Krosnowice Wastewater Treatment Plant - Secondary Treatment in Województwo Dolnośląskie

The Krosnowice wastewater treatment plant is located in the village of Krosnowice, within gmina Kłodzko, województwo dolnośląskie, Poland. It serves a population of approximately 3,848 people, classifying it as a small agglomeration under Polish and EU regulations. 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. It has a designed capacity of 1,386.00 thousand m³/year and treats an average discharge volume of 548.66 thousand m³/year. The treated effluent is discharged into a local watercourse that eventually flows into the Nysa Kłodzka River, a tributary of the Oder River. The Oder River drains into the Baltic Sea, making the plant part of the Oder basin. The surrounding region is characterized by the Sudetes mountain range, and the plant helps protect local streams and the downstream aquatic ecosystem from nutrient pollution.

The plant discharges into a local watercourse that feeds into the Nysa Kłodzka River, which flows northward to join the Oder River. The Oder River ultimately reaches the Baltic Sea, making this plant part of a transboundary basin. The Sudetes region supports diverse aquatic life, and the plant's secondary treatment helps reduce organic load and nutrient inputs, protecting downstream habitats from eutrophication.
