DONCHERY Wastewater Treatment Plant, Villers-sur-Bar, Grand Est, France

The DONCHERY wastewater treatment plant is located in Villers-sur-Bar, a commune in the Ardennes department of the Grand Est region, France. The plant serves a population of 2,133 and is part of the municipal wastewater infrastructure for the area. It is situated along the Voie Verte Trans Ardennes near Condé, within the Sedan arrondissement. As an advanced treatment facility, DONCHERY provides a higher level of purification beyond secondary treatment, which is typical for plants in sensitive areas under the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant has a designed capacity of 3,800 m³/day and currently discharges 380.52 m³/day, indicating it operates well below its maximum capacity. French wastewater plants of this scale are regulated by the national water agencies and must comply with European standards for effluent quality. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Meuse River basin. The Meuse flows through the Ardennes region and into Belgium and the Netherlands before reaching the North Sea. The plant's advanced treatment helps protect the Meuse River and its downstream ecosystems, including sensitive aquatic habitats and water quality for communities relying on the river.

The DONCHERY plant discharges into the Meuse River basin, which flows through the Ardennes region and eventually reaches the North Sea. The Meuse supports diverse aquatic life and is an important migratory corridor for fish. Advanced treatment at this plant reduces nutrient loads and pollutants, helping to maintain water quality in the river and its downstream environments, including ecologically sensitive areas in the lower Meuse delta.
