Gostun Wastewater Treatment Plant, Gostuń | Poland

The Gostun wastewater treatment plant is located in Gostuń, a village in the Wielkopolskie Voivodeship of Poland. It serves a population of 1,388 and operates under Polish regulations implementing the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant provides secondary treatment, which is the standard requirement for agglomerations of this size under the directive. With a design capacity of 3,800 m³/day and an average daily discharge of 197.91 m³/day, the plant operates well below its capacity, indicating room for future growth. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into local watercourses that eventually drain into the Warta River basin, part of the Oder River system flowing into the Baltic Sea. The plant plays a key role in protecting local streams and groundwater from untreated sewage, supporting the ecological health of the region's waterways.

The plant discharges into the Warta River basin, which flows into the Oder River and ultimately the Baltic Sea. The local watershed supports diverse aquatic life and is part of a network of rivers and lakes in the Wielkopolska region. The plant's secondary treatment helps reduce nutrient loads, protecting downstream ecosystems from eutrophication.
