Psary Wastewater Treatment Plant - Secondary Treatment in Województwo Śląskie, Poland

The Psary wastewater treatment plant is located in the village of Psary, within the gmina Woźniki in województwo śląskie, Poland. It serves a small population of 972 residents, reflecting its role as a local municipal facility in a rural area of southern Poland. The plant provides secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The designed capacity of 2358 m³/day indicates the plant's potential to handle higher loads, while the current discharge volume of 138.59 m³/day shows it operates well below capacity. The treated effluent is discharged into local watercourses that ultimately drain into the Oder River basin, which flows northward to the Baltic Sea. The plant's operation helps protect the local aquatic environment and downstream ecosystems from untreated wastewater pollution.

The plant discharges into small streams within the Oder River basin, which flows through southwestern Poland and into the Baltic Sea via the Szczecin Lagoon. The local watershed supports diverse aquatic life and is part of a region with agricultural and forested landscapes. Proper treatment is essential to prevent nutrient enrichment and maintain water quality in this ecologically sensitive area.
