Straszecin Wastewater Treatment Plant, Straszęcin | Podkarpackie, Poland

The Straszecin wastewater treatment plant is located in Straszęcin, a village in the Podkarpackie Voivodeship of southeastern Poland. The facility serves a small population of approximately 1,013 people, reflecting its role in a rural community within the gmina of Żyraków. As a secondary treatment plant, it provides biological treatment to remove organic matter and suspended solids, meeting the standards required under Polish regulations that transpose the EU Urban Waste Water Treatment Directive (91/271/EEC). For small agglomerations under 2,000 population equivalent, the directive allows for appropriate treatment, and secondary treatment is typical for this scale. The plant discharges treated wastewater into the local watershed, which ultimately drains into the Wisłoka River, a tributary of the Vistula River. The Vistula flows northward into the Baltic Sea. The facility plays a key role in protecting local water quality and the downstream aquatic environment.

The treated effluent from Straszecin enters the local drainage network, which feeds into the Wisłoka River, a right-bank tributary of the Vistula. The Vistula River basin is the largest in Poland and supports diverse aquatic life, including migratory fish species. The plant's secondary treatment helps reduce nutrient and organic loads, contributing to the ecological health of the Wisłoka and the broader Vistula system before it reaches the Baltic Sea.
