Dobiegniew Wastewater Treatment Plant, Lubusz Voivodeship, Poland

The Dobiegniew wastewater treatment plant is located in the town of Dobiegniew, within the Lubusz Voivodeship of western Poland. It serves a population of 2,564 residents, classifying it as a small agglomeration under Polish and EU regulations. The plant is situated on Nowomłyńska Street, near the local water infrastructure. The facility provides secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The plant has a designed capacity of 7,400 m³/day and currently discharges an average of 365.59 m³/day of treated wastewater. As a secondary treatment plant, it removes organic matter and suspended solids, meeting the directive's requirements for inland discharges. The treated effluent from Dobiegniew is discharged into a local watercourse, which ultimately drains into the Noteć River basin and then to the Warta River, a major tributary of the Oder River. The Oder flows into the Baltic Sea via the Szczecin Lagoon. The plant plays a key role in protecting the local aquatic environment and downstream ecosystems from untreated pollution.

The Dobiegniew plant discharges into a small watercourse that feeds into the Noteć River, part of the Warta-Oder river system. This basin eventually reaches the Baltic Sea through the Szczecin Lagoon. The region supports diverse aquatic life, including fish species such as pike and perch, and the wetlands along the Noteć provide important habitats for migratory birds. Proper wastewater treatment is essential to prevent nutrient loading and maintain water quality in this sensitive riverine and coastal ecosystem.
