COV Ostrava Hermanice I Wastewater Treatment Plant, Ostrava, Czech Republic

COV Ostrava Hermanice I is a municipal wastewater treatment plant located in the Heřmanice district of Ostrava, in the Moravskoslezský kraj region of the Czech Republic. The plant serves a small population of around 1,013 residents, reflecting its role in a localized catchment area within the broader Ostrava urban environment. As a secondary treatment facility, it provides biological treatment to reduce organic pollutants and suspended solids before discharge. The plant operates under Czech national regulations that transpose the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations with a population equivalent (PE) under 2,000, the directive requires appropriate treatment, which in this case is secondary treatment. The plant has a designed capacity of 2,133 m³/day and a reported discharge volume of 168.55 m³/day, indicating it operates well below its capacity. The treated wastewater from COV Ostrava Hermanice I is discharged into the local water system, which ultimately drains into the Odra River basin. The Odra River flows through the Czech Republic, Poland, and Germany before reaching the Baltic Sea. This plant contributes to protecting the water quality of the Odra catchment, supporting aquatic life and downstream ecosystems.

The plant discharges into the Odra River basin, which flows northward through the Czech Republic, Poland, and Germany before emptying into the Baltic Sea. The Odra River supports diverse aquatic habitats and is an important ecological corridor in Central Europe. The region's industrial and urban activities necessitate effective wastewater treatment to maintain water quality and protect downstream environments, including sensitive areas such as floodplains and wetlands.
