Saaldorf OT Surheim Wastewater Treatment Plant, Surheim, Bavaria

Saaldorf OT Surheim is a former wastewater treatment plant located in Surheim, a district of Saaldorf-Surheim in the Bavarian region of Germany. The plant served a population of approximately 1,602 people and had a designed capacity of 3,500 cubic meters per day, with a recorded discharge volume of 405.43 cubic meters. It provided secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive for smaller agglomerations. As a German plant, it operated under the national implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for all agglomerations above 2,000 population equivalent discharging into freshwater. Although the plant is now closed, its historical role was to treat domestic wastewater from the local community before discharge into the surrounding environment. Given its inland location in Bavaria, treated effluent likely discharged into a local stream or river that feeds into the Danube basin. The region is characterized by alpine foothills and agricultural land, and the plant's operation would have helped protect local water quality and downstream ecosystems.

The plant is located in the Bavarian region of Germany, near the border with Austria. The area drains into the Salzach River, a tributary of the Inn River, which flows into the Danube and ultimately the Black Sea. The local watershed supports diverse aquatic life and is part of a sensitive alpine ecosystem. Proper wastewater treatment is essential to prevent nutrient enrichment and protect downstream habitats.
