Ammerseewerke gKU Wastewater Treatment Plant, Eching am Ammersee, Bavaria

Ammerseewerke gKU is a municipal wastewater treatment plant located in Eching am Ammersee, in the Bavarian district of Landsberg am Lech, Germany. The plant serves a population of around 94,000, classifying it as a large agglomeration under EU regulations. Its location near the Ammersee lake places it in a sensitive freshwater environment. As a German plant serving over 10,000 population equivalent, Ammerseewerke gKU is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires tertiary treatment for discharges into sensitive areas like lakes. The plant's treatment processes are designed to meet stringent nutrient removal standards to protect the Ammersee and its downstream waters. Treated effluent from the plant is discharged into the Ammersee, a large lake in Bavaria. The Ammersee drains via the Amper River into the Isar, which ultimately flows into the Danube and then the Black Sea. The plant plays a critical role in preventing eutrophication and maintaining water quality in this ecologically sensitive lake system, which supports diverse aquatic life and recreational activities.

The Ammersee is a large, deep lake in Bavaria, part of the Danube basin. It drains via the Amper River into the Isar, which joins the Danube and flows to the Black Sea. The lake is ecologically sensitive, supporting diverse aquatic life and serving as an important habitat for fish and waterbirds. Nutrient inputs from wastewater must be carefully managed to prevent algal blooms and maintain water quality.
