Oczyszczalnia Klecie - Secondary Wastewater Treatment Plant in Gładyszów, Poland

Oczyszczalnia Klecie is a wastewater treatment plant located in Gładyszów, within the gmina Uście Gorlickie in województwo małopolskie, Poland. The plant serves a population of 782 and is classified as a secondary treatment facility, providing biological treatment to reduce organic pollutants and suspended solids before discharge. The plant operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations with a population equivalent (PE) between 2,000 and 15,000. With a population served of 782, the plant falls below this threshold, but Polish regulations mandate appropriate treatment for all discharges to protect water quality. The designed capacity of 2583.00 m³/day indicates the plant's potential to handle higher flows, while the actual discharge volume is 111.50 m³/day. The treated effluent from Oczyszczalnia Klecie is discharged into local watercourses that eventually drain into the Wisłoka River, a tributary of the Vistula River, which flows into the Baltic Sea. The plant plays a key role in protecting the local watershed from untreated sewage, supporting aquatic life and downstream water quality in the Vistula basin.

The plant discharges into small streams that feed the Wisłoka River, part of the Vistula River basin, which ultimately reaches the Baltic Sea. The region is characterized by the Carpathian foothills, with sensitive aquatic ecosystems that benefit from reduced nutrient and organic loads. The treatment helps prevent eutrophication and maintains biodiversity in the downstream rivers and coastal waters.
