Swornegacie Wastewater Treatment Plant - Pomerania, Poland

The Swornegacie wastewater treatment plant is located in the village of Swornegacie, in the Chojnice district of Pomerania, Poland. It serves a small population of 640 residents, reflecting its role in a rural community. The plant is part of Poland's municipal wastewater infrastructure, which is regulated under national and EU frameworks. The facility provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 4,000 m³/day, the plant operates at a low utilization rate, treating 91.25 m³/day. This scale aligns with EU Urban Waste Water Treatment Directive requirements for small agglomerations, which mandate secondary treatment for inland areas. The treated effluent is discharged into local watercourses that ultimately drain into the Baltic Sea via the Vistula River basin. The plant helps protect the region's lakes and rivers from nutrient pollution, supporting aquatic ecosystems in the Pomeranian lake district. Its operation contributes to the ecological health of the Baltic Sea catchment area.

The plant discharges into local streams that feed into the Brda River, a tributary of the Vistula River, which flows into the Baltic Sea. The surrounding area features numerous lakes and wetlands that are ecologically sensitive, supporting diverse aquatic life and migratory birds. The plant's secondary treatment reduces organic load and nutrients, helping to prevent eutrophication in downstream water bodies.
