Hyzne Wastewater Treatment Plant - Hyżne, podkarpackie, Poland

The Hyzne wastewater treatment plant is located in Hyżne, a town in the podkarpackie province of southeastern Poland. Serving a population of approximately 3,183, the plant is a key component of the local municipal infrastructure, ensuring that domestic wastewater is treated before being released into the environment. 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 of this size. With a designed capacity of 4,000 cubic meters per day and a current discharge volume of 453.85 cubic meters per day, the facility operates well within its capacity, indicating efficient management. The treated effluent is discharged into local watercourses that eventually drain into the Wisłok River, a tributary of the San River, which flows into the Vistula River and ultimately reaches the Baltic Sea. This connection underscores the plant's role in protecting downstream aquatic ecosystems and the broader Baltic Sea environment.

The plant's discharge enters the local drainage network, which flows into the Wisłok River, a tributary of the San River. The San River joins the Vistula River, which empties into the Baltic Sea. The region's watershed supports diverse aquatic life, and the plant's secondary treatment helps reduce nutrient loads that could otherwise contribute to eutrophication in downstream water bodies.
