KA Edemissen Wastewater Treatment Plant, Edemissen, Niedersachsen

KA Edemissen is a municipal wastewater treatment plant located in Edemissen, in the Landkreis Peine district of Niedersachsen, Germany. The plant serves a population of around 5,900, classifying it as a small agglomeration under the EU Urban Waste Water Treatment Directive (91/271/EEC). As a German plant of this scale, it is expected to provide at least secondary treatment in accordance with EU standards. The plant's discharge is regulated under the German Water Resources Act (WHG) and the Wastewater Ordinance (AbwV), which set strict effluent limits for parameters such as BOD, COD, nitrogen, and phosphorus. The treated effluent is discharged into local watercourses that eventually drain into the North Sea via the Weser or Elbe river systems. The surrounding region is characterized by agricultural land use, and the plant plays a key role in protecting local groundwater and surface water quality.

The plant's treated wastewater enters small streams in the Edemissen area, which flow into the Fuhse or Oker rivers, tributaries of the Aller and Weser rivers. The Weser ultimately discharges into the North Sea. The region's flat terrain and intensive agriculture make nutrient management critical to prevent eutrophication in downstream waters.
