Gorzyce Wastewater Treatment Plant - Advanced Treatment in Podkarpackie, Poland

The Gorzyce wastewater treatment plant is located in the village of Gorzyce, within the Podkarpackie Voivodeship of southeastern Poland. It serves a population of approximately 3,841 residents, classifying it as a small agglomeration under Polish and EU regulations. The plant employs advanced treatment processes, which go beyond the EU Urban Waste Water Treatment Directive's minimum requirement of secondary treatment for agglomerations of this size. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive water bodies. The plant has a designed capacity of 9,999 m³/day, with an actual discharge volume of 547.67 thousand m³ per year, indicating ample capacity for current loads. The treated effluent is discharged into local surface waters, which ultimately drain into the Vistula River basin and then to the Baltic Sea. This makes the plant's advanced treatment important for reducing nutrient loads that could contribute to eutrophication in the Baltic Sea, a region designated as sensitive under the EU Urban Waste Water Treatment Directive.

The plant's discharge enters local streams that flow into the Vistula River, Poland's largest river, which empties into the Baltic Sea. The Baltic Sea is a semi-enclosed sea highly sensitive to nutrient pollution, leading to algal blooms and oxygen depletion. Advanced treatment at Gorzyce helps reduce nitrogen and phosphorus loads, supporting the health of downstream aquatic ecosystems and the Baltic's ecological balance.
