Ehekirchen Wastewater Treatment Plant, Wallertshofen, Bavaria

The Ehekirchen wastewater treatment plant is located in Wallertshofen, a district of Ehekirchen in the Bavarian district of Neuburg-Schrobenhausen, Germany. This facility serves a population of approximately 2,734 residents and operates with a designed capacity of 3,500 cubic meters per day, currently discharging an average of 632.12 cubic meters per day. As a secondary treatment plant, it provides biological treatment to remove organic matter and suspended solids. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), plants serving agglomerations between 2,000 and 10,000 population equivalents are required to have secondary treatment, which this facility meets. The plant is part of Germany's well-regulated wastewater infrastructure, overseen by state authorities in Bavaria. The treated effluent is discharged into local watercourses that ultimately drain into the Danube River basin. The Danube flows eastward through Central and Eastern Europe before reaching the Black Sea. This region's aquatic ecosystems benefit from the plant's pollution control, supporting biodiversity in streams and rivers that feed into the Danube.

The plant discharges into local streams that are part of the Danube River basin, one of Europe's major watersheds. The Danube flows through multiple countries before emptying into the Black Sea, supporting diverse aquatic life including fish species such as sturgeon and migratory birds. The secondary treatment provided by this plant helps reduce nutrient and organic pollution, protecting downstream water quality in ecologically sensitive areas.
