COV Horazdovice Wastewater Treatment Plant, Horažďovice, Plzeňský kraj

COV Horazdovice is a municipal wastewater treatment plant located in Horažďovice, a town in the Plzeňský kraj region of the Czech Republic. The plant serves a population of approximately 4,158 people, classifying it as a small agglomeration under EU standards. It is situated inland, far from coastal areas, and discharges treated effluent into local watercourses. The plant provides secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant has a designed capacity of 9,500 m³/day, with an average discharge volume of 897.06 m³/day, indicating ample capacity for current loads. The treated wastewater from COV Horazdovice ultimately drains into the Otava River, a tributary of the Vltava River, which flows into the Elbe River and eventually reaches the North Sea. This river system supports diverse aquatic life and is important for regional water quality. The plant's operation helps protect the Otava River and downstream ecosystems from pollution.

COV Horazdovice discharges into the Otava River, which flows through the Plzeňský kraj region and joins the Vltava River. The Vltava then merges with the Elbe, which empties into the North Sea. This river network supports a variety of fish species and aquatic habitats. The plant's secondary treatment reduces organic pollutants and suspended solids, helping to maintain water quality in this ecologically sensitive watershed.
