CHATENOIS Vosges Wastewater Treatment Plant, Châtenois, Grand Est

CHATENOIS Vosges is an advanced wastewater treatment plant located in Châtenois, in the Grand Est region of France. The plant serves a population of approximately 5,260 people, reflecting its role as a medium-sized municipal facility in the Vosges department. Its advanced treatment level ensures high-quality effluent suitable for discharge into sensitive environments. The plant operates under the European Union's Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. As an advanced treatment facility, it likely incorporates nutrient removal to protect receiving waters from eutrophication. The designed capacity of 5,916 m³/day indicates the plant is sized to handle current and future flows, with a reported discharge volume of 938.37 m³/day. The treated effluent is discharged into local watercourses that ultimately drain into the Meuse River basin. The Grand Est region is characterized by a mix of agricultural and forested landscapes, and the plant's advanced treatment helps protect downstream aquatic ecosystems. By maintaining high treatment standards, the facility contributes to the ecological health of the region's rivers and groundwater.

The plant discharges into local streams that flow into the Meuse River basin, which eventually reaches the North Sea. The surrounding watershed supports diverse aquatic life and is important for regional biodiversity. Advanced treatment helps minimize nutrient loading, protecting downstream habitats from eutrophication and maintaining water quality for both ecological and human uses.
