The Hinterschmiding wastewater treatment plant is located in Sonndorf, a district of Hinterschmiding in the Bavarian county of Freyung-Grafenau, Germany. This facility serves a population of about 3,656 people, placing it in the small agglomeration category under EU classification. The plant provides secondary treatment, which is the minimum standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. With a designed capacity of 3,000 cubic meters per day and an average daily flow of approximately 857.88 thousand cubic meters per year, the plant operates within its capacity to manage municipal wastewater from the local community. The treated effluent is discharged into local watercourses that ultimately drain into the Danube River basin, contributing to the Black Sea watershed. The plant's operation helps protect the sensitive ecosystems of the Bavarian Forest region, supporting water quality in downstream rivers and maintaining ecological balance in this forested, upland area.
Environmental context
The plant discharges into small streams that feed into the Ilz River, a tributary of the Danube. The Ilz River flows through the Bavarian Forest, a region known for its diverse aquatic life and forest ecosystems. Downstream, the Danube carries the treated water to the Black Sea, making the plant's performance important for transboundary water quality. The surrounding area is characterized by low population density and forested hills, where maintaining clean water supports local biodiversity and recreational uses.
