Zaganskie Wodociagi i Kanalizacje Sp z oo - Żagań Wastewater Treatment Plant

Zaganskie Wodociagi i Kanalizacje Sp z oo is a wastewater treatment plant located in Żagań, in the Lubusz Voivodeship of western Poland. The facility serves a population of around 20,796, classifying it as a medium-sized agglomeration under EU regulations. The plant is situated inland, away from coastal areas, and its operations are integral to the local sanitation infrastructure. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations of this size are required to provide secondary treatment as a minimum. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas. The plant's compliance with these standards ensures that treated effluent meets regulatory quality requirements before discharge. The treated wastewater is discharged into local watercourses that eventually drain into the Oder River basin, which flows northward to the Baltic Sea. The plant plays a key role in protecting the region's water resources and downstream ecosystems from pollution, supporting aquatic life and water quality in the Oder catchment.

The plant discharges into the Oder River basin, which flows through western Poland and into the Baltic Sea. The Oder is a major European river supporting diverse aquatic habitats and migratory fish species. The plant's treatment processes help maintain water quality in this ecologically significant watershed, reducing nutrient loads that could otherwise contribute to eutrophication in the Baltic Sea.
