Overview
Orzechowo wastewater treatment plant in Wielkopolskie, Poland, serves 3,066 people with secondary treatment. It discharges 437.16 m³/day and has a designed capacity of 7,021 m³/day.
The Orzechowo wastewater treatment plant is located in the village of Orzechowo, within the Miłosław commune in the Wielkopolskie Voivodeship of Poland. It serves a population of approximately 3,066 people, classifying it as a small agglomeration under Polish and EU regulations. The plant provides secondary treatment, which is the minimum standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The plant's designed capacity of 7,021 m³/day significantly exceeds the current discharge volume of 437.16 m³/day, indicating ample reserve capacity for future growth. The treated effluent is discharged into local watercourses that ultimately drain into the Warta River basin, a major tributary of the Oder River. The Oder flows into the Baltic Sea, making the plant part of a larger transboundary watershed. Proper treatment helps protect downstream aquatic ecosystems and the Baltic Sea from nutrient pollution.
Environmental context
The plant discharges into local streams that feed into the Warta River, which flows through western Poland before joining the Oder River near the German border. The Oder River empties into the Szczecin Lagoon and then the Baltic Sea. This watershed supports diverse aquatic life and is an important migratory corridor for fish. The Baltic Sea is sensitive to eutrophication from nutrient inputs, so effective secondary treatment at plants like Orzechowo helps reduce the regional nutrient load.
