KA Alme Riehe_ostrum Wastewater Treatment Plant, Bad Salzdetfurth, Niedersachsen

KA Alme Riehe_ostrum is a municipal wastewater treatment plant located in the Östrum district of Bad Salzdetfurth, in the state of Niedersachsen, Germany. The plant serves a population of approximately 12,742, placing it in the medium agglomeration category under European regulations. As a German facility, the plant is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The plant's treatment processes and capacity are managed in accordance with national standards, ensuring compliance with effluent quality requirements. The treated wastewater is discharged into local watercourses that eventually drain into the Leine River, a tributary of the Aller and Weser rivers, which flow into the North Sea. The plant plays a key role in protecting the water quality of the Leine basin and downstream ecosystems.

The plant discharges into the Leine River basin, which flows through Niedersachsen and joins the Aller River, ultimately reaching the Weser and the North Sea. The Leine supports diverse aquatic life and is an important corridor for migratory fish. Protecting this watershed is critical for maintaining regional water quality and ecological health.
