Hohenthann Wastewater Treatment Plant, Bavaria | Germany

Hohenthann wastewater treatment plant is located in the municipality of Hohenthann in the Landkreis Landshut district of Bavaria, Germany. The plant serves a population of approximately 5,593 and is designed to handle a capacity of 8,000 m³ per day, with an average discharge volume of 901.43 m³ per day. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), advanced treatment is required for discharges into sensitive areas, and Germany has designated many water bodies as sensitive, particularly in the Danube and Rhine basins. The treated effluent from Hohenthann is discharged into local watercourses that eventually drain into the Danube River basin. The Danube flows southeast through Europe into the Black Sea, supporting diverse aquatic ecosystems along its course. The plant's advanced treatment helps protect downstream water quality in this ecologically significant river system.

Hohenthann lies within the Danube River basin, one of Europe's major watersheds. The treated wastewater from the plant enters local streams that feed into the Danube, which ultimately flows into the Black Sea. The Danube supports a rich diversity of fish and bird species, including several migratory fish like sturgeon. Advanced treatment at the plant reduces nutrient loads, helping to prevent eutrophication in downstream lakes and the Black Sea coastal zone.
