Zduny Wastewater Treatment Plant | Serving Zduny, Wielkopolskie, Poland

The Zduny wastewater treatment plant is located in the town of Zduny, in the Wielkopolskie region of Poland. Serving a population equivalent of 16,362, the facility is part of the municipal wastewater infrastructure for this medium-sized agglomeration in west-central Poland. As a Polish plant, Zduny operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations between 10,000 and 150,000 population equivalent. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas. Poland has transposed these requirements into national law, and plants of this scale are typically subject to regular monitoring and permitting by regional water authorities. The treated effluent from the Zduny plant is discharged into local watercourses that ultimately drain into the Oder River basin, which flows northward to the Baltic Sea. The Oder basin supports diverse aquatic ecosystems and is an important migratory corridor for fish species. The plant's operation helps protect downstream water quality in this ecologically significant region.
