Skorcz Wastewater Treatment Plant, Skórcz, Poland

The Skorcz wastewater treatment plant is located in Skórcz, a town in the Starogard County of Pomeranian Voivodeship, Poland. It serves a population of approximately 5,965 people, classifying it as a small agglomeration under Polish and EU regulations. The plant provides secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for discharges into freshwater bodies from agglomerations of this size. The plant has a designed capacity of 9,908 m³ per day, with an average daily discharge of 850.52 m³, indicating significant reserve capacity. The treated effluent is discharged into local watercourses that ultimately drain into the Vistula River basin and then into the Baltic Sea. The plant plays a key role in protecting the region's surface waters from nutrient pollution, supporting aquatic life and downstream ecological health.

The plant discharges into the Wierzyca River, a tributary of the Vistula, which flows into the Baltic Sea. This region is part of the Vistula Lagoon catchment, an area sensitive to eutrophication from nitrogen and phosphorus. The secondary treatment helps reduce organic load and nutrients, mitigating impacts on downstream ecosystems and the Baltic Sea's fragile marine environment.
