Haltern Hullern Wastewater Treatment Plant | Haltern am See, Germany

Haltern Hullern is a wastewater treatment plant located in the Hullern district of Haltern am See, in the state of Nordrhein-Westfalen, Germany. The plant serves a population of approximately 2,159 residents, classifying it as a small agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients such as nitrogen and phosphorus. It has a designed capacity of 2,500 cubic meters per day and currently discharges a volume of 546.39 cubic meters per day. As a German facility, it operates under the national implementation of the EU UWWTD, which mandates appropriate treatment levels based on the sensitivity of receiving waters. The treated effluent is discharged into the local watershed, which ultimately drains into the Lippe River and then the Rhine River. The Rhine basin is a major European waterway supporting diverse aquatic life and providing drinking water for millions. The plant's advanced treatment helps protect this ecologically important river system from nutrient pollution.

The plant discharges into the Lippe River, a tributary of the Rhine River. The Rhine basin is a densely populated and industrialized region, but also supports important fish species such as salmon and eel. Advanced treatment at this plant helps reduce nutrient loads, protecting downstream water quality in the Rhine Delta and the North Sea.
