Przedborz Wastewater Treatment Plant, Przedbórz | Advanced Treatment, Small Population

The Przedborz wastewater treatment plant is located in Przedbórz, a town in the Łódź Voivodeship of central Poland. This facility serves a small population of 560 residents, reflecting its role in a rural or small urban community. The plant is situated inland, far from coastal areas, and its operations are part of Poland's municipal wastewater infrastructure. The plant provides advanced treatment, which goes beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations under 10,000 population equivalent. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive water bodies. The plant's designed capacity of 4700 m³/day indicates it can handle peak flows, while the actual discharge volume of 79.85 m³/day suggests low current utilization. The treated effluent is discharged into local waterways that ultimately drain into the Pilica River, a tributary of the Vistula River, which flows into the Baltic Sea. The plant's advanced treatment helps protect the Pilica River ecosystem, which supports diverse aquatic life and is an important corridor for migratory fish. The facility contributes to maintaining water quality in the region's surface waters.

The plant discharges into the Pilica River basin, which flows northward to join the Vistula River near Warsaw. The Vistula then empties into the Baltic Sea via the Gdańsk Bay. The Pilica River supports a variety of fish species and is ecologically sensitive to nutrient pollution. Advanced treatment at this plant helps reduce the risk of eutrophication in downstream waters, including the Baltic Sea, which is vulnerable to algal blooms from excess nitrogen and phosphorus.
