Overview
Arnsberg Neheim wastewater treatment plant serves Höingen, Nordrhein-Westfalen, Germany, with a population equivalent of 108,545. The plant operates under the EU Urban Waste Water Treatment Directive.
The Arnsberg Neheim wastewater treatment plant is located in Höingen, a district of Ense in the Soest district of Nordrhein-Westfalen, Germany. It serves a population equivalent of 108,545, classifying it as a large agglomeration under EU regulations. The plant is situated near the A 445 motorway and lies inland, approximately 50 km from the coast. As a large agglomeration in Germany, the plant is required to meet stringent treatment standards under the EU Urban Waste Water Treatment Directive (91/271/EEC). This directive mandates secondary treatment as a minimum, with tertiary treatment required for discharges into sensitive areas. The plant's treatment processes and capacity details are not publicly available, but it is expected to comply with German water quality standards enforced by the relevant state authority. The treated effluent from the plant likely discharges into a local watercourse that flows into the Ruhr River, a major tributary of the Rhine. The Rhine basin is a densely populated and industrialized region, making effective wastewater treatment critical for protecting downstream ecosystems and drinking water supplies. The plant plays a key role in maintaining water quality in this important European watershed.
Environmental context
The plant's receiving water body is likely a small stream or river in the Ruhr catchment, which flows into the Rhine River and ultimately the North Sea. The Rhine basin supports diverse aquatic life and is a vital corridor for migratory fish. Effective treatment is essential to prevent nutrient pollution and protect downstream ecosystems, including the Rhine delta and coastal waters.

As a German plant serving over 100,000 people, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment and potentially tertiary treatment if discharging into sensitive areas.
For large agglomerations (>100,000 PE) in Germany, secondary treatment is mandatory, and tertiary treatment (nutrient removal) is often required, especially in sensitive catchments like the Rhine basin.
