Lipa Wastewater Treatment Plant, Podkarpackie, Poland

Lipa wastewater treatment plant is located in the village of Lipa, within gmina Zaklików, powiat stalowowolski, in the podkarpackie province of southeastern Poland. The plant serves a population of 1,210 and operates with secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive for agglomerations of this size. The plant has a designed capacity of 1,875 m³/day and currently discharges 172.53 m³/day of treated wastewater. As a secondary treatment facility, it removes organic matter and suspended solids, meeting the effluent standards set by Polish regulations transposing the EU directive. The plant is part of the municipal wastewater infrastructure for the Lipa area. The treated effluent is discharged into local watercourses that eventually drain into the Vistula River basin, which flows northward to the Baltic Sea. The plant plays a key role in protecting local streams and groundwater from untreated sewage, supporting the ecological health of the region's aquatic ecosystems.

The plant discharges into small streams within the Vistula River basin, which ultimately drains into the Baltic Sea. The local watershed supports diverse aquatic life and is part of a region with agricultural and forested landscapes. The secondary treatment helps reduce nutrient loads that could otherwise contribute to eutrophication in downstream water bodies.
