Munsterdorf Wastewater Treatment Plant, Münsterdorf, Schleswig-Holstein

Munsterdorf wastewater treatment plant is located in the municipality of Münsterdorf, in the Steinburg district of Schleswig-Holstein, Germany. The plant served a population of approximately 1,943 people and had a designed capacity of 3,000 cubic meters per day. It is now closed. The plant provided secondary treatment, which is the standard level required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The directive mandates secondary treatment for discharges to freshwater and estuaries from populations above 2,000, though smaller plants may also apply secondary treatment. The treated effluent was discharged into the local watershed, which ultimately drains into the Stör river, a tributary of the Elbe, and then into the North Sea. The plant's operation contributed to protecting the water quality of the Stör and Elbe rivers, which support diverse aquatic life and are important for regional ecology.

The plant discharged into the Stör river basin, which flows into the Elbe River and then into the North Sea. This watershed supports a variety of fish species and migratory birds. The Elbe estuary is an ecologically sensitive area that requires careful management of nutrient and pollutant loads to maintain water quality and biodiversity.
