Vestenbergsgreuth Wastewater Treatment Plant, Dutendorf, Bayern

The Vestenbergsgreuth wastewater treatment plant is located in Dutendorf, a locality within the municipality of Vestenbergsgreuth in the district of Erlangen-Höchstadt, Bayern, Germany. It served a population of 1,510 people, classifying it as a small agglomeration under the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant is currently closed. As a secondary treatment facility, the plant provided biological treatment to reduce organic matter and suspended solids. For small agglomerations in Germany, secondary treatment is the standard requirement under the EU directive, ensuring compliance with effluent quality standards. The designed capacity of 5,500 cubic meters per day indicates the plant was built to handle peak flows. The plant's treated effluent was discharged into local watercourses that drain into the Regnitz river system, which flows into the Main River and ultimately into the Rhine. This catchment supports diverse aquatic life and is part of a densely populated region with agricultural and industrial activities. The closure of the plant may redirect flows to a larger regional facility.

The plant discharged into the Regnitz river basin, which flows into the Main River and then the Rhine, one of Europe's major waterways. The receiving waters support diverse aquatic ecosystems and are used for recreation and agriculture. The plant's secondary treatment helped protect downstream water quality in this sensitive watershed.
