Kazimierz Dolny Wastewater Treatment Plant, Wólka Dąbrowska, Poland

The Kazimierz Dolny wastewater treatment plant is located in Lipka, near Wólka Dąbrowska, in the powiat lipski region of województwo mazowieckie, Poland. It serves a population of 2,591 and has a designed capacity of 8,000 m³/day, with a current discharge volume of 369.44 m³/day. The plant provides secondary treatment, which is the standard level required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. As a Polish facility, the plant operates under national regulations that transpose the EU directive. For a population equivalent of 2,591, secondary treatment is appropriate, and the plant's capacity suggests it can accommodate future growth. The discharge volume indicates current utilization is well below capacity, allowing for operational flexibility. The plant discharges treated wastewater into local watercourses that ultimately drain into the Vistula River basin. The Vistula flows northward through Poland into the Baltic Sea. The surrounding area is rural and agricultural, so the plant plays a key role in protecting local streams and groundwater from nutrient pollution, supporting aquatic life in the Vistula catchment.

The Kazimierz Dolny plant discharges into the Vistula River basin, which is Poland's largest river system and flows into the Baltic Sea. The Vistula supports diverse aquatic ecosystems and is an important migratory corridor for fish. The plant's secondary treatment helps reduce organic load and nutrients, mitigating eutrophication risks in downstream water bodies and the Baltic Sea.
