Ostringen KLA Odenheim Wastewater Treatment Plant, Östringen, Baden-Württemberg

Ostringen KLA Odenheim is a municipal wastewater treatment plant located in the Odenheim district of Östringen, in the state of Baden-Württemberg, Germany. The plant serves a population of approximately 6,600 residents, placing it in the small agglomeration category under EU regulations. As a German facility, the plant is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The plant's treatment process and capacity are designed to meet these standards, ensuring compliance with national water quality objectives. The treated effluent is discharged into local waterways that ultimately drain into the Rhine River basin, a major European watershed. The Rhine supports diverse aquatic ecosystems and provides drinking water for millions. The plant plays a key role in protecting downstream water quality in this ecologically significant region.

The plant discharges into the Rhine River basin, which flows through Germany and the Netherlands into the North Sea. The Rhine supports diverse aquatic life, including migratory fish species, and its water quality is critical for both ecological health and human use. The plant's treatment helps reduce nutrient and pollutant loads in this sensitive watershed.
