Overview
Pellworm wastewater treatment plant in Schleswig-Holstein, Germany, served 845 people with secondary treatment before closure. The plant discharged 213.85 m³/day into the North Sea coastal environment.
The Pellworm wastewater treatment plant is located on the island of Pellworm in the North Frisian region of Schleswig-Holstein, Germany. It served a small population of 845 residents and is now closed. The plant was situated in a coastal area, less than 10 km from the North Sea. As a secondary treatment facility, the plant provided biological treatment to reduce organic matter and suspended solids. The designed capacity was 2770 m³/day, with an actual discharge volume of 213.85 m³/day. Under the EU Urban Waste Water Treatment Directive, small agglomerations like Pellworm are typically required to have appropriate treatment, and secondary treatment meets that standard for coastal discharge. The treated effluent was discharged into the North Sea, which is a sensitive marine environment. The Wadden Sea, a UNESCO World Heritage site, lies nearby and is ecologically significant for migratory birds and marine life.
Environmental context
The plant discharged into the North Sea, which receives waters from the surrounding North Frisian Wadden Sea. This area is a critical habitat for seals, migratory birds, and diverse benthic communities. The Wadden Sea ecosystem is highly productive and sensitive to nutrient inputs, making proper wastewater treatment essential for maintaining water quality and ecological balance.
