Nebel Wastewater Treatment Plant, Schleswig-Holstein, Germany

The Nebel wastewater treatment plant is located in the municipality of Nebel on the island of Föhr, part of the Schleswig-Holstein region in northern Germany. The plant serves a population of approximately 6,600 residents and is situated in a coastal environment near the North Sea. The facility employs advanced treatment processes, meeting the stringent requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC). With a designed capacity of 9,950 m³/day and an average daily discharge of 678 m³, the plant operates well below its capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into the North Sea via local waterways. As a coastal plant, it plays a critical role in protecting the sensitive marine ecosystem of the Wadden Sea, a UNESCO World Heritage site known for its tidal flats and biodiversity. The advanced treatment ensures minimal nutrient and pollutant loading to the receiving waters.

The plant discharges into the North Sea, which is part of the Wadden Sea ecosystem, an ecologically sensitive area supporting diverse marine life, including seals, migratory birds, and fish. The advanced treatment helps maintain water quality in this coastal region, reducing eutrophication risks and protecting habitats.
