Kreuzwertheim Wastewater Treatment Plant, Bavaria, Germany

The Kreuzwertheim wastewater treatment plant is located in the town of Kreuzwertheim, in the Main-Spessart district of Bavaria, Germany. The facility serves a population of approximately 6,212 residents, classifying it as a small to medium agglomeration under EU regulations. As a German wastewater treatment plant, it operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations of this size. The plant's treatment processes and capacity are designed to meet national standards set by the German Water Resources Act (Wasserhaushaltsgesetz). The plant discharges treated effluent into the local water system, which ultimately drains into the Main River, a major tributary of the Rhine. The Rhine basin is a critical ecological corridor in Europe, supporting diverse aquatic life and providing water for millions of people. The plant's operation helps protect the water quality of the Main and Rhine rivers.

The Kreuzwertheim plant discharges into the local watershed that feeds the Main River, which flows into the Rhine River and eventually the North Sea. The Main River supports diverse fish species and is an important migratory route for aquatic life. The plant's treatment helps maintain water quality in this ecologically sensitive river system.
