Debrzno Wies Wastewater Treatment Plant - Advanced Treatment in Debrzno-Wieś, Poland

Debrzno Wies is an advanced wastewater treatment plant located in Debrzno-Wieś, within the gmina Lipka, powiat złotowski, województwo wielkopolskie, Poland. The plant serves a population of approximately 6,572 people, classifying it as a small to medium agglomeration under EU standards. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 8,745 m³/day and a discharge volume of 937.06 m³/day, the facility operates well within its capacity. As a Polish plant, it complies with the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates appropriate treatment levels based on population equivalents and receiving water sensitivity. The treated effluent is discharged into local water bodies that ultimately drain into the Baltic Sea via the Vistula or Oder river basins. The region's watershed supports diverse aquatic life and contributes to the ecological health of the Baltic Sea, a semi-enclosed sea sensitive to nutrient pollution.

The plant discharges into local streams that feed into the Noteć River, a tributary of the Warta River, which flows into the Oder River and eventually the Baltic Sea. The Baltic Sea is a brackish, semi-enclosed sea with limited water exchange, making it sensitive to nutrient inputs that can cause eutrophication. The advanced treatment at Debrzno Wies helps reduce nutrient loads, protecting downstream aquatic ecosystems.
