COV Jirikov nova Wastewater Treatment Plant, Jiříkov, Germany

COV Jirikov nova is a wastewater treatment plant located in Jiříkov, in the Ústecký kraj region of Germany. It serves a small population of 937 people, providing secondary treatment to municipal wastewater. The plant has a designed capacity of 3000 m³/day and currently discharges 237.13 m³/day of treated effluent. As a German facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The plant's secondary treatment level meets the directive's standards for inland discharge, ensuring adequate removal of organic matter and suspended solids. The treated wastewater is discharged into local watercourses that ultimately drain into the North Sea via the Elbe River basin. The plant plays a key role in protecting the region's water quality, supporting aquatic life in downstream rivers and contributing to the ecological health of the broader watershed.

The plant discharges into local streams that flow into the Elbe River, which drains into the North Sea. The Elbe basin supports diverse aquatic ecosystems, including fish species such as salmon and eel. The plant's secondary treatment helps reduce nutrient loads, protecting downstream water quality and preventing eutrophication in the North Sea coastal zone.
