Rudki Wastewater Treatment Plant, Rudki, Poland | Secondary Treatment, Vistula Basin

Rudki wastewater treatment plant is located in the village of Rudki, within the gmina Nowa Słupia in województwo świętokrzyskie, Poland. The plant serves a population of 1,395 and is 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. With a designed capacity of 4,900 m³/day and an actual discharge volume of 198.91 m³/day, the plant operates well below its capacity, indicating room for future growth. The treated effluent is discharged into local watercourses that eventually drain into the Vistula River basin, which flows northward to the Baltic Sea. The plant plays a key role in protecting the region's water quality and supporting the ecological health of downstream aquatic environments.

The plant discharges into local streams that are part of the Vistula River basin, Poland's largest river system. The Vistula flows through central Poland and empties into the Baltic Sea near Gdańsk. The watershed supports diverse aquatic life and is an important ecological corridor for migratory fish species. The plant's secondary treatment helps reduce nutrient loads and organic pollution, contributing to the overall health of the Baltic Sea ecosystem.
