Bialy Bor Wastewater Treatment Plant, Borne Sulinowo, Poland

Bialy Bor is a wastewater treatment plant located in Borne Sulinowo, within the zachodniopomorskie province of Poland. The plant serves a population of 3,243, classifying it as a small agglomeration under Polish and EU regulations. It operates as a municipal facility, providing essential sanitation services to the local community. The plant employs secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The designed capacity of 4,127 m³/day indicates the plant's ability to handle peak flows, while the current discharge volume of 462.40 m³/day suggests operational capacity well within design limits. As a Polish facility, it operates under the national water law and environmental permits issued by regional authorities. The treated effluent is discharged into local water bodies, likely tributaries of the Parsęta River or the Gwda River, which flow into the Baltic Sea. The plant plays a key role in protecting the region's surface waters from nutrient pollution, supporting aquatic ecosystems and downstream water quality in the Baltic Sea catchment.

The plant discharges into the local watershed, which is part of the Baltic Sea basin. The receiving waters eventually drain into the Baltic Sea, a semi-enclosed sea sensitive to eutrophication from nutrient inputs. The region's rivers and lakes support diverse aquatic life, including fish species such as pike and perch, and provide habitat for migratory birds. Effective wastewater treatment is critical to reducing phosphorus and nitrogen loads that can cause algal blooms and oxygen depletion in the Baltic.
