Borne Sulinowo Wastewater Treatment Plant | West Pomeranian Voivodeship, Poland

The Borne Sulinowo wastewater treatment plant is located in the town of Borne Sulinowo, within the West Pomeranian Voivodeship of northwestern Poland. This facility serves a population of about 7,962 residents, classifying it as a small to medium agglomeration under Polish and EU regulations. As a plant operating under the EU Urban Waste Water Treatment Directive (91/271/EEC), it is required to provide secondary treatment as a minimum standard for agglomerations of this size. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas. The regulatory framework ensures compliance with national and EU standards. The treated effluent from the plant is discharged into local watercourses that ultimately drain into the Baltic Sea via the Parsęta River basin or nearby coastal rivers. The region is characterized by post-glacial landscapes with numerous lakes and forests, and the plant plays a key role in protecting the local aquatic environment from nutrient pollution and other contaminants.

The plant discharges into the Parsęta River basin, which flows northward into the Baltic Sea. The Baltic Sea is a semi-enclosed brackish sea sensitive to eutrophication from nutrient inputs. The local watershed includes several lakes and wetlands that support diverse aquatic life and migratory bird populations. Effective wastewater treatment is critical to reducing nitrogen and phosphorus loads that can cause algal blooms and oxygen depletion in downstream waters.
