Lipusz Wastewater Treatment Plant - Secondary Treatment for 1,370 Residents in Pomeranian Voivodeship

The Lipusz wastewater treatment plant is located in the town of Lipusz, in the Kościerzyna County of Pomeranian Voivodeship, Poland. It serves a population of approximately 1,370 residents, classifying it as a small agglomeration under Polish and EU regulations. The plant provides secondary treatment, which is the minimum standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for discharges into freshwater and estuaries from agglomerations of this size. The designed capacity is 3,000 m³/day, with a reported discharge volume of 195.34 m³/day, indicating ample reserve capacity. The treated effluent is discharged into local watercourses that eventually drain into the Baltic Sea via the Vistula River basin. The plant plays a key role in protecting the region's lakes and rivers from nutrient pollution, supporting aquatic biodiversity and recreational water quality.

The plant discharges into local streams that are part of the Vistula River basin, which flows northward into the Baltic Sea. The region features numerous glacial lakes and sensitive freshwater ecosystems. Effective nutrient removal at this plant helps prevent eutrophication in downstream water bodies, supporting diverse aquatic life and maintaining water quality for local communities.
