Klein Wanzleben I Wastewater Treatment Plant, Wanzleben-Börde, Saxony-Anhalt

Klein Wanzleben I is a municipal wastewater treatment plant located in the Remkersleben district of Wanzleben-Börde, in the Börde region of Saxony-Anhalt, Germany. The plant serves a small population of 1,180 residents, reflecting its role in a rural community. It operates under Germany's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which sets standards for treatment levels based on agglomeration size. The plant provides secondary treatment, which is the minimum required for agglomerations under 10,000 population equivalent in normal areas under the EU directive. Its designed capacity is 2,000 m³/day, and it currently discharges 298.63 m³/day of treated wastewater. The facility is part of the local wastewater infrastructure managed by the municipality or a regional water board. The treated effluent is discharged into local watercourses that drain into the Bode River, a tributary of the Saale, which flows into the Elbe and ultimately the North Sea. The plant helps protect the sensitive aquatic ecosystems of the Bode and Saale rivers, which support diverse freshwater species and are important for regional biodiversity.

The plant discharges into local streams that feed the Bode River, a major tributary of the Saale. The Saale flows into the Elbe, which empties into the North Sea. The Bode and Saale rivers support diverse aquatic life, including fish species such as barbel and chub, and their floodplains provide important habitats for birds and amphibians. The region's agricultural landscape means the plant's nutrient removal helps prevent eutrophication in downstream waters.
