VG GRABEN NEUDORF KLA Dettenheim Wastewater Treatment Plant, Liedolsheim, Germany

VG GRABEN NEUDORF KLA Dettenheim is a wastewater treatment plant located in Liedolsheim, a district of Dettenheim in the Karlsruhe district of Baden-Württemberg, Germany. The plant serves a population of approximately 22,350, classifying it as a medium-sized agglomeration under EU regulations. As a German plant, it operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations of this size. The regulatory framework ensures compliance with national and EU standards for effluent quality. The plant discharges treated wastewater into local water bodies 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 operations contribute to protecting the Rhine's water quality and the ecological health of its tributaries.

The plant's treated effluent flows into the Rhine River basin, which drains into the North Sea. The Rhine supports a wide range of aquatic life, including migratory fish species such as salmon and eel. The plant's location in the Upper Rhine Plain means its discharge affects a region known for groundwater recharge and floodplain ecology. Protecting water quality here is critical for downstream ecosystems and drinking water supplies.
