Oczyszczalnia sciekow w Kamienicy Polskiej - Secondary Treatment Plant in Kolonia Poczesna, Poland

Oczyszczalnia sciekow w Kamienicy Polskiej is a municipal wastewater treatment plant located in Kolonia Poczesna, within the Czestochowa district of Slaskie province, Poland. The plant serves a population of approximately 2,305, classifying it as a small agglomeration under Polish and EU regulations. The facility provides secondary treatment, which is the minimum standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for inland freshwater discharges from agglomerations of this size. The plant has a designed capacity of 5,893.00 units and currently discharges 328.66 units, indicating significant spare capacity. The treated effluent is discharged into a local watercourse, which ultimately drains into the Warta River basin, part of the Oder River system flowing into the Baltic Sea. The plant plays a key role in protecting local streams and groundwater from untreated sewage, supporting the ecological health of the region.

The plant discharges into a tributary of the Warta River, which flows through central Poland before joining the Oder River and reaching the Baltic Sea. The local watershed supports diverse aquatic life and is used for agriculture and recreation. The secondary treatment reduces organic pollutants and suspended solids, helping to maintain water quality in downstream ecosystems.
