Polnoc is a wastewater treatment plant located in Siewierz, within the Silesian Voivodeship of Poland. It serves a population of approximately 1,858 people, classifying it as a small agglomeration under Polish and EU regulations. The plant is operated by the local water and sewage utility, Zakład Usług Wodnych i Kanalizacyjnych w Siewierzu. The plant provides secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 7,150 m³/day and an average discharge volume of 264.92 m³/day, the facility operates well below its capacity, indicating room for future growth or seasonal variations. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into local water bodies, contributing to the protection of the region's aquatic ecosystems. The plant is located inland, away from coastal areas, and its operations are subject to Polish environmental regulations aligned with EU directives. Proper wastewater treatment in this region helps safeguard the quality of rivers and groundwater in the Upper Silesian industrial area.
Environmental context
The plant discharges into local watercourses that are part of the Vistula River basin, which ultimately drains into the Baltic Sea. The region is characterized by a mix of urban and industrial areas, making effective wastewater treatment crucial for preventing nutrient pollution and protecting downstream aquatic life. The plant's secondary treatment reduces organic load and helps maintain the ecological balance of the receiving waters.
