Oczyszczalnia Gidle - Secondary Wastewater Treatment Plant in Gidle, Poland

Oczyszczalnia Gidle is a municipal wastewater treatment plant located in Gidle, a town in the radomszczański district of województwo łódzkie, Poland. The plant serves a population of 788, classifying it as a small agglomeration under Polish and EU regulations. The plant provides secondary treatment, which is the minimum standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. The designed capacity is 2,917 m³/day, with a current discharge volume of 112.36 m³/day, indicating significant reserve capacity. The treated effluent is discharged into local watercourses that ultimately drain into the Warta River basin, a major tributary of the Oder River. This contributes to the ecological health of the Oder River system, which flows into the Baltic Sea. The plant plays a key role in protecting local streams and groundwater from untreated sewage.

The plant discharges into the Warta River basin, part of the Oder River catchment that flows northward to the Baltic Sea. The region's aquatic ecosystems support diverse fish and invertebrate populations, and the plant's secondary treatment helps reduce nutrient loading, mitigating eutrophication risks in downstream waters.
