COV Suchdol nad Luznici Wastewater Treatment Plant, Suchdol nad Lužnicí

COV Suchdol nad Luznici is a municipal wastewater treatment plant located in Suchdol nad Lužnicí, in the Jihočeský kraj region of the Czech Republic. The plant serves a population of 1,900, classifying it as a small agglomeration under EU standards. It operates under the Czech national regulations that implement the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant provides secondary treatment, which is the minimum required for discharges into freshwater bodies under the directive. Its designed capacity is 4,830 m³/day, with an actual discharge volume of 532.65 m³/day, indicating ample reserve capacity. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into the local watershed, which ultimately drains into the Lužnice River, a tributary of the Vltava River. The Vltava flows through Prague and joins the Elbe River, which reaches the North Sea. The plant plays a key role in protecting the water quality of these rivers and the downstream ecosystem.

The plant discharges into the Lužnice River basin, which flows into the Vltava River, a major waterway in the Czech Republic. The Vltava eventually joins the Elbe River, which drains into the North Sea. This watershed supports diverse aquatic life and provides drinking water for downstream communities. Secondary treatment helps reduce nutrient loads, mitigating eutrophication risks in the river system.
