The Chmielno wastewater treatment plant is located in Kożyczkowo, a village in the Pomeranian Voivodeship of northern Poland. It serves a population of approximately 2,440 residents, operating as a municipal facility within the Gmina Chmielno administrative district. The plant employs advanced treatment processes, meeting the stringent requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC) for sensitive areas. With a designed capacity of 10,000 m³/day and an actual discharge volume of 347.91 thousand m³/year, the facility is operating well below its capacity, indicating room for future growth or seasonal variations. Treated effluent is discharged into local watercourses that ultimately drain into the Baltic Sea via the Radunia River and the Vistula Lagoon system. The plant plays a key role in protecting the region's lakes and rivers, which support diverse aquatic life and are important for recreation and tourism in the Kashubian Lake District.
Environmental context
The plant discharges into the Radunia River basin, which flows into the Motława River and then the Vistula Lagoon, a coastal lagoon of the Baltic Sea. This watershed supports sensitive ecosystems, including wetlands and fish spawning grounds. The advanced treatment helps reduce nutrient loading, mitigating eutrophication risks in the Baltic Sea, a region already impacted by agricultural runoff and urban discharges.
