Czermin Wastewater Treatment Plant, Korzkwy, Poland

Czermin is a wastewater treatment plant located in Korzkwy, within the gmina Pleszew, powiat pleszewski, województwo wielkopolskie, Poland. It serves a small population of 277 people, reflecting its role in a rural or small community setting. The plant provides secondary treatment, which is the standard biological treatment stage required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The designed capacity of 848.00 m³/day indicates the plant's potential to handle higher loads, while the actual discharge volume is 39.50 m³/day. The treated effluent is discharged into a local water body, contributing to the protection of the Warta River basin and ultimately the Oder River system, which flows into the Baltic Sea. The plant helps maintain water quality in the region's surface waters, supporting aquatic life and downstream ecosystems.

The plant discharges into a local watercourse that is part of the Warta River basin, a major tributary of the Oder River. The Oder flows into the Szczecin Lagoon and then the Baltic Sea. The region's watershed supports diverse aquatic habitats and is important for migratory fish species. Secondary treatment reduces organic pollutants and nutrients, helping to prevent eutrophication in downstream waters.
