KA Barsinghausen Wastewater Treatment Plant - Barsinghausen, Niedersachsen

KA Barsinghausen is a municipal wastewater treatment plant located in Barsinghausen, Niedersachsen, Germany. It serves a population of approximately 46,617, placing it in the medium agglomeration category under EU regulations. The plant is situated in the region of Hannover, an area characterized by mixed urban and agricultural land use. As a German plant serving over 15,000 population equivalents, KA Barsinghausen is required to meet secondary treatment standards under the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of this size, the directive mandates biological treatment to reduce organic matter and suspended solids. It is expected to comply with national and EU effluent quality standards. The plant discharges treated wastewater into local watercourses that ultimately drain into the Weser River basin, which flows to the North Sea. The receiving waters support diverse aquatic life and are part of a regionally important hydrological network. Proper treatment at this facility helps protect downstream ecosystems and water quality in the Weser catchment.

The treated effluent from KA Barsinghausen enters local streams that feed into the Weser River system, which flows through central Germany before reaching the North Sea. The Weser basin supports a variety of fish species, including salmonids in its upper reaches, and provides habitat for migratory birds. The plant's location in a mixed urban and agricultural area means its discharge must be carefully managed to prevent nutrient enrichment and maintain ecological balance in the downstream water bodies.
