Chojna Wastewater Treatment Plant | Chojna, zachodniopomorskie, Poland

The Chojna wastewater treatment plant is located in the town of Chojna, in the zachodniopomorskie province of northwestern Poland. The facility serves a population of approximately 7,584 people, classifying it as a small to medium agglomeration under Polish and EU regulations. The plant is situated near the border with Germany, in a region characterized by agricultural and forested landscapes. As a Polish wastewater treatment facility serving a population of this scale, the plant is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC). This directive requires secondary treatment for discharges to freshwater and estuaries from agglomerations of this size. The plant's operational details, including specific treatment processes and capacity, are managed by the local municipal authority to ensure compliance with national and EU standards. The treated effluent is discharged into local watercourses that ultimately drain into the Odra River basin, which flows into the Baltic Sea. The plant plays a key role in protecting the region's water quality, supporting aquatic life in the downstream rivers and contributing to the ecological health of the Baltic Sea coastal environment.

The Chojna plant discharges into the Odra River basin, which flows northward to the Szczecin Lagoon and then into the Baltic Sea. This watershed supports diverse aquatic ecosystems, including fish spawning grounds and migratory bird habitats. The region's agricultural runoff and small industrial inputs make effective wastewater treatment critical for maintaining water quality in the sensitive Baltic Sea coastal zone.
