Petershausen Wastewater Treatment Plant: Serving Petershausen, Bavaria, Germany

Petershausen wastewater treatment plant is located in the municipality of Petershausen, in the district of Dachau, Bavaria, Germany. The facility serves a population of approximately 6,635 residents, classifying it as a small agglomeration under EU regulations. As a German wastewater treatment plant, Petershausen operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for all agglomerations above 2,000 population equivalent. For smaller agglomerations like Petershausen, appropriate treatment must ensure the receiving water body's environmental quality is not compromised. The treated effluent from the plant is discharged into local watercourses that ultimately drain into the Danube River basin. The Danube flows through several countries before reaching the Black Sea, making the plant's operations part of a transboundary water management framework that protects downstream ecosystems and biodiversity.

The plant's discharge enters local streams that feed into the Danube River basin. The Danube is one of Europe's most important waterways, supporting diverse aquatic life and serving as a major migratory corridor for fish species. The watershed includes ecologically sensitive floodplain areas that rely on good water quality for habitat preservation. Proper treatment at Petershausen helps maintain the ecological balance of these downstream environments.
