ZKA Rodewitz Wastewater Treatment Plant, Schirgiswalde-Kirschau, Saxony

ZKA Rodewitz is a municipal wastewater treatment plant located in the town of Schirgiswalde-Kirschau, in the state of Saxony, Germany. The plant serves a population equivalent of approximately 37,000 people, classifying it as a medium-sized agglomeration under European Union regulations. As a German wastewater treatment facility, ZKA Rodewitz operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The plant is also subject to Germany's national water management laws, which enforce strict effluent standards to protect water quality. The treated effluent from ZKA Rodewitz is discharged into the local water system, which ultimately drains into the Spree River basin. The Spree flows through the Lusatian region and into Berlin, eventually reaching the Havel River and the Elbe, which empties into the North Sea. The plant plays a key role in maintaining the ecological health of this important river system.

ZKA Rodewitz discharges into the Spree River basin, a major tributary of the Havel and Elbe rivers that flows through eastern Germany. The Spree supports diverse aquatic life and is an important water source for the region. Downstream, the river passes through the Spreewald biosphere reserve, a ecologically sensitive wetland area. The plant's treatment performance is critical to preventing nutrient pollution and protecting downstream habitats.
