Grodek nad Dunajcem Wastewater Treatment Plant - Advanced Treatment in Małopolskie

Grodek nad Dunajcem wastewater treatment plant is located in the village of Gródek nad Dunajcem, within the powiat nowosądecki of województwo małopolskie, Poland. The facility serves a population of 749 and has a designed capacity of 3000 m³/day, with an average discharge volume of 106.80 m³/day. The plant employs advanced treatment processes, meeting the stringent requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC). For small agglomerations under 2000 population equivalent, the directive requires appropriate treatment, and Poland's national regulations ensure compliance with effluent standards for sensitive areas. The treated wastewater is discharged into the local watershed, which drains into the Dunajec River, a tributary of the Vistula River. The Vistula flows northward through Poland into the Baltic Sea. The plant plays a key role in protecting the Dunajec River and downstream ecosystems from nutrient pollution.

The plant discharges into the Dunajec River, a major tributary of the Vistula River, which ultimately flows into the Baltic Sea. The Dunajec River supports diverse aquatic life and is an important corridor for migratory fish. Advanced treatment at this plant helps reduce nutrient loading, protecting water quality in the Vistula basin and the Baltic Sea from eutrophication.
