Overview
Heldenstein wastewater treatment plant in Weidenbach, Bavaria, Germany, serves 1,250 people with secondary treatment. The plant is closed and discharges 930 m³/day.
Heldenstein is a former wastewater treatment plant located in Weidenbach, Bavaria, Germany. It served a small population of 1,250 people and was designed with a capacity of 4,999 m³/day, though actual discharge volume was 930 m³/day. The plant is now closed. The plant provided secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. For populations under 2,000, the directive allows appropriate treatment, and secondary treatment meets this requirement. The plant's treated effluent was discharged into local waterways within the Inn River basin, which flows into the Danube and ultimately the Black Sea. The region supports diverse aquatic life and contributes to the ecological health of the Danube watershed.
Environmental context
The plant discharged into the Inn River basin, part of the Danube watershed that drains into the Black Sea. The local environment supports aquatic ecosystems and migratory fish species. The plant's closure reduces local nutrient loading, benefiting downstream water quality.
