Złotów Wastewater Treatment Plant, Blękwit | Poland

The Złotów wastewater treatment plant is located in Blękwit, within the Złotów commune of Wielkopolskie Voivodeship, Poland. It serves a population of around 18,117 people, placing it in the medium agglomeration category under Polish and EU regulations. The plant is situated in a rural-urban setting in northern Greater Poland. As a Polish facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. Polish national regulations transpose the directive, and the plant is expected to meet effluent standards for biological oxygen demand, suspended solids, and nutrients if discharging to sensitive areas. The plant's scale suggests it likely employs biological treatment. The plant discharges treated wastewater into local watercourses that drain toward the Noteć River basin, part of the Oder River catchment flowing into the Baltic Sea. Its operation helps protect downstream aquatic ecosystems and supports water quality in the region's agricultural landscape.

The Złotów plant discharges into the local watershed, which feeds into the Noteć River, a tributary of the Warta River, ultimately reaching the Oder River and the Baltic Sea. The downstream environment includes agricultural areas and natural habitats that depend on good water quality. The plant's treatment helps reduce nutrient loading, which is critical for preventing eutrophication in the Baltic Sea, a sensitive marine ecosystem.
