Overview
KA Herrenhausen is a large wastewater treatment plant serving Seelze, Niedersachsen, Germany. It treats wastewater from over 530,000 people under the EU Urban Waste Water Treatment Directive.
KA Herrenhausen is a major wastewater treatment facility located in Seelze, Niedersachsen, Germany. Serving a population of over 530,000, it is classified as a large agglomeration under EU regulations. The plant is situated in the Leine river basin, which ultimately drains into the North Sea. As a large German treatment plant, KA Herrenhausen is expected to meet stringent standards under the EU Urban Waste Water Treatment Directive (91/271/EEC). This directive requires tertiary treatment for agglomerations over 150,000 population equivalents in sensitive areas, which applies to much of Germany. The plant's capacity and treatment processes are designed to comply with these high standards. The treated effluent from KA Herrenhausen is discharged into the Leine River, a tributary of the Aller and Weser rivers, which flow into the North Sea. The plant plays a critical role in protecting the water quality of the Leine and downstream ecosystems, including the Weser estuary and the Wadden Sea, a region of high ecological importance.
Environmental context
KA Herrenhausen discharges into the Leine River, which flows through Niedersachsen before joining the Aller and Weser rivers, ultimately reaching the North Sea. The Weser estuary and the Wadden Sea are ecologically sensitive areas that support diverse aquatic life and serve as important migratory corridors for birds. The plant's advanced treatment helps reduce nutrient loads, protecting these downstream environments from eutrophication.
