Dentlein_Forst Wastewater Treatment Plant, Schwaighausen, Bavaria

The Dentlein_Forst wastewater treatment plant is located in Schwaighausen, a locality within Dentlein am Forst in the Ansbach district of Bavaria, Germany. Designed to serve a population of 1,650, the plant provided advanced treatment for municipal wastewater. Although the plant is now closed, it was part of the region's wastewater infrastructure. The plant had a designed capacity of 3,000 cubic meters per day and discharged an average volume of 417.58 cubic meters per day. As a German facility, it operated under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment levels based on the size of the agglomeration and the sensitivity of receiving waters. Advanced treatment is typically mandated for discharges into sensitive areas to reduce nutrient loads. The treated effluent from the plant would have been discharged into local watercourses that drain into the Danube River basin, ultimately reaching the Black Sea. The region is characterized by agricultural land and small settlements, making the protection of surface water quality important for both ecological health and downstream uses.

The plant's discharge likely entered small streams in the Wörnitz River system, a tributary of the Danube. The Danube flows through multiple countries before reaching the Black Sea, making nutrient management critical for preventing eutrophication in the Black Sea's northwestern shelf. The local watershed supports diverse aquatic life and is part of a broader network of rivers and wetlands that provide habitat for fish and migratory birds.
