Urzedow Wastewater Treatment Plant, Mikuszewskie, Poland

The Urzedow wastewater treatment plant is located in Mikuszewskie, within the gmina Urzędów in powiat kraśnicki, województwo lubelskie, Poland. It serves a small agglomeration of 649 people, reflecting the rural character of the region. The plant is part of Poland's municipal wastewater infrastructure, which is regulated under the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant operates with secondary treatment, which is the standard requirement under the EU directive for agglomerations of this size. Its designed capacity is 1793 m³/day, with an actual discharge volume of 92.54 m³/day, indicating that the plant operates well below its capacity. This suggests that the infrastructure is sized to accommodate future growth or seasonal variations in flow. The treated effluent is discharged into local watercourses that drain into the Vistula River basin, ultimately reaching the Baltic Sea. The plant plays a key role in protecting the region's surface waters from nutrient pollution, supporting aquatic life and downstream ecosystems in the Vistula delta and the Baltic Sea.

The plant discharges into local streams that are part of the Vistula River basin, which flows northward into the Baltic Sea. The Vistula is Poland's largest river and supports diverse aquatic habitats, including important spawning grounds for migratory fish. The Baltic Sea is a semi-enclosed sea sensitive to eutrophication from nutrient inputs, making effective wastewater treatment crucial for reducing nitrogen and phosphorus loads.
