Blazowa Wastewater Treatment Plant: Advanced Treatment in Błażowa, Poland

The Blazowa wastewater treatment plant is located in Błażowa, a town in the Podkarpackie Voivodeship of southeastern Poland. This facility serves a population of 1,354, classifying it as a small agglomeration under Polish and EU regulations. As an advanced treatment plant, Blazowa goes beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The plant has a designed capacity of 3,000 m³/day and currently treats an average of 193.06 m³/day, indicating significant reserve capacity. The treated effluent is discharged into a local watercourse that eventually drains into the Wisłok River, a tributary of the San River, which flows into the Vistula River and ultimately reaches the Baltic Sea. The plant's advanced treatment helps protect the sensitive aquatic ecosystems of the Vistula basin.

The plant discharges into a local stream that flows into the Wisłok River, part of the Vistula River basin. The Vistula is Poland's largest river and drains into the Baltic Sea, a semi-enclosed sea with eutrophication concerns. Advanced treatment at Blazowa reduces nutrient loads, supporting the ecological health of downstream waters and the Baltic Sea.
