KA Bad Salzdetfurth Wastewater Treatment Plant, Bad Salzdetfurth, Niedersachsen

KA Bad Salzdetfurth is a former municipal wastewater treatment plant located in Bad Salzdetfurth, a town in the district of Hildesheim, Niedersachsen, Germany. The plant served a population of approximately 8,475 residents before its closure. As a small agglomeration, it would have been subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for inland plants serving between 2,000 and 10,000 population equivalent. The plant is now closed and no longer operational. During its operation, it would have been required to meet German wastewater standards under the Abwasserverordnung (Wastewater Ordinance), which implements EU directives. For a plant of this size, typical treatment includes mechanical and biological stages to reduce organic load and nutrients before discharge. The area drains via the Lamme River, a tributary of the Innerste, which flows into the Leine and eventually the Weser River, reaching the North Sea. Improving efficiency and environmental protection.

The plant is located inland in the Leine-Weser river basin. Treated effluent would have discharged into local streams that feed the Lamme River, a tributary of the Innerste. The Innerste joins the Leine, which flows into the Weser and ultimately the North Sea. The watershed supports diverse aquatic life and is part of a larger river system that requires careful nutrient management to prevent eutrophication in downstream waters.
