Trappenkamp Wastewater Treatment Plant, Daldorf, Schleswig-Holstein, Germany

Trappenkamp wastewater treatment plant is located in Daldorf, within the municipality of Boostedt-Rickling in Kreis Segeberg, Schleswig-Holstein, Germany. The plant serves a population of approximately 5,000 and operates with advanced treatment technology, reflecting Germany's commitment to high water quality standards. The plant has a designed capacity of 14,000 m³/day and currently discharges 879.09 m³/day of treated wastewater. As a German facility, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates advanced treatment for sensitive areas. The plant's advanced treatment level ensures effective removal of nutrients and pollutants. The treated effluent is discharged into local watercourses that eventually drain into the Baltic Sea via the Schwentine River system. This region supports diverse aquatic life and is part of the broader Baltic Sea catchment, which is ecologically sensitive to nutrient inputs. The plant's advanced treatment helps protect downstream water quality and marine ecosystems.

The plant's discharge flows into small streams that feed into the Schwentine River, which ultimately reaches the Baltic Sea. The Baltic Sea is a semi-enclosed brackish sea with limited water exchange, making it vulnerable to eutrophication from nutrient pollution. Advanced treatment at this plant reduces nitrogen and phosphorus loads, supporting the ecological health of the downstream riverine and marine environments.
