KA Wildenfels - Closed Advanced Wastewater Treatment Plant in Wildenfels, Saxony

KA Wildenfels is a former wastewater treatment plant located in Wildenfels, a town in the Zwickau district of Saxony, Germany. The plant was designed to serve a population of 1,838 and had a designed capacity of 1,800 cubic meters per day. It is now closed and no longer in operation. The plant provided advanced treatment, which goes beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Advanced treatment typically includes nutrient removal to protect sensitive water bodies. The plant's discharge volume was recorded at 465.15 cubic meters per day. The treated effluent from the plant would have been discharged into local watercourses that drain into the Zwickauer Mulde river, a tributary of the Mulde river system, which ultimately flows into the Elbe River and then into the North Sea. The plant's operation contributed to protecting the water quality of these rivers and the downstream ecosystem.

The plant is located inland in the Erzgebirge (Ore Mountains) region of Saxony. Its discharge would have entered local streams feeding the Zwickauer Mulde river, part of the Elbe basin. The Elbe River flows through Germany and the Czech Republic before reaching the North Sea, supporting diverse aquatic life and serving as an important migratory corridor for fish. The advanced treatment level helped reduce nutrient loads, protecting downstream waters from eutrophication.
