1534012001 KA Lutter - Advanced Wastewater Treatment Plant in Langelsheim, Germany

1534012001 KA Lutter is an advanced wastewater treatment plant located in the Lutter am Barenberge district of Langelsheim, in the Landkreis Goslar, Niedersachsen, Germany. The plant serves a population of approximately 2,932 and has a designed capacity of 9,200 m³/day, with a current discharge volume of 687.60 m³/day. As an advanced treatment facility, the plant goes beyond secondary treatment to remove nutrients and other pollutants, ensuring high-quality effluent. This aligns with the requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates advanced treatment for sensitive areas. The plant's scale places it in the small agglomeration category under the directive. The treated wastewater is discharged into local watercourses that drain into the Innerste River, a tributary of the Leine, which flows into the Aller and ultimately the Weser River. The Weser drains into the North Sea. The plant plays a key role in protecting the water quality of the Innerste and downstream ecosystems.

The plant discharges into the Innerste River basin, which flows through the Harz region before joining the Leine. The Innerste supports diverse aquatic life and is an important corridor for migratory fish. The treated effluent contributes to the overall water quality of the Weser River system, which drains into the North Sea. The region's mixed urban and agricultural land use makes nutrient removal critical to prevent eutrophication in downstream waters.
