Lentfohrden Wastewater Treatment Plant, Lentföhrden, Schleswig-Holstein

Lentfohrden wastewater treatment plant is located in Lentföhrden, a municipality in the district of Segeberg, Schleswig-Holstein, Germany. The plant serves a population of approximately 2,500, classifying it as a small agglomeration under German and EU regulations. The facility employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive for inland plants. With a designed capacity of 2,400 cubic meters per day and a discharge volume of about 348 cubic meters per day, the plant operates well within its capacity, ensuring effective treatment of municipal wastewater. The treated effluent is discharged into local inland waters, likely tributaries of the Stör or other small rivers in the region, which eventually drain into the Elbe River and then the North Sea. The advanced treatment helps protect the sensitive aquatic ecosystems of Schleswig-Holstein, a region known for its wetlands and biodiversity.

The plant discharges into small streams that flow into the Stör river system, a tributary of the Elbe. The Elbe carries water to the North Sea, supporting diverse habitats including tidal flats and estuaries. The advanced treatment reduces nutrient loads, protecting downstream waters from eutrophication and preserving ecological balance in this agriculturally influenced region.
