Jezewo Wastewater Treatment Plant, Topolinek, Kuyavian-Pomeranian Voivodeship

Jezewo wastewater treatment plant is located in Topolinek, a village in the Kuyavian-Pomeranian Voivodeship of Poland. The facility serves a population of 2,811, classifying it as a small agglomeration under Polish and EU regulations. It operates as part of the municipal wastewater infrastructure for the Świecie county area. 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 1,185.00 m³/day and currently discharges 400.80 m³/day of treated wastewater. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into a local water body, which ultimately drains into the Vistula River basin. The Vistula flows northward through Poland into the Baltic Sea. The plant plays a role in protecting the local watershed and downstream aquatic ecosystems from untreated pollution.

The plant discharges into a local watercourse that is part of the Vistula River basin, Poland's largest river system. The Vistula flows into the Baltic Sea, a semi-enclosed sea with sensitive ecological conditions. The region's watershed supports diverse aquatic life and is important for migratory fish species. The plant's secondary treatment helps reduce nutrient loads, which is critical for preventing eutrophication in the Baltic Sea.
