Przodkowo Wastewater Treatment Plant, Kczewo | Pomeranian Region, Poland

The Przodkowo wastewater treatment plant is located in Kczewo, within the gmina of Przodkowo in the Kartuzy County of Poland's Pomeranian Voivodeship. This facility serves a population of approximately 5,242 people, classifying it as a small to medium agglomeration under Polish and EU regulations. The plant provides secondary treatment, which is the standard requirement under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size discharging into freshwater. The designed capacity of 7,567 m³/day indicates significant headroom for future growth. Poland's water and wastewater sector is regulated by the National Water Management Authority (PGW Wody Polskie), which issues permits and monitors compliance. The treated effluent from Przodkowo likely discharges into a local watercourse that flows toward the Baltic Sea via the region's river network. The Pomeranian region features numerous lakes and rivers that ultimately drain into the Gulf of Gdańsk. Protecting these waters from nutrient pollution is critical for the Baltic Sea's ecological health, which suffers from eutrophication due to excessive nitrogen and phosphorus loads.

The plant's discharge enters a local stream that is part of the broader drainage network feeding the Baltic Sea. The Baltic Sea is a semi-enclosed brackish sea highly sensitive to nutrient inputs, where secondary treatment helps reduce organic load but may not fully address nutrient removal. The surrounding area includes agricultural lands and small settlements, contributing diffuse pollution that the plant's treatment helps mitigate.
