KA Muhlau Wastewater Treatment Plant, Penig, Saxony

KA Muhlau is a wastewater treatment plant located in Penig, within the Mittelsachsen district of Saxony, Germany. The plant serves a population of around 2,000 residents, classifying it as a small agglomeration under German and EU regulations. It is situated in the Burgstädter Straße area, providing essential sanitation services to the local community. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 2,900 cubic meters per day and a reported discharge volume of 300 cubic meters per day, the facility operates well within its capacity. Advanced treatment typically includes nutrient removal, ensuring high-quality effluent. The treated wastewater is discharged into a receiving water body that ultimately drains into the Zwickauer Mulde river, a tributary of the Mulde and Elbe river systems. This contributes to the overall water quality of the Elbe basin, which flows into the North Sea. The plant plays a key role in protecting local water resources and downstream ecosystems.

KA Muhlau discharges into a local watercourse that flows into the Zwickauer Mulde river, part of the Mulde and Elbe river basins. The Elbe river system supports diverse aquatic life and is an important ecological corridor in Central Europe. The advanced treatment level helps minimize nutrient loading, protecting downstream water quality in the Elbe and ultimately the North Sea.
