Lubin Wastewater Treatment Plant, Miroszowice | Lower Silesian Voivodeship, Poland

The Lubin wastewater treatment plant is located in Miroszowice, a village in the Lubin commune of Lower Silesian Voivodeship, Poland. It serves a population of approximately 69,904 people, placing it in the medium-to-large agglomeration category under EU classification. The plant is part of the municipal wastewater infrastructure for the Lubin area, which includes both urban and industrial contributions. As a Polish facility serving over 10,000 population equivalent, the Lubin plant is subject to the EU Urban Waste Water Treatment Directive 91/271/EEC. This directive requires secondary treatment (biological treatment) as a minimum standard for such agglomerations. The regulatory framework ensures compliance with national and EU standards for effluent quality. The treated wastewater from the Lubin plant is discharged into local watercourses that ultimately drain into the Oder River basin. The Oder River flows northward through western Poland and empties into the Baltic Sea via the Szczecin Lagoon. The plant plays a key role in protecting the region's surface waters from nutrient and organic pollution, supporting aquatic life and downstream ecosystems.

The Lubin plant discharges into the Oder River basin, which flows through southwestern Poland and into the Baltic Sea via the Szczecin Lagoon. The Oder is a major European river supporting diverse aquatic habitats and migratory fish species. The plant's operations help reduce nutrient loads that could otherwise contribute to eutrophication in the Baltic Sea, a sensitive marine environment.
