Lubin Wastewater Treatment Plant, Lubiń, Poland

The Lubin wastewater treatment plant is located in Lubiń, a village in the Wielkopolskie Voivodeship of Poland. It serves a small population of 20 people, reflecting its role in a rural community. The plant is situated in the Kościan County, within the broader region of Greater Poland. The plant provides secondary treatment, which is the standard biological treatment required under Polish regulations implementing the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations with a population equivalent below 2,000, secondary treatment is typically sufficient. The plant's design capacity is 100 m³/day, and it currently discharges 2.85 m³/day of treated wastewater. The treated effluent is likely discharged into a local watercourse, contributing to the Obra River basin, which eventually flows into the Warta River and then the Oder River. The Oder River discharges into the Baltic Sea. The plant's operation helps protect local streams and groundwater from untreated sewage, supporting aquatic life in the region's agricultural landscape.

The Lubin plant discharges into a local watercourse that is part of the Obra River basin, a tributary of the Warta River, which flows into the Oder River and ultimately the Baltic Sea. The region is characterized by agricultural land use, and the plant helps prevent nutrient pollution that could lead to eutrophication in downstream waters. The Oder River estuary is ecologically sensitive, supporting diverse fish and bird species.
