Potulice Wastewater Treatment Plant, Kuyavian-Pomeranian Voivodeship, Poland

Potulice wastewater treatment plant is located in the village of Potulice, within Nakło nad Notecią commune, Kuyavian-Pomeranian Voivodeship, Poland. The facility serves a population of approximately 7,000 residents and operates under secondary treatment standards, which is typical for smaller agglomerations in Poland. The plant has a designed capacity of 7,775 cubic meters per day and reports a discharge volume of 999.8 cubic meters per day, indicating it operates well within its capacity. As a Polish facility, it must comply with national regulations transposing the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The treated wastewater is discharged into local surface waters, likely tributaries of the Noteć River, which flows into the Warta River and ultimately the Oder River and the Baltic Sea. The plant plays a key role in protecting the local aquatic environment from nutrient and organic pollution.

The plant discharges into the Noteć River basin, part of the Oder River catchment that drains into the Baltic Sea. The region supports diverse aquatic life and is important for migratory fish species. Effective treatment helps reduce eutrophication risks in downstream waters, including the Baltic Sea, which is sensitive to nutrient inputs.
