Teunz OT Fuchsberg Wastewater Treatment Plant, Bavaria, Germany

Teunz OT Fuchsberg is a former wastewater treatment plant located in the Kühried area of Teunz, a municipality in the Schwandorf district of Bavaria, Germany. The plant was designed to serve a small population of 1,291 people, reflecting its role in a rural community. It is currently closed and no longer in operation. The plant provided secondary treatment, which is the standard biological treatment stage required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The directive mandates secondary treatment for all discharges from agglomerations with a population equivalent (PE) between 2,000 and 10,000, and Teunz OT Fuchsberg, serving 1,291 people, falls below this threshold, indicating that it likely operated under national German regulations for smaller communities. The treated effluent from the plant would have been discharged into local watercourses that drain into the Naab River, a tributary of the Danube. The Danube ultimately flows into the Black Sea, making this plant part of a vast transboundary river basin. The surrounding region is characterized by forests and agricultural land, and the local watershed supports diverse aquatic life.

The plant's discharge would have entered small streams in the Kühried area, which flow into the Schwarzach River, a tributary of the Naab. The Naab joins the Danube near Regensburg, and the Danube carries water through several countries to the Black Sea. This watershed supports a variety of fish species and provides habitat for migratory birds. The region is not coastal, so marine discharge is not a concern.
