Konigsberg_Bay Wastewater Treatment Plant, Unfinden, Bayern

Konigsberg_Bay is a wastewater treatment plant located in Unfinden, a district of Königsberg in Bayern, Germany. The plant served a population of 1,890 and had a designed capacity of 4,200 m³/day, with a discharge volume of 969.24 m³/day. It is currently closed. As a secondary treatment plant, it provided biological treatment to remove organic matter and suspended solids. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), plants serving agglomerations of this size (under 2,000 population equivalent) are typically required to provide appropriate treatment, though secondary treatment is common for smaller communities in Germany. The facility is located inland in the Haßberge district of Bavaria. The region drains into the Main River system, which flows into the Rhine and ultimately the North Sea.

The plant is situated in the Haßberge district of Bavaria, an inland region with a temperate climate. The local watershed drains toward the Main River, a major tributary of the Rhine. The Rhine basin supports diverse aquatic life and is an important ecological corridor in Europe. The plant's closure likely reduces local discharge impacts, but historical operations would have affected nearby streams that feed into the Main system.
