Tczow Wastewater Treatment Plant, Tczów, Mazowieckie, Poland

The Tczow wastewater treatment plant is located in Tczów, a town in the Mazowieckie voivodeship of Poland. It serves a small population of approximately 1,199 people, reflecting its role in a rural or small urban community. The plant is part of Poland's municipal wastewater infrastructure, which is regulated under the EU Urban Waste Water Treatment Directive (UWWTD). The plant provides secondary treatment, which is the standard biological treatment required under the UWWTD for agglomerations of this size. It has a designed capacity of 4,500 m³/day, with an actual discharge volume of 170.96 m³/day, indicating that the plant operates well below its capacity. This suggests potential for future growth or seasonal variations in flow. The treated effluent is discharged into a local water body, which ultimately drains into the Vistula River basin. The Vistula is Poland's longest river and flows into the Baltic Sea. The plant's operations help protect the local watershed and downstream aquatic ecosystems from untreated wastewater pollution.

The Tczow plant discharges into a local watercourse that is part of the Vistula River basin. The Vistula flows northward through Poland and empties into the Baltic Sea via the Gulf of Gdańsk. The surrounding area is predominantly agricultural, and the plant helps reduce nutrient and organic pollution that could otherwise contribute to eutrophication in the Baltic Sea, a sensitive marine environment.
