COV Milin Wastewater Treatment Plant, Milín, Středočeský kraj

COV Milin is a wastewater treatment plant located in Milín, a town in the Středočeský kraj region of the Czech Republic. The plant serves a population of approximately 1,123 residents, classifying it as a small agglomeration under Czech and EU regulations. The plant provides secondary treatment, which is the minimum standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. The plant has a designed capacity of 2,300 cubic meters per day, and the current discharge volume is 326.48 cubic meters per day, indicating operational headroom. The treated effluent from COV Milin is discharged into the local watershed, which ultimately drains into the Vltava River basin and then into the Elbe River, flowing to the North Sea. This discharge supports the ecological health of downstream water bodies and aligns with Czech national water quality objectives.

COV Milin discharges into the local stream network, which flows into the Vltava River, a major tributary of the Elbe River. The Elbe basin supports diverse aquatic life and is an important ecological corridor in Central Europe. The plant's secondary treatment helps reduce nutrient and organic loads, protecting downstream habitats from eutrophication and maintaining water quality for sensitive species.
