Leczyca Wastewater Treatment Plant, Gliznowo, Poland

The Leczyca wastewater treatment plant is located in Gliznowo, within the gmina Lubień Kujawski in województwo kujawsko-pomorskie, Poland. It serves a population of approximately 11,560, classifying it as a medium-sized agglomeration under Polish and EU regulations. As a Polish facility, the plant is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas. Compliance with national standards ensures appropriate treatment for its scale. The treated effluent from the plant is discharged into local watercourses that ultimately drain into the Vistula River basin, which flows into the Baltic Sea. The plant plays a key role in protecting the region's water quality, supporting aquatic ecosystems and downstream communities.

The Leczyca plant discharges into the Vistula River basin, which flows northward through Poland and empties into the Baltic Sea. The watershed supports diverse aquatic life and is an important ecological corridor. The Baltic Sea is a sensitive marine environment, and nutrient removal from wastewater is critical to prevent eutrophication. The plant's operation helps maintain water quality in the region.
