Jazowsko Wastewater Treatment Plant - Secondary Treatment in Małopolskie, Poland

Jazowsko wastewater treatment plant is located in the village of Jazowsko, within gmina Łącko, powiat nowosądecki, województwo małopolskie, Poland. The plant serves a small population of 451 residents and operates under secondary treatment, meeting the standard requirements for small agglomerations under Polish and EU regulations. The plant has a design capacity of 4800 m³/day and currently discharges 64.31 m³/day of treated wastewater. As a secondary treatment facility, it provides biological treatment to reduce organic matter and suspended solids. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), secondary treatment is the minimum requirement for freshwater discharges from agglomerations of this size. The treated effluent is discharged into a local watercourse that ultimately drains into the Dunajec River, a tributary of the Vistula River, which flows into the Baltic Sea. The plant plays a key role in protecting the local watershed and downstream aquatic ecosystems from pollution.

The plant discharges into a small stream that flows into the Dunajec River, a major tributary of the Vistula River. The Vistula drains into the Baltic Sea, making the plant part of a large transboundary basin. The local watershed supports diverse aquatic life and is important for maintaining water quality in the Carpathian foothills region. Secondary treatment helps reduce nutrient loads that could otherwise contribute to eutrophication in downstream water bodies.
