Dremmen 1 Wastewater Treatment Plant, Heinsberg, Nordrhein-Westfalen

Dremmen 1 is a municipal wastewater treatment plant located in the Dremmen district of Heinsberg, in the state of Nordrhein-Westfalen, Germany. The plant serves a population of around 9,939, placing it in the small-to-medium agglomeration category under EU classification. As a German facility, Dremmen 1 is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The plant's treatment processes and capacity are managed to meet national water quality standards set by the German Water Resources Act (Wasserhaushaltsgesetz). The treated effluent from Dremmen 1 is discharged into the local water system, which ultimately drains into the Rur River basin. The Rur flows through the region and joins the Meuse River in the Netherlands, eventually reaching the North Sea. The plant plays a key role in protecting the water quality of the Rur catchment area.

Dremmen 1 discharges into the Rur River basin, a tributary of the Meuse River, which flows into the North Sea. The Rur catchment supports diverse aquatic life and is used for recreation and agriculture. The plant's operations help maintain water quality in this ecologically sensitive river system, which is part of the larger Rhine-Meuse delta.
