Wallersdorf Wastewater Treatment Plant, Moosfürth, Bavaria

Wallersdorf wastewater treatment plant is located in the Moosfürth district of Wallersdorf, in the Landkreis Dingolfing-Landau region of Bavaria, Germany. The plant serves a population equivalent of 6,352, classifying it as a small to medium agglomeration under EU regulations. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), plants serving between 2,000 and 10,000 population equivalents are required to provide secondary treatment. It is expected to meet this standard. The plant is part of Germany's extensive wastewater infrastructure, which is regulated by the Federal Water Act (Wasserhaushaltsgesetz) and state-level authorities. The treated effluent from the plant is discharged into local watercourses that ultimately drain into the Danube River basin. The Danube flows through several countries before reaching the Black Sea, making the plant's operations important for downstream water quality in this major European watershed.

The plant's discharge contributes to the Danube River basin, a major European watershed that drains into the Black Sea. The Danube supports diverse aquatic ecosystems and is an important migratory corridor for fish species such as sturgeon. The region's water quality is managed under the EU Water Framework Directive, which aims to achieve good ecological status for all water bodies.
