Leczyca Wastewater Treatment Plant, Łęczyca, Poland | EU UWWTD Compliance

The Leczyca wastewater treatment plant is located in Łęczyca, a town in the Greater Poland Voivodeship of Poland. The facility serves a population of around 31,532, placing it within the medium agglomeration category under EU classification. As a Polish plant, it operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations of this size. The plant's treatment processes and capacity are managed to meet national and EU standards for effluent quality. The treated wastewater is discharged into local watercourses that ultimately drain into the Warta River basin, a major tributary of the Oder River. This contributes to the protection of the Baltic Sea ecosystem, as the Oder flows into the Baltic. The plant plays a key role in maintaining water quality in the region's rivers and downstream environments.

The Leczyca plant discharges into the Warta River basin, which flows into the Oder River and eventually reaches the Baltic Sea. This watershed supports diverse aquatic life and is important for regional biodiversity. The plant's operations help reduce nutrient loads and pollutants that could otherwise impact downstream ecosystems, including the sensitive Baltic Sea environment.
