The Lebork wastewater treatment plant is located in Lębork, a town in the Pomeranian Voivodeship of northern Poland. Serving a population of approximately 40,222, the facility is part of the municipal wastewater infrastructure for the region. The plant is situated inland, more than 50 km from the Baltic Sea coast. As a medium-sized agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD) 91/271/EEC, the plant is required to provide secondary treatment (biological treatment) as a minimum. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day), indicating a facility sized to handle the local wastewater load. The treated effluent from the plant is discharged into a local watercourse, which eventually drains into the Baltic Sea via the Łeba River or other nearby rivers. The Baltic Sea is a brackish inland sea with sensitive ecosystems, and nutrient removal is a key concern for plants in the region to prevent eutrophication. The plant's operation contributes to protecting the local watershed and downstream marine environment.
Environmental context
The Lebork plant discharges into a local river system that flows into the Baltic Sea, a semi-enclosed sea with limited water exchange and high sensitivity to nutrient pollution. The region's watershed supports diverse aquatic life and is an important area for migratory birds. Effective wastewater treatment is critical to reducing nitrogen and phosphorus loads that can cause algal blooms and hypoxia in coastal waters.
Frequently asked questions
The Lebork wastewater treatment plant is located in Lębork, a town in the Pomeranian Voivodeship of northern Poland. The facility is situated inland, more than 50 km from the Baltic Sea coast.
The Lebork wastewater treatment plant serves a population equivalent of approximately 40,222 people, classifying it as a medium-sized agglomeration under EU regulations.
The treated effluent from the Lebork plant is discharged into a local watercourse, which eventually flows into the Baltic Sea via rivers such as the Łeba River. The discharge is regulated under Polish and EU water quality standards.
As a Polish facility, the Lebork plant operates under the EU Urban Waste Water Treatment Directive (UWWTD) 91/271/EEC, which requires secondary treatment for agglomerations over 10,000 population equivalent. Poland's national regulations implement this directive through permits issued by regional water authorities.
For medium-sized agglomerations like Lebork (40,222 PE), the EU UWWTD mandates secondary treatment (biological treatment). If the receiving waters are sensitive to eutrophication, additional nutrient removal (tertiary treatment) may be required. Many Polish plants in the Baltic Sea catchment area have upgraded to include nitrogen and phosphorus removal.
