Truskolasy Wastewater Treatment Plant, Świbie, Poland

Truskolasy is a secondary wastewater treatment plant located near Świbie in the Silesian Voivodeship of southern Poland. The facility serves a population of 1,880 and is part of the municipal infrastructure for the local community in the Gliwice County area. As a secondary treatment plant, Truskolasy meets the standard requirements under Polish regulations, which transpose the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations with a population equivalent between 2,000 and 10,000, secondary treatment is the minimum required level. The plant's designed capacity of 4,933 m³/day indicates it is sized to handle peak flows, while current discharge volume is 268.06 m³/day. The treated effluent from Truskolasy is discharged into local watercourses that ultimately drain into the Oder River basin, which flows northward to the Baltic Sea. The plant plays a key role in protecting the region's surface waters from untreated sewage, supporting aquatic life and downstream water quality in the Oder catchment.

The plant discharges into local streams that are part of the Oder River basin. The Oder flows through Poland and Germany before reaching the Baltic Sea, supporting diverse aquatic ecosystems. The region's water bodies are sensitive to nutrient pollution, and secondary treatment helps reduce organic load and protect downstream habitats.
