Wang Wastewater Treatment Plant, Volkmannsdorf, Bavaria, Germany

Wang wastewater treatment plant is located in Volkmannsdorf, a district of Wang in the district of Freising, Bavaria, Germany. The plant served a population of 1,312 and had a designed capacity of 2,000 cubic meters per day, with an average discharge volume of 332 cubic meters per day. It is now closed. The plant provided advanced treatment, which goes beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive water bodies. The treated effluent from the plant would have discharged into a local watercourse within the Danube river basin, ultimately flowing into the Black Sea. The plant's operation helped protect the local aquatic environment and downstream ecosystems.

The plant is located inland in Bavaria, within the Danube river basin. The receiving water body is likely a small stream or river that flows into the Isar or Amper rivers, which are tributaries of the Danube. The Danube eventually reaches the Black Sea. The region supports diverse aquatic life and the plant's advanced treatment helped minimize nutrient pollution, protecting downstream water quality.
