KA Salzgitter Ringelheim - Secondary Wastewater Treatment Plant in Salzgitter, Germany

KA Salzgitter Ringelheim is a municipal wastewater treatment plant located in the Ringelheim district of Salzgitter, in the state of Niedersachsen, Germany. The plant serves a population of 2,816 and is part of the region's wastewater infrastructure. The plant provides secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 4,000 m³/day and an average discharge volume of 468.19 m³/day, the plant operates well within its capacity. The treated effluent is discharged into local watercourses that eventually drain into the Innerste River, a tributary of the Leine, which flows into the Aller and then the Weser River. The Weser ultimately reaches the North Sea. The plant plays a key role in protecting the water quality of these downstream ecosystems.

The plant discharges into the Innerste River basin, which flows into the Leine, Aller, and Weser rivers before reaching the North Sea. The Weser estuary supports diverse aquatic life and is an important migratory corridor for fish species. The plant's secondary treatment helps reduce organic pollution and protect the ecological health of this river system.
