Proszowki Wastewater Treatment Plant, Proszówki | Poland

Proszowki wastewater treatment plant is located in Proszówki, a village in the gmina Bochnia, powiat bocheński, województwo małopolskie, Poland. The plant serves a population of 914, classifying it as a small agglomeration under Polish and EU regulations. It is situated inland, away from coastal areas, and treats municipal wastewater from the local community. 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 in normal areas. The designed capacity is 2000 cubic meters per day, with a current discharge volume of 130.32 cubic meters per day, indicating operational capacity well below design. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into local water bodies, likely tributaries of the Vistula River basin, which ultimately flows into 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 aquatic ecosystems.

The plant discharges into the Vistula River basin, which drains into the Baltic Sea. The local watershed includes small streams and agricultural areas, where nutrient pollution from wastewater can impact water quality. Secondary treatment reduces organic load and suspended solids, helping to prevent eutrophication in downstream waters. The region's aquatic life, including fish and macroinvertebrates, benefits from controlled effluent discharge.
