Overview
Bad Kohlgrub wastewater treatment plant serves approximately 6,200 people in Bavaria, Germany. It operates under the EU Urban Waste Water Treatment Directive, which mandates secondary treatment for agglomerations of this size.
The Bad Kohlgrub wastewater treatment plant is located in the municipality of Bad Kohlgrub in the Bavarian district of Garmisch-Partenkirchen, Germany. The plant serves a population of around 6,200 residents, placing it in the small-to-medium agglomeration category under EU regulations. As a German facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations with a population equivalent between 2,000 and 10,000. German implementation through the Abwasserverordnung (Wastewater Ordinance) sets strict effluent standards for organic matter, nutrients, and other pollutants. The treated effluent is discharged into local watercourses that ultimately drain into the Ammer River, a tributary of the Isar, which flows into the Danube and then the Black Sea. The plant plays a key role in protecting the sensitive Alpine foothill ecosystems and groundwater resources in the region.
Environmental context
The plant discharges into the catchment of the Ammer River, which flows through the Alpine foothills before joining the Isar River. The Isar is a major tributary of the Danube, which empties into the Black Sea. This watershed supports diverse aquatic life and provides drinking water for downstream communities. The region's karst geology makes groundwater particularly vulnerable to contamination, emphasizing the need for effective wastewater treatment.
