Eppishausen Wastewater Treatment Plant, Aspach, Bavaria, Germany

The Eppishausen wastewater treatment plant is located in Aspach, a district of Eppishausen in the Bavarian region of Unterallgäu, Germany. Designed to serve a population of 1,270, the plant provided secondary treatment before its closure. The facility had a designed capacity of 1,800 m³/day and discharged an average volume of 321.41 m³/day. As a secondary treatment plant in Germany, Eppishausen operated under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The plant's closure may reflect consolidation of wastewater services in the region, as smaller plants are often replaced by larger, more efficient facilities. The treated effluent from the plant was discharged into local watercourses that drain into the Danube River basin, ultimately reaching the Black Sea. The plant's operation helped protect the local aquatic environment by reducing organic load and nutrients in the receiving waters.

The plant discharged into small streams in the Danube River basin, which flows through Bavaria and several other European countries before reaching the Black Sea. The local watershed supports diverse aquatic life and is part of a larger ecological network. The plant's secondary treatment helped control nutrient pollution, which is important for preventing eutrophication in downstream water bodies.
