ZV Schlierachtal Sitz Miesbach Wastewater Treatment Plant, Miesbach, Bavaria

ZV Schlierachtal Sitz Miesbach is a wastewater treatment plant located in Miesbach, in the Bavarian region of Germany. It serves a population of around 28,000, classifying it as a medium-sized agglomeration under EU regulations. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), plants serving between 10,000 and 100,000 population equivalent are required to provide secondary treatment, with tertiary treatment mandated if the receiving waters are designated as sensitive areas. It is expected to meet these standards. The plant discharges into the local watershed, which ultimately drains into the Mangfall River, a tributary of the Inn River, and then into the Danube River basin. This waterway supports diverse aquatic life and is part of a larger ecological network flowing towards the Black Sea.

The plant's treated effluent enters the Schlierach stream, which flows into the Mangfall River. The Mangfall joins the Inn River, a major tributary of the Danube, which eventually reaches the Black Sea. This watershed supports a variety of fish species and riparian habitats, and is important for regional biodiversity. The area is part of the Bavarian Alpine foothills, with sensitive ecosystems that benefit from effective wastewater treatment.
