Overview
UNTERAMMERGAU wastewater treatment plant in Bavaria, Germany, serves 1,700 people with advanced treatment. The plant is now closed, having discharged treated water into the local watershed.
UNTERAMMERGAU is a former wastewater treatment plant located in Scherenau, Unterammergau, in the district of Garmisch-Partenkirchen, Bavaria, Germany. It served a population of approximately 1,700 residents in this Alpine community. The plant is now closed, but during its operation it provided advanced treatment for the local wastewater. As a German plant serving a small agglomeration, it operated under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for communities of this size. The plant had a designed capacity of 3,000 cubic meters per day and discharged an average volume of 430 cubic meters per day, indicating it operated well below capacity. The plant's treated effluent was discharged into the local watershed, which ultimately drains into the Ammer River, a tributary of the Amper and then the Isar, flowing into the Danube River and eventually the Black Sea. The surrounding area is ecologically sensitive, supporting diverse aquatic life in the Alpine foothills.
Environmental context
The plant discharged into the Ammer River system, part of the Danube basin that flows into the Black Sea. The local watershed includes sensitive Alpine streams that support trout and other cold-water species. Downstream, the Ammer joins the Amper and Isar rivers, which are important for regional biodiversity and water quality.
