Kozminek Wastewater Treatment Plant, Koźminek | Poland

The Kozminek wastewater treatment plant is located in the town of Koźminek, within the powiat kaliski of województwo wielkopolskie, Poland. It serves a population of approximately 2,470 people, making it a small-scale municipal facility. The plant is situated inland, away from coastal areas, and its operations are part of the region's water management infrastructure. The plant provides secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 900 cubic meters per day and a current discharge volume of 352.18 cubic meters per day, the facility operates well within its capacity. The treatment process ensures that effluent meets regulatory standards before discharge. The treated wastewater is discharged into local rivers that ultimately drain into the Oder River basin, which flows into the Baltic Sea. The plant plays a key role in protecting the local watershed from pollution, supporting aquatic life and downstream water quality in the region's river systems.

The Kozminek plant discharges into local streams that are part of the Oder River basin, which flows northward into the Baltic Sea. The watershed supports diverse aquatic habitats and is important for regional biodiversity. The plant's secondary treatment helps reduce nutrient loads and organic pollutants, mitigating eutrophication risks in downstream water bodies.
