Sliwice Wastewater Treatment Plant, Śliwice, Poland

The Sliwice wastewater treatment plant is located in the village of Śliwice, in the Kuyavian-Pomeranian Voivodeship of Poland. It serves a population of approximately 3,918 people, classifying it as a small agglomeration under Polish regulations. The plant is situated inland, away from coastal areas, and treats municipal wastewater from the local community. The plant provides secondary treatment, which is the minimum standard required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The designed capacity of 4,555 cubic meters per day indicates the plant's ability to handle peak flows, while the current discharge volume of 558.65 cubic meters per day suggests operational headroom. As a Polish facility, it operates under the national water law and is subject to permits issued by the Regional Water Management Board. The treated effluent is discharged into a local watercourse, likely a small river or stream within the Brda or Vistula basin, eventually reaching the Baltic Sea. The plant plays a crucial role in protecting local water quality and the downstream aquatic ecosystem, which supports diverse flora and fauna in the Pomeranian region.

The plant discharges into a local watercourse that is part of the Vistula River basin, which ultimately flows into the Baltic Sea. The surrounding area features forests and lakes characteristic of the Tuchola Forest region, an ecologically sensitive area that supports diverse aquatic life and migratory bird species. Proper wastewater treatment is essential to prevent nutrient enrichment and maintain the ecological balance of these waters.
