Stanin Wastewater Treatment Plant, Stanisławów, Lubelskie Voivodeship

The Stanin wastewater treatment plant is located in Stanisławów, within the gmina Stanin, powiat łukowski, in the Lubelskie Voivodeship of eastern Poland. It serves a small community of 662 residents, 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 facility provides secondary treatment, which is the standard level required by the EU directive for agglomerations with a population equivalent (PE) between 2,000 and 10,000. Although the population served here is below that threshold, the plant's design capacity of 1,266 m³/day suggests it is sized to accommodate future growth or seasonal variations. The discharge volume is reported as 94.39 m³/day, indicating a utilization rate well below capacity. The treated effluent is discharged into local surface waters, likely a small stream or river within the Wieprz or Vistula basin. The plant's operation contributes to protecting the local environment and downstream water quality, supporting the ecological health of the region's rivers and ultimately the Baltic Sea.

The Stanin plant discharges into a local watercourse that is part of the Vistula River basin, which drains into the Baltic Sea. The region is characterized by agricultural land use and small water bodies that support diverse aquatic life. The plant's secondary treatment helps reduce nutrient loads, protecting downstream ecosystems from eutrophication and maintaining water quality for biodiversity.
