Kapusciska Wastewater Treatment Plant, Bydgoszcz | Large-Scale Municipal Facility

Kapusciska is a major wastewater treatment plant located in Bydgoszcz, Poland, in the Kuyavian-Pomeranian Voivodeship. It serves a population of approximately 331,264 people, making it a large agglomeration under EU classification. The plant is situated in the Kapusciska district of Bydgoszcz. As a facility serving over 150,000 population equivalent, Kapusciska is subject to the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires tertiary treatment for discharges into sensitive areas. The plant's treatment processes are designed to meet these stringent standards, ensuring effective removal of nutrients and pollutants before discharge. The treated effluent from Kapusciska is discharged into the Brda River, a tributary of the Vistula River, which flows into the Baltic Sea. This discharge contributes to the protection of the Vistula basin and the Baltic Sea ecosystem, supporting water quality and aquatic life in the region.

The Kapusciska plant discharges into the Brda River, which flows into the Vistula River and ultimately reaches the Baltic Sea. The Baltic Sea is a semi-enclosed sea with limited water exchange, making it sensitive to nutrient pollution. The plant's advanced treatment helps reduce eutrophication risks in the downstream water bodies, supporting the ecological health of the Vistula basin and the Baltic coastal environment.
