Tuszyn Wastewater Treatment Plant, Tuszyn, Poland | Secondary Treatment for 5,669 People

The Tuszyn wastewater treatment plant is located in the town of Tuszyn, within the województwo łódzkie region of central Poland. It serves a population of approximately 5,669 residents, classifying it as a small to medium agglomeration under Polish and EU regulations. The plant is situated inland, away from coastal areas, and its operations are part of the municipal wastewater infrastructure for the local community. The plant provides secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The designed capacity of the plant is 9,073 m³ per day, with a reported discharge volume of 808.31 m³ per day, indicating that the plant operates well below its maximum capacity. The treated effluent is discharged into local water bodies, likely tributaries of the larger river systems in the region. The plant plays a key role in protecting the water quality of the Vistula River basin, which ultimately drains into the Baltic Sea. By reducing pollutant loads, the facility helps maintain the ecological health of downstream aquatic environments and supports the region's compliance with EU water quality standards.

The Tuszyn plant discharges treated wastewater into local streams that are part of the Vistula River basin. The Vistula flows northward through Poland and empties into the Baltic Sea. The region's watershed supports diverse aquatic life and is important for migratory fish species. The plant's secondary treatment helps reduce nutrient and organic pollution, mitigating eutrophication risks in the Baltic Sea.
