KA Sievershausen - Advanced Wastewater Treatment Plant in Lehrte, Niedersachsen

KA Sievershausen is an advanced wastewater treatment plant located in the Sievershausen district of Lehrte, in the Region Hannover, Niedersachsen, Germany. The plant serves a population of 2,318 and is part of the municipal wastewater infrastructure for the area. As an advanced treatment facility, KA Sievershausen goes beyond secondary treatment to remove nutrients and other pollutants, meeting stringent German and EU standards. The plant has a designed capacity of 4,200 m³/day and currently discharges an average of 513.70 m³/day of treated wastewater, indicating significant reserve capacity. The treated effluent from KA Sievershausen is discharged into local watercourses that ultimately drain into the Leine River, a tributary of the Aller and Weser river systems, which flow into the North Sea. The plant's advanced treatment helps protect the ecological health of these receiving waters, supporting aquatic life and downstream water quality.

The plant discharges into local streams that feed into the Leine River, part of the Weser basin, which flows to the North Sea. The Leine and its tributaries support diverse aquatic ecosystems, including fish species such as brown trout and grayling. Advanced treatment at this plant reduces nutrient loading, helping to prevent eutrophication in downstream waters and the sensitive Wadden Sea area.
