ZKA Reichenbach - Advanced Wastewater Treatment in Reichenbach/Oberlausitz, Saxony

ZKA Reichenbach is an advanced wastewater treatment facility located in Reichenbach/Oberlausitz, Saxony, Germany. The plant serves a population of 5,403 and is part of the municipal infrastructure for the region. It operates with a designed capacity of 8,000 cubic meters per day and currently discharges an average of 810.45 cubic meters of treated wastewater daily. As an advanced treatment plant, ZKA Reichenbach goes beyond secondary treatment to remove nutrients such as nitrogen and phosphorus, ensuring high-quality effluent. This level of treatment is typical for plants in sensitive areas under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates advanced treatment for agglomerations serving over 10,000 people in sensitive catchments. Although the plant serves a smaller population, its advanced status reflects local environmental requirements. The treated effluent from ZKA Reichenbach is discharged into the local water system, ultimately draining into the Black Elster River, a tributary of the Elbe River, which flows into the North Sea. The plant plays a crucial role in protecting the water quality of the Elbe basin, supporting aquatic life and downstream ecosystems. Its advanced treatment helps reduce nutrient loading, which is vital for preventing eutrophication in the North Sea.

ZKA Reichenbach discharges into the local water network that feeds the Black Elster River, a tributary of the Elbe River. The Elbe flows through Germany and the Czech Republic before emptying into the North Sea. The plant's advanced treatment reduces nutrient pollution, protecting downstream aquatic habitats and supporting biodiversity in the Elbe estuary, an ecologically important area for migratory fish and waterbirds.
