COV Nemcice nad Hanou - Secondary Wastewater Treatment Plant in Dlouhá Ves, Olomoucký kraj

COV Nemcice nad Hanou is a municipal wastewater treatment plant located in Dlouhá Ves, a village in the Olomoucký kraj region of the Czech Republic. The plant serves a population of 2,094 and has a designed capacity of 3,500 cubic meters per day, with a current discharge volume of 277.22 cubic meters per day. As a secondary treatment facility, the plant provides biological treatment to remove organic matter and suspended solids. It operates under the Czech Republic's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The plant's capacity utilization is low, indicating ample reserve for future growth or seasonal variations. The treated effluent is discharged into local streams that drain into the Morava River, a major tributary of the Danube River system. The Morava River flows southward through the Czech Republic and Slovakia, eventually joining the Danube near Bratislava. The plant plays a key role in protecting the water quality of these downstream water bodies and the broader Danube basin ecosystem.

The plant discharges into small watercourses in the Haná region, which are part of the Morava River basin. The Morava River flows through agricultural and urban areas before joining the Danube, which ultimately reaches the Black Sea. The local watershed supports diverse aquatic life, including fish species such as barbel and chub, and the river corridor serves as an important migratory route for birds. The plant's secondary treatment helps reduce nutrient loads that could otherwise contribute to eutrophication in downstream reservoirs and the Danube Delta.
