Hamberge Buurredder Wastewater Treatment Plant, Hamberge, Germany

Hamberge Buurredder is a wastewater treatment plant located in Hamberge, a municipality in the Stormarn district of Schleswig-Holstein, Germany. The plant served a population of 1,500 and had a designed capacity of 1,500 m³/day, indicating it was sized for the local community. It is now closed, with its operational status listed as closed. The plant provided secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The directive mandates secondary treatment for all discharges from agglomerations with a population equivalent (PE) between 2,000 and 10,000, and Hamberge's population of 1,500 falls below this threshold, but the plant still met secondary treatment standards. The discharge volume was 379.61 m³/day, reflecting a utilization rate of about 25% of capacity. Given its inland location in Schleswig-Holstein, treated effluent likely discharges into a local stream or river within the Trave River basin, which flows into the Baltic Sea. Improving efficiency and environmental protection.

The plant is located inland in Schleswig-Holstein, approximately 10-50 km from the Baltic Sea coast. Its treated effluent likely entered a tributary of the Trave River, which flows into the Bay of Lübeck and the Baltic Sea. The Baltic Sea is a sensitive brackish water body with limited water exchange, making it vulnerable to nutrient pollution. Even small discharges can contribute to eutrophication, so secondary treatment helps reduce organic load and nutrients.
