Overview
Kochel_See wastewater treatment plant serves Kochel am See, Bavaria, Germany, treating wastewater for approximately 10,700 residents. The plant discharges into the local watershed, ultimately draining into the Isar River and the Danube basin.
Kochel_See is a municipal wastewater treatment plant located in Kochel am See, a town in the Bavarian district of Bad Tölz-Wolfratshausen, Germany. The plant serves a population of approximately 10,700 people, placing it in the medium agglomeration category under EU regulations. It is situated near the Kochelsee lake, a popular recreational area in the Bavarian Alps. As a German plant serving a population between 2,000 and 15,000, it is subject to the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment as a minimum. It operates under Germany's national water management framework, which mandates stringent effluent standards for sensitive areas like the Alpine foothills. The treated effluent from Kochel_See is discharged into the local receiving waters, which flow into the Loisach River and eventually the Isar River, a major tributary of the Danube. The Danube carries the water through Central Europe to the Black Sea. The plant plays a key role in protecting the Kochelsee lake and downstream aquatic ecosystems from nutrient pollution and pathogens.
Environmental context
The plant's discharge enters the local watershed, which drains into the Loisach River and then the Isar River, a major tributary of the Danube River system. The Danube ultimately flows into the Black Sea. The Kochelsee lake and surrounding wetlands are ecologically sensitive, supporting diverse aquatic life and serving as a habitat for migratory birds. The region's Alpine terrain and tourism activity make nutrient management critical to prevent eutrophication in the lake.
