Overview
ZV Starnberger See Sitz Starnberg is a wastewater treatment plant in Starnberg, Bavaria, Germany, serving approximately 70,000 people. It operates under the EU Urban Waste Water Treatment Directive.
ZV Starnberger See Sitz Starnberg is a wastewater treatment plant located in Starnberg, Bavaria, Germany. The plant serves a population of around 70,000, classifying it as a medium to large agglomeration under EU regulations. It is situated near the Starnberger See, a large lake in the Bavarian Alpine foothills. As a German plant serving over 10,000 population equivalent, it is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment as a minimum. For discharges into sensitive areas like lakes, more stringent treatment (tertiary) may be mandated to prevent eutrophication. The regulatory framework ensures appropriate standards. The plant's treated effluent is discharged into the Starnberger See, a lake that drains via the Würm River into the Amper and then the Isar, ultimately reaching the Danube River and the Black Sea. The lake is an ecologically sensitive water body supporting diverse aquatic life and recreational uses, making nutrient removal critical.
Environmental context
The plant discharges into Starnberger See, a deep glacial lake in Bavaria. The lake's outflow, the Würm River, flows into the Amper and then the Isar, which joins the Danube and empties into the Black Sea. Starnberger See is a mesotrophic to oligotrophic lake, sensitive to nutrient inputs that could cause algal blooms. Protecting its water quality is essential for local biodiversity and tourism.
