Oczyszczalnia Sciekow Kosorowice - Secondary Wastewater Treatment Plant in Kosorowice, Poland

Oczyszczalnia Sciekow Kosorowice is a municipal wastewater treatment plant located in Kosorowice, within the Opole Voivodeship of southern Poland. The facility serves a population of approximately 5,248 residents, classifying it as a small agglomeration under Polish and EU regulations. The plant is situated in a rural area near the city of Opole, contributing to local sanitation and environmental protection. The plant provides secondary treatment, which is the minimum standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 15,015 cubic meters per day and a current discharge volume of 748.28 cubic meters per day, the facility operates well below its capacity, indicating potential for future growth. The treatment process likely involves biological treatment to reduce organic matter and suspended solids before discharge. The treated effluent is discharged into local watercourses that eventually drain into the Oder River basin. The Oder River flows northward to the Baltic Sea, making the plant's operations important for downstream water quality. The surrounding region includes agricultural areas and small settlements, and the plant helps protect local streams and groundwater from untreated sewage contamination.

The plant discharges into small water bodies within the Oder River basin, which ultimately flows into the Baltic Sea. The Oder basin supports diverse aquatic life and is an important ecological corridor in Central Europe. Effective wastewater treatment at Kosorowice helps reduce nutrient loading and organic pollution, protecting downstream habitats and water quality in the Baltic Sea region.
