The Velburg wastewater treatment plant is located in Hollerstetten, a district of Velburg in the Bavarian region of Germany. The facility serves a population of around 5,182, classifying it as a small to medium agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). As a German plant operating under the EU UWWTD, it is required to provide secondary treatment as a minimum standard. For agglomerations of this size, the directive mandates appropriate treatment to protect receiving waters. The plant's specific treatment processes and capacity details are not publicly available, but it adheres to national regulations implementing the directive. The treated effluent is discharged into local water bodies that eventually drain into the Danube River basin, which flows into the Black Sea. The plant plays a role in protecting the regional aquatic environment, including streams and rivers that support diverse freshwater ecosystems.

The plant discharges into local streams that are part of the Danube River basin. The Danube flows southeast through several countries before reaching the Black Sea. This watershed supports a variety of aquatic life and is an important ecological corridor. The treatment plant helps reduce nutrient and pollutant loads, contributing to the health of downstream water bodies.
