KA Wahle Wastewater Treatment Plant, Vechelde, Niedersachsen

KA Wahle is a municipal wastewater treatment plant located in Vechelade, a locality within the town of Vechelde in the district of Peine, Niedersachsen, Germany. The plant serves a population of around 20,200, placing it in the medium agglomeration category under EU regulations. As a German facility, KA Wahle operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations with a population equivalent between 10,000 and 150,000. The regulatory framework ensures compliance with national and EU standards for wastewater treatment. The treated effluent from KA Wahle is discharged into the local water system, which ultimately drains into the North Sea via the Weser River basin. The plant plays a key role in protecting the region's water quality, supporting aquatic life in the downstream rivers and contributing to the ecological health of the North Sea coastal environment.

KA Wahle discharges into the local water network that flows into the Oker River, a tributary of the Aller and Weser rivers, eventually reaching the North Sea. The Weser basin supports diverse aquatic habitats and is an important ecological corridor for migratory fish species. The plant's operations help maintain water quality in this sensitive river system.
