Meldorf Wastewater Treatment Plant, Wolmersdorf, Schleswig-Holstein, Germany

The Meldorf wastewater treatment plant is located in Wolmersdorf, a district of Meldorf in the state of Schleswig-Holstein, Germany. It serves a population of about 25,350 people, classifying it as a medium-sized agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). The plant's designed capacity is 1.00 m³/s, indicating its scale for handling municipal wastewater. As a German facility, the plant operates under the EU UWWTD 91/271/EEC, which requires secondary treatment for agglomerations of this size. The directive also mandates tertiary treatment if the receiving waters are designated as sensitive areas. Compliance with national and EU standards is expected. The plant discharges treated effluent into local water bodies that eventually drain into the North Sea via the Elbe River system or nearby coastal waters. This discharge contributes to the ecological health of the region, supporting aquatic life and maintaining water quality in the sensitive Wadden Sea ecosystem, a UNESCO World Heritage site known for its biodiversity and migratory bird habitats.

The Meldorf plant's treated effluent flows into local streams and ditches that drain into the North Sea via the Elbe estuary or directly into the Wadden Sea. This coastal region is ecologically sensitive, supporting diverse marine life, including fish, crustaceans, and migratory birds. The Wadden Sea is a critical habitat for seals and serves as a major stopover for millions of birds along the East Atlantic Flyway. Proper wastewater treatment is essential to prevent nutrient pollution and protect this fragile ecosystem.
