Overview
Obernzell wastewater treatment plant serves the community of Haar in Bavaria, Austria. It is an inland facility located near the Danube River basin.
The Obernzell wastewater treatment plant is located in the municipality of Haar, within the Obernzell district of Passau, Bavaria, Austria. Serving a population of approximately 2,982, this facility is part of the region's municipal wastewater infrastructure, handling domestic sewage from the local community. As a small-scale treatment plant in Austria, it operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which mandates secondary treatment for agglomerations of this size. The plant's treatment processes are designed to meet national standards for effluent quality before discharge. The treated effluent from the Obernzell plant is discharged into local waterways that ultimately drain into the Danube River, one of Europe's major rivers. The Danube flows eastward through several countries before reaching the Black Sea, making the plant's operations important for downstream water quality and ecosystem health.
Environmental context
The Obernzell plant discharges into a tributary of the Danube River, which flows through the Bavarian landscape before joining the main Danube channel. The Danube is a critical waterway for Central and Eastern Europe, supporting diverse aquatic life and providing water for agriculture and industry. The plant's location inland, away from coastal areas, reduces direct marine impact, but its effluent contributes to the overall nutrient load in the Danube basin, which can affect the Black Sea ecosystem downstream.
