ZKA Kiesdorf Wastewater Treatment Plant, Kiesdorf auf dem Eigen, Saxony

ZKA Kiesdorf is a former municipal wastewater treatment plant located in Kiesdorf auf dem Eigen, a district of Schönau-Berzdorf in the Görlitz region of Saxony, Germany. The plant served a population of approximately 5,065 people before its closure. As a German facility, the plant would have operated under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The plant's closure may reflect consolidation of wastewater services in the region. The plant's receiving waters are part of the local watershed, which drains via the Neiße River into the Oder River and ultimately the Baltic Sea. The area is characterized by agricultural and rural landscapes, with the Neiße River supporting diverse aquatic life.

The plant's treated effluent would have discharged into local watercourses that flow into the Neiße River, a tributary of the Oder River. The Oder River drains into the Baltic Sea, a sensitive marine environment. The watershed supports diverse aquatic habitats and is important for migratory fish species. The closure of the plant may have reduced local nutrient loads, benefiting downstream water quality.
