Krosno Odrzanskie Wastewater Treatment Plant - Krosno Odrzańskie, Poland

The Krosno Odrzanskie wastewater treatment plant is located in the town of Krosno Odrzańskie, in the województwo lubuskie region of western Poland. The facility serves a population of approximately 9,128 residents, classifying it as a medium-sized agglomeration under EU classification. The plant is situated near the Oder River, which is a major watercourse in the region. As a Polish wastewater treatment facility, the plant 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 plant's treatment processes are designed to meet these regulatory standards, ensuring that effluent quality complies with national and EU requirements. The treated wastewater is discharged into the local watershed, which ultimately drains into the Oder River. The Oder River flows northward through Poland and Germany before emptying into the Baltic Sea via the Szczecin Lagoon. The plant plays a crucial role in protecting the water quality of the Oder River and its downstream ecosystems, including the Baltic Sea, from nutrient pollution and other contaminants.

The plant discharges into the Oder River basin, which flows through western Poland and into the Baltic Sea via the Szczecin Lagoon. The Oder River supports diverse aquatic life and is an important migratory corridor for fish species. The Baltic Sea is a sensitive brackish water body prone to eutrophication, making nutrient removal from wastewater critical for downstream environmental health.
