KA Wustenbrand Gewerbegebiet Wastewater Treatment Plant, Oberlungwitz, Saxony

KA Wustenbrand Gewerbegebiet is a municipal wastewater treatment plant located in the Wustenbrand district of Oberlungwitz, in the state of Saxony, Germany. The plant serves a population of approximately 2,000 people and is designed to handle a capacity of 2,100 cubic meters per day, with an average daily discharge of 506.15 cubic meters. The plant provides secondary treatment, which is the standard biological treatment stage required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The directive mandates secondary treatment for all discharges from agglomerations with a population equivalent (PE) between 2,000 and 10,000, ensuring removal of organic matter and suspended solids. The treated effluent is discharged into the local water system, which ultimately drains into the Zwickauer Mulde river, a tributary of the Mulde, which flows into the Elbe and then into the North Sea. The plant plays a key role in protecting the water quality of the Zwickauer Mulde and downstream ecosystems, including the Elbe estuary.

The plant discharges into the Zwickauer Mulde river basin, which flows into the Mulde and then the Elbe River, eventually reaching the North Sea. The Elbe estuary supports diverse aquatic life and is an important migratory corridor for fish species. The region's water bodies are ecologically sensitive, requiring effective wastewater treatment to prevent nutrient enrichment and maintain biodiversity.
