Bordelum Wastewater Treatment Plant, West-Bordelum, Schleswig-Holstein

Bordelum wastewater treatment plant is located in West-Bordelum, a locality in the municipality of Bordelum, within the district of Nordfriesland, Schleswig-Holstein, Germany. The plant served a population of 1,875 and was designed with a capacity of 2,000 m³ per day, with an average discharge volume of 474.52 m³ per day. The facility provided advanced treatment, reflecting high environmental standards typical of German wastewater infrastructure. The plant operated under Germany's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for agglomerations of this size. Although the plant is now closed, its advanced treatment level indicates compliance with stringent effluent quality standards, particularly relevant given its coastal proximity. The plant's treated effluent likely discharged into local watercourses draining to the North Sea. The region's coastal ecology, including the Wadden Sea, is ecologically sensitive and supports diverse marine life. The plant's closure may reflect consolidation of wastewater services in the area.

Bordelum is located near the North Sea coast in Schleswig-Holstein, within the drainage basin of the North Sea. The local watershed includes small streams and ditches that flow into the Wadden Sea, a shallow tidal area of high ecological importance. The Wadden Sea supports migratory birds, seals, and diverse benthic communities. The plant's advanced treatment helped protect this sensitive coastal environment from nutrient and pollutant loads.
