Huta Stara B Wastewater Treatment Plant - Silesian Voivodeship, Poland

Huta Stara B is a wastewater treatment plant located in the village of Huta Stara B, within the gmina Poczesna, powiat częstochowski, in the Silesian Voivodeship of southern Poland. The plant serves a population of 1,654, placing it in the small agglomeration category under Polish and EU regulations. The facility provides secondary treatment, which is the minimum standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for discharges into freshwater from agglomerations of this size. The plant has a designed capacity of 3,200 m³/day and currently treats an average daily flow of 235.83 m³/day, indicating significant spare capacity. The treated effluent is discharged into a local watercourse that ultimately drains into the Warta River basin, part of the Oder River system flowing to the Baltic Sea. The plant plays a key role in protecting local streams and groundwater from untreated sewage, supporting the ecological health of the region's surface waters.

The plant discharges into a small tributary of the Warta River, which flows northward through central Poland and joins the Oder River near Kostrzyn nad Odrą. The Oder then empties into the Szczecin Lagoon and the Baltic Sea. The local watershed supports diverse aquatic life, including fish species such as pike and perch, and the area is part of a broader agricultural landscape where nutrient management is important to prevent eutrophication in downstream waters.
