays a key role in protecting downstream water quality and aquatic ecosystems.

MOGNEVILLE55 discharges into the Ornain River basin, which flows into the Marne River, a major tributary of the Seine. The Seine ultimately reaches the English Channel. The region's water bodies support diverse aquatic life and are subject to nutrient sensitivity, making advanced treatment crucial for preventing eutrophication in downstream rivers and coastal zones.
