Miedzyborz Wastewater Treatment Plant, Międzybórz, Poland

The Miedzyborz wastewater treatment plant is located in Międzybórz, a town in the Lower Silesian Voivodeship of Poland. This facility serves a population of approximately 1,574 residents, reflecting its role in managing municipal wastewater for a small agglomeration. The plant employs advanced treatment processes, which go beyond the secondary treatment standards required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 7,926 cubic meters per day and an actual discharge volume of 224.43 cubic meters per day, the plant operates well below its capacity, indicating potential for future growth or seasonal variability. The treated effluent is discharged into local water bodies, contributing to the protection of the Odra River basin, which ultimately drains into the Baltic Sea. The advanced treatment helps reduce nutrient loads and protects downstream aquatic ecosystems, supporting biodiversity in the region.

The plant discharges into local streams that are part of the Odra River basin, which flows northward into the Baltic Sea. The Baltic Sea is a brackish water body sensitive to nutrient pollution, and advanced treatment at this plant helps mitigate eutrophication risks. The surrounding area includes agricultural lands and small forests, where maintaining water quality is essential for local wildlife and downstream habitats.
