Weichering Wastewater Treatment Plant, Osterfeldsiedlung, Bavaria (Closed)

The Weichering wastewater treatment plant is located in Osterfeldsiedlung, a locality within the municipality of Weichering in the district of Neuburg-Schrobenhausen, Bavaria, Germany. It served a population of approximately 1,563 people and is now closed. The plant provided secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive for smaller agglomerations. The plant had a designed capacity of 2,800 cubic meters per day, with an average discharge volume of 491.54 cubic meters per day. As a closed facility, it no longer processes wastewater, and the local population is likely served by other regional treatment infrastructure. The area drains into the Danube River basin, which flows into the Black Sea. The plant's closure may reflect consolidation of wastewater services in the region.

The plant is located inland in Bavaria, over 50 km from the coast. The local watershed is part of the Danube River basin, which ultimately drains into the Black Sea. The Danube and its tributaries support diverse aquatic life and are ecologically sensitive, particularly for migratory fish species. The closure of this plant may reduce local discharge impacts, but the historical effluent from secondary treatment would have contributed nutrients and organic matter to the receiving waters.
