COV Cesky Tesin Horni Zukov - Closed Secondary Wastewater Treatment Plant in Chotěbuz, Czech Republic

COV Cesky Tesin Horni Zukov is a wastewater treatment plant located in Chotěbuz, a village in the Moravskoslezský kraj of the Czech Republic. The plant was designed to serve the local population and is now closed. As a secondary treatment facility, it would have provided biological treatment to reduce organic matter and suspended solids. Under Czech regulations aligned with the EU Urban Waste Water Treatment Directive, plants of this scale are expected to meet secondary treatment standards. The plant's closure may reflect consolidation of regional wastewater services. The area drains into the Olše River, a tributary of the Oder River, which flows into the Baltic Sea. The Oder basin supports diverse aquatic ecosystems and is an important migratory corridor for fish.

The plant is located inland in the Moravskoslezský region, within the Oder River basin. The nearest major watercourse is the Olše River, which joins the Oder River near Ostrava. The Oder flows northward to the Baltic Sea, supporting a range of aquatic life and serving as a key waterway in Central Europe. The region's industrial history has necessitated careful wastewater management to protect downstream ecosystems.
