Greding Wastewater Treatment Plant, Greding, Bavaria, Germany

The Greding wastewater treatment plant is located in the town of Greding, in the Bavarian district of Roth, Germany. It serves a population of approximately 6,400 residents, classifying it as a small to medium agglomeration under EU regulations. The plant is situated near the Mettendorf area, along state road St 2227. As a German facility, the plant is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations with a population equivalent (PE) between 2,000 and 10,000. For plants serving around 6,400 people, secondary treatment is the standard, ensuring effective removal of organic matter and suspended solids. The plant's discharge is regulated under Germany's national water laws, which implement the directive's requirements. The treated effluent from the Greding plant is discharged into a local water body that ultimately drains into the Danube River basin. The Danube is one of Europe's major rivers, flowing through multiple countries before reaching the Black Sea. The plant plays a key role in protecting the local watershed and downstream ecosystems, including the Danube's diverse aquatic habitats and the ecologically sensitive Danube Delta.

The Greding plant discharges into a local stream that is part of the Danube River basin. The Danube flows eastward through several countries before emptying into the Black Sea. The downstream environment includes ecologically important floodplains and wetlands that support diverse aquatic life and migratory bird species. The plant's treatment helps maintain water quality in this transboundary river system.
