Overview
KA Langenhagen is a wastewater treatment plant serving 123,000 people in Langenhagen, Niedersachsen, Germany. It operates under the EU Urban Waste Water Treatment Directive.
KA Langenhagen is a municipal wastewater treatment plant located in Langenhagen, Niedersachsen, Germany, serving a population of approximately 123,000. The plant is situated in the Region Hannover and is part of the region's wastewater infrastructure. As a large agglomeration under the EU Urban Waste Water Treatment Directive (91/271/EEC), the plant is required to provide secondary treatment and, if discharging to sensitive areas, tertiary treatment. The directive mandates that agglomerations over 10,000 population equivalent (PE) must have collecting systems and treatment, with stricter standards for larger plants. The plant's treated effluent likely discharges into a local watercourse that flows into the Leine River, a tributary of the Aller and Weser rivers, ultimately reaching the North Sea. This downstream connection underscores the plant's role in protecting regional water quality and aquatic ecosystems.
Environmental context
The plant's treated effluent is expected to enter a local watercourse that drains into the Leine River, which flows through Niedersachsen before joining the Aller and Weser rivers. The Weser River discharges into the North Sea, making the plant part of a larger watershed that supports diverse aquatic life and migratory fish species. The region's water bodies are ecologically sensitive, requiring effective nutrient removal to prevent eutrophication.
