Overview
Bischwiller wastewater treatment plant serves approximately 57,000 people in Grand Est, France. It operates under the EU Urban Waste Water Treatment Directive, which mandates secondary treatment for agglomerations of this scale.
The Bischwiller wastewater treatment plant is located in the commune of Bischwiller, within the Bas-Rhin department of the Grand Est region in northeastern France. The facility serves a population of approximately 57,000, classifying it as a medium to large agglomeration under European Union regulations. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations with a population equivalent (PE) between 10,000 and 150,000 are required to have secondary treatment as a minimum. For sensitive areas, more stringent tertiary treatment may be necessary. The regulatory framework ensures compliance with national and EU standards. The treated effluent is discharged into the local watershed, which ultimately drains into the Rhine River basin. The Rhine is a major European waterway that flows through Germany and the Netherlands before reaching the North Sea. The plant plays a key role in protecting the water quality of the Rhine basin and the downstream aquatic ecosystems.
Environmental context
The Bischwiller plant discharges into the local water network that feeds into the Moder River, a tributary of the Rhine. The Rhine River flows through the Upper Rhine Valley, a region with diverse aquatic habitats and important migratory corridors for fish species. The plant's operations help maintain water quality in the Rhine basin, which supports agriculture, industry, and biodiversity downstream.
