Kobierzyce Wastewater Treatment Plant, Pełczyce, Poland

The Kobierzyce wastewater treatment plant is located in Pełczyce, within the gmina Kobierzyce in the Lower Silesian Voivodeship of Poland. This facility serves a small population of approximately 1,796 residents, reflecting its role in a rural or suburban setting. The plant is part of Poland's municipal wastewater infrastructure, which operates under the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU directive for agglomerations of this size. With a designed capacity of 3,083 m³/day and an actual discharge volume of 256.08 m³/day, the plant operates well below its capacity, indicating potential for future growth or seasonal variations. The facility is not located near the coast, reducing direct marine discharge risks. The treated effluent is discharged into local water bodies within the Odra River basin, which ultimately flows into the Baltic Sea. The plant's advanced treatment helps protect downstream ecosystems, including the Odra River and its tributaries, which support diverse aquatic life and are important for regional biodiversity.

The plant discharges into local streams that are part of the Odra River basin. The Odra flows through Poland and Germany before reaching the Baltic Sea, a sensitive marine environment. The advanced treatment at Kobierzyce reduces nutrient loads, helping to prevent eutrophication in downstream waters and supporting the ecological health of the Baltic Sea.
