Zaklad Oczyszczania Sciekow i zagospodaro wania Osadow - Jędrzychowice Wastewater Treatment Plant

Zaklad Oczyszczania Sciekow i zagospodaro wania Osadow is a municipal wastewater treatment plant located in Jędrzychowice, within the gmina Zgorzelec in the Lower Silesian Voivodeship of Poland. The facility serves an estimated population of 27,540, placing it in the medium agglomeration category under EU classification. As a Polish plant, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas. The regulatory framework ensures compliance with national and EU standards. The treated effluent is discharged into the local watershed, which ultimately drains into the Baltic Sea via the Oder River basin. The plant plays a key role in protecting downstream water quality and supporting the ecological health of the region's rivers and coastal environment.

The plant discharges into the local watershed within the Oder River basin, which flows northward into the Baltic Sea. This region supports diverse aquatic life and is part of an important migratory corridor for fish. The Baltic Sea is a sensitive brackish ecosystem that requires careful nutrient management to prevent eutrophication, making the plant's treatment performance critical for downstream environmental health.
