Komorowo Wastewater Treatment Plant, Kębłowo-Kolonia, Poland

Komorowo is a wastewater treatment plant located in Kębłowo-Kolonia, within the Wolsztyn commune of województwo wielkopolskie, Poland. The facility serves a population of approximately 34,233 people, placing it in the medium agglomeration category under European Union classification. As a Polish plant, Komorowo operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations of this size. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas. The plant's treatment processes and capacity are managed to comply with national regulations derived from this framework. The treated effluent from Komorowo is discharged into local watercourses that ultimately drain into the Oder River basin, flowing northward to the Baltic Sea. The plant plays a key role in protecting the region's surface waters from nutrient pollution and organic load, supporting aquatic life and downstream ecosystems.

The plant discharges into the Oder River basin, which flows through western Poland and empties into the Baltic Sea. This watershed supports diverse aquatic habitats and is important for migratory fish species. The Baltic Sea is sensitive to eutrophication from nutrient inputs, making effective wastewater treatment critical for reducing nitrogen and phosphorus loads.
