PLOBSHEIM Wastewater Treatment Plant, Plobsheim, Grand Est, France

PLOBSHEIM is a municipal wastewater treatment plant located in Plobsheim, a commune in the Bas-Rhin department of the Grand Est region, France. The facility serves a population of approximately 3,400 residents, placing it in the small agglomeration category under French regulations. The plant operates with secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. Its designed capacity is 3,300 cubic meters per day, and the current discharge volume averages 606.55 cubic meters per day, indicating available treatment capacity. The treated effluent is discharged into local waterways that ultimately drain into the Rhine River basin. The Rhine is a major European waterway supporting diverse aquatic ecosystems and providing drinking water for millions. The plant's secondary treatment helps protect downstream water quality in this ecologically significant river system.

The plant discharges into the Rhine River basin, a major transboundary waterway that flows through Switzerland, France, Germany, and the Netherlands before reaching the North Sea. The Rhine supports diverse aquatic life, including migratory fish species such as salmon and eel, and its floodplains provide critical habitats. Secondary treatment reduces organic pollutants and suspended solids, helping to maintain the ecological health of this important river system.
