Neureichenau Wastewater Treatment Plant, Kernberg, Bavaria, Germany

The Neureichenau wastewater treatment plant is located in Kernberg, a district of Neureichenau in the Bavarian region of Germany. It serves a population of around 2,724 people, classifying it as a small agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). The plant is situated in the rural landscape of the Bavarian Forest near the border with Austria and the Czech Republic. The plant provides secondary treatment, which is the minimum standard required by the EU UWWTD for freshwater discharges from agglomerations of this size. With a designed capacity of 6,000 m³/day and an average daily flow of 811.17 m³/day, the facility operates well below its capacity, indicating potential for future growth or seasonal variations. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into local watercourses that drain into the Danube River basin. The plant plays a key role in protecting the water quality of the region's streams and rivers, which ultimately flow into the Black Sea. The surrounding area is ecologically sensitive, supporting diverse aquatic life and contributing to the overall health of the Danube watershed.

The Neureichenau plant discharges into small streams within the Danube River basin, which flows through multiple countries before reaching the Black Sea. The local watershed is part of the Bavarian Forest, a region known for its forested hills and cold-water streams that support trout and other sensitive species. The plant's secondary treatment helps reduce nutrient and organic pollution, safeguarding downstream aquatic habitats and the ecological integrity of the Danube delta.
