2544012008 KA Freden - Advanced Wastewater Treatment Plant in Freden (Leine), Germany

KA Freden is a municipal wastewater treatment plant located in Freden (Leine), a town in the district of Hildesheim, Niedersachsen, Germany. The plant serves a population of about 4,050 people and is designed to handle a capacity of 7,500 cubic meters per day, with an actual discharge volume of 828.55 m³/day. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. As a German facility, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires advanced treatment for agglomerations discharging into sensitive areas. The plant's advanced level ensures compliance with stringent effluent standards. The treated effluent is discharged into the Leine River, a tributary of the Aller and Weser rivers, which ultimately flows into the North Sea. The plant plays a key role in protecting the water quality of the Leine and downstream ecosystems, supporting aquatic life and recreational uses.

The plant discharges into the Leine River, which flows into the Aller and then the Weser, eventually reaching the North Sea. The Leine River supports diverse aquatic habitats and is used for recreation and agriculture. Advanced treatment helps minimize nutrient loading, protecting downstream waters from eutrophication and maintaining ecological balance.
