Buttelborn Wastewater Treatment Plant, Büttelborn, Hessen, Germany

The Buttelborn wastewater treatment plant is located in Büttelborn, a municipality in the Kreis Groß-Gerau district of Hessen, Germany. The plant serves a population of approximately 16,092, classifying it as a medium-sized agglomeration under EU regulations. Its location near the B 44 road provides access for maintenance and operations. 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 with a population equivalent (PE) between 10,000 and 150,000. The plant's treatment processes are designed to meet these standards, ensuring compliance with national and EU water quality objectives. The regulatory framework also mandates regular monitoring and reporting to the relevant authorities. The treated effluent from the Buttelborn plant is discharged 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 plays a crucial role in protecting the water quality of the Rhine catchment area, particularly in the densely populated and agriculturally active region of Hessen.

The Buttelborn plant discharges into the local drainage network that flows into the Rhine River, one of Europe's most important waterways. The Rhine basin supports a wide range of aquatic life, including fish species such as salmon and eel, and is a vital corridor for migratory birds. The plant's operations help maintain water quality in this ecologically sensitive region, which is also used for agriculture, recreation, and drinking water supply downstream.
