Overview
KA Delligsen is a municipal wastewater treatment plant serving Alfeld (Leine) in Niedersachsen, Germany. It treats wastewater for approximately 8,788 people under the EU Urban Waste Water Treatment Directive.
KA Delligsen is a municipal wastewater treatment plant located in Alfeld (Leine), within the Landkreis Hildesheim district of Niedersachsen, Germany. The plant serves a population of approximately 8,788, classifying it as a small to medium agglomeration under European Union regulations. As a German wastewater facility, KA Delligsen operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations of this size. The plant's treatment processes are designed to meet national standards set by the German Water Resources Act (Wasserhaushaltsgesetz) and relevant state regulations. The plant discharges treated effluent into the local water system, which ultimately drains into the Leine River, a tributary of the Aller and Weser rivers. The Weser flows into the North Sea, making this plant part of the Weser basin. The surrounding region is characterized by agricultural and rural landscapes, with the Leine River supporting diverse aquatic life and serving as an important ecological corridor.
Environmental context
The plant's treated effluent enters the local watershed, which drains into the Leine River. The Leine flows northward through Niedersachsen, joining the Aller River, which then merges with the Weser River. The Weser discharges into the North Sea, a sensitive marine environment. The Leine River supports diverse fish populations and riparian habitats, and its water quality is critical for downstream ecosystems and recreational use.
