KA Neuenhaus Wastewater Treatment Plant, Neuenhaus, Lower Saxony

KA Neuenhaus is a municipal wastewater treatment plant located in Veldhausen, near Neuenhaus, in the district of Grafschaft Bentheim, Lower Saxony, Germany. The plant serves a population of around 13,707, classifying it as a medium-sized agglomeration under EU regulations. As a German plant serving over 10,000 people, KA Neuenhaus is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment as a minimum. For inland plants in sensitive areas, more stringent treatment may be mandated. Compliance with the directive ensures appropriate treatment levels. The treated effluent is discharged into local watercourses that flow into the Vechte River, which eventually drains into the Zwarte Water and the IJsselmeer in the Netherlands. This downstream pathway supports diverse aquatic life and is important for regional water quality management.

The plant discharges into the Vechte River basin, which flows westward into the Netherlands, joining the Zwarte Water and eventually the IJsselmeer, a large freshwater lake. This watershed supports diverse aquatic habitats and is used for recreation and agriculture. The plant's operations help protect downstream water quality in this transboundary river system.
