KA Wischhafen - Advanced Wastewater Treatment Plant in Neuland, Niedersachsen

KA Wischhafen is an advanced wastewater treatment plant located in Neuland, part of the Wischhafen municipality in the Samtgemeinde Nordkehdingen, Stade district, Niedersachsen, Germany. The plant serves a population of approximately 5,748 people and has a design capacity of 6,600 m³/day, with an average discharge volume of 797.91 m³/day. As an advanced treatment facility, KA Wischhafen goes beyond secondary treatment to remove nutrients such as nitrogen and phosphorus, meeting the stringent requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC) for sensitive areas. The plant's scale places it in the small-to-medium agglomeration category, for which the directive mandates secondary treatment as a minimum, with advanced treatment required in sensitive catchments. The plant discharges treated effluent into the local water system, ultimately contributing to the Elbe River basin. The Elbe flows through northern Germany into the North Sea, supporting diverse aquatic ecosystems and serving as an important migratory corridor for fish species. The advanced treatment helps protect downstream water quality in this ecologically significant region.

KA Wischhafen discharges into the Elbe River basin, which drains into the North Sea. The Elbe estuary supports diverse aquatic life and is an important migratory corridor for fish species such as salmon and eel. The advanced treatment level helps reduce nutrient loads, protecting the downstream marine environment from eutrophication.
