Overview
KA Innerstetal is a municipal wastewater treatment plant serving Langelsheim, Niedersachsen, Germany. It treats wastewater for approximately 58,673 people under the EU Urban Waste Water Treatment Directive.
KA Innerstetal is a municipal wastewater treatment plant located in Langelsheim, in the district of Goslar, Niedersachsen, Germany. The plant serves a population of approximately 58,673 people, placing it in the medium agglomeration category under EU regulations. As a German plant, KA Innerstetal operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The directive also mandates more stringent treatment if the receiving waters are designated as sensitive areas, which is common in the region due to the ecological importance of local water bodies. The plant discharges treated wastewater into the Innerste River, a tributary of the Leine, which flows into the Aller and ultimately the Weser River, draining into the North Sea. The Innerste River supports diverse aquatic life and is an important watercourse in the Harz region, requiring careful management of nutrient loads to prevent eutrophication downstream.
Environmental context
The treated effluent from KA Innerstetal enters the Innerste River, which flows through the Harz mountains and joins the Leine River near Hildesheim. The Leine then merges with the Aller, which drains into the Weser and finally the North Sea. This river system supports a variety of fish species and provides habitat for migratory birds. The region's watershed is ecologically sensitive due to its role in maintaining water quality for downstream communities and natural areas.
