Łęknica Wastewater Treatment Plant - Secondary Treatment for 2,769 People in Lubuskie, Poland

The Łęknica wastewater treatment plant is located in the town of Łęknica, in województwo lubuskie, western Poland, near the border with Germany. It serves a population of 2,769, classifying it as a small agglomeration under Polish and EU regulations. The plant provides secondary treatment, which is the minimum required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Its designed capacity is 3,967 m³/day, and it currently discharges 394.82 m³/day of treated wastewater. The plant operates under Polish environmental law, which implements EU directives. Treated effluent from the plant is discharged into a local watercourse that ultimately drains into the Lusatian Neisse River, a tributary of the Oder River. The Oder flows into the Baltic Sea via the Szczecin Lagoon. The plant plays a key role in protecting the local watershed and downstream aquatic ecosystems from untreated pollution.

The plant discharges into a local stream that flows into the Lusatian Neisse River, which forms the border between Poland and Germany. The Lusatian Neisse joins the Oder River, which empties into the Baltic Sea through the Szczecin Lagoon. The Oder basin supports diverse aquatic life and is an important migratory corridor for fish. The plant's secondary treatment helps reduce nutrient loads that could otherwise contribute to eutrophication in the Baltic Sea.
