Mycielin Wastewater Treatment Plant, Korzeniew, Poland

The Mycielin wastewater treatment plant is located in Korzeniew, within the gmina of Mycielin in powiat kaliski, województwo wielkopolskie, Poland. This facility serves a small population of 345 residents, reflecting its role in rural wastewater management. The plant is situated inland, away from coastal areas, and operates under Polish regulations that transpose the EU Urban Waste Water Treatment Directive. The plant provides secondary treatment, which is the standard biological treatment required for agglomerations under the EU Urban Waste Water Treatment Directive (91/271/EEC). For small communities like this, secondary treatment is appropriate to reduce organic matter and suspended solids before discharge. The designed capacity of 2200 cubic meters per day indicates the plant's potential to handle higher loads, though current discharge volume is 49.19 cubic meters per day. The treated effluent is discharged into local watercourses that eventually drain into the Warta River basin, part of the Oder River system flowing into the Baltic Sea. The plant's operation helps protect local streams and groundwater from untreated sewage, supporting aquatic life and water quality in the region's agricultural landscape.

The plant discharges into local water bodies that are part of the Warta River catchment, which flows into the Oder River and ultimately the Baltic Sea. The surrounding region is predominantly agricultural, so the plant's secondary treatment helps prevent nutrient pollution that could lead to eutrophication in downstream waters. The local watershed supports diverse aquatic habitats and is important for maintaining water quality in the broader Oder basin.
