Budzyn Wastewater Treatment Plant, Radzyny, Poland - Secondary Treatment Facility

Budzyn wastewater treatment plant is located in Radzyny, within the Wielkopolskie province of Poland. It serves a population of approximately 3,193 people, classifying it as a small agglomeration under Polish and EU regulations. The plant operates secondary treatment, which is the standard for communities of this size in the region. The plant has a designed capacity of 7,020 m³/day and currently discharges an average of 455.27 m³/day of treated wastewater. As a Polish facility, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations above 2,000 population equivalent. The plant's performance is regulated by Polish water authorities to ensure compliance with national and EU standards. The treated effluent is discharged into local watercourses that eventually drain into the Warta River basin, a major tributary of the Oder River. The Oder flows into the Baltic Sea, making the plant's operations relevant to the ecological health of the Baltic marine environment. The surrounding region features agricultural landscapes and small water bodies that benefit from proper wastewater management.

The plant's discharge enters local streams within the Warta River catchment, which flows into the Oder River and ultimately reaches the Baltic Sea. The Baltic Sea is a semi-enclosed brackish sea sensitive to nutrient pollution, making effective nutrient removal at treatment plants critical. The surrounding Wielkopolskie region has a mix of agricultural and natural areas, where treated wastewater helps maintain water quality in local rivers and supports aquatic biodiversity.
