Hiltenfingen Wastewater Treatment Plant, Bayern, Germany

Hiltenfingen wastewater treatment plant is located in the town of Hiltenfingen, in the Bavarian district of Augsburg, Germany. The plant served a population of approximately 1,933 people and was designed with a capacity of 2,000 cubic meters per day. It is now closed, but during operation it provided advanced treatment, which is typical for sensitive areas under the EU Urban Waste Water Treatment Directive. As a German plant, Hiltenfingen operated under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires advanced treatment for discharges into sensitive areas. The plant's advanced treatment level indicates it likely employed nutrient removal to protect local water bodies. The plant's discharge volume of 489.20 cubic meters per day reflects its small scale. The plant's treated effluent was discharged into local waterways that drain into the Wertach River, a tributary of the Lech, which ultimately flows into the Danube River and then the Black Sea. The plant's operation helped protect the ecological health of these water bodies, supporting aquatic life and water quality in the region.

The plant's discharge entered the local drainage network, which flows into the Wertach River, a tributary of the Lech River. The Lech joins the Danube, which empties into the Black Sea. The region's watershed supports diverse aquatic habitats, and the plant's advanced treatment helped minimize nutrient loading and protect downstream ecosystems.
