Pruchnik Wastewater Treatment Plant: Secondary Treatment in podkarpackie, Poland

The Pruchnik wastewater treatment plant is located in the town of Pruchnik, in the podkarpackie province of southeastern Poland. The facility serves a population of approximately 1,706 residents, making it a small-scale municipal treatment plant. It is situated in a rural area within the powiat jarosławski district. The plant provides secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations with a population equivalent between 2,000 and 10,000. The plant has a designed capacity of 5,222 cubic meters per day, and the reported discharge volume is 243.25 cubic meters per day, indicating it operates well below its design capacity. The treated effluent is discharged into a local watercourse that ultimately drains into the San River, a tributary of the Vistula River, which flows into the Baltic Sea. The plant plays a key role in protecting local water quality and the downstream aquatic environment in the Vistula basin.

The plant discharges into a local stream that feeds into the San River, a major tributary of the Vistula River. The Vistula basin is the largest river basin in Poland and drains into the Baltic Sea. The downstream environment supports diverse aquatic life and is important for migratory fish species. The region's water quality is regulated under Polish law and the EU Water Framework Directive.
