Adlkofen Wastewater Treatment Plant, Blumberg, Bayern, Germany

The Adlkofen wastewater treatment plant is located in the Blumberg district of Adlkofen, within the Landkreis Landshut in Bayern, Germany. It served a population of approximately 1,751 people before its operational status was listed as closed. The facility was designed with a capacity of 3,000 m³ per day and treated an average discharge volume of 443.14 m³ per day. The plant employed advanced treatment processes, reflecting Germany's commitment to high water quality standards under the EU Urban Waste Water Treatment Directive (91/271/EEC). For small agglomerations like Adlkofen, advanced treatment is often implemented to protect sensitive receiving waters, even though secondary treatment is the minimum requirement for populations under 10,000. The treated effluent from Adlkofen likely discharged into a local watercourse within the Danube basin, as the region drains toward the Danube River. The Danube and its tributaries support diverse aquatic ecosystems and are important for drinking water supply and recreation downstream.

The Adlkofen plant is situated inland in the Isar-Inn region of Bavaria, part of the Danube River basin. The nearest major river is the Isar, a tributary of the Danube. The Danube flows into the Black Sea, supporting a vast watershed that includes ecologically sensitive areas such as the Danube Delta. The local watershed provides habitat for fish species like the Danube salmon and supports migratory birds. Advanced treatment at this plant helped protect downstream water quality.
