WEISLINGEN Wastewater Treatment Plant | Weislingen, Grand Est, France

The WEISLINGEN wastewater treatment plant is located in the commune of Weislingen in the Bas-Rhin department of Grand Est, France. It serves a population of approximately 1,700 residents, making it a small-scale municipal facility. The plant is situated in the rural Vosges du Nord region, near the village of Tieffenbach. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Its designed capacity is 3,000 m³ per day, with an actual discharge volume of 303.28 m³ per day, indicating significant spare capacity. As a French facility, it operates under national regulations transposing EU directives, with permits issued by the local water agency (Agence de l'Eau). The treated effluent is discharged into a local watercourse that ultimately drains into the Rhine River basin. The plant plays a key role in protecting the sensitive aquatic ecosystems of the Vosges du Nord, an area known for its forests and streams. By providing advanced treatment, it helps maintain water quality in the region's surface waters.

The plant discharges into a small stream that flows into the Moder River, a tributary of the Rhine. The Rhine basin is a major European waterway supporting diverse aquatic life and providing drinking water for millions. The Vosges du Nord region features sandstone geology and forested catchments, making it sensitive to nutrient pollution. Advanced treatment at this plant helps protect downstream ecosystems, including the Rhine's floodplain habitats.
