Gerolfingen Wastewater Treatment Plant, Aufkirchen, Bavaria

The Gerolfingen wastewater treatment plant is located in Aufkirchen, within the Hesselberg administrative district in the Bavarian region of Germany. It serves a population of approximately 3,120 people, classifying it as a small agglomeration under EU regulations. The plant is situated in a rural, inland area near the Wörnitz River basin. As a German facility serving fewer than 10,000 population equivalent, the plant is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment before discharge. For small agglomerations like Gerolfingen, secondary treatment is typically mandated, though specific treatment processes and capacity details are not publicly available. It operates as part of Germany's comprehensive wastewater infrastructure. The treated effluent from the plant likely discharges into local watercourses that flow into the Wörnitz River, a tributary of the Danube. The Danube ultimately drains into the Black Sea, making this plant part of a vast transboundary river basin. The surrounding region is characterized by agricultural land and small settlements, and the plant plays a key role in protecting local water quality and downstream ecosystems.

The Gerolfingen plant is situated in the Danube River basin, with treated effluent likely entering the Wörnitz River, a tributary of the Danube. The Danube flows through multiple countries before reaching the Black Sea, making water quality management critical for downstream ecosystems. The region supports diverse aquatic life, including fish species such as Danube salmon and various migratory birds. The plant's operations help prevent nutrient pollution that could contribute to eutrophication in downstream lakes and coastal areas of the Black Sea.
