Maciejowa Wastewater Treatment Plant, Maciejowa, Poland

Maciejowa wastewater treatment plant is located in the village of Maciejowa, within the gmina Łabowa, powiat nowosądecki, województwo małopolskie, Poland. The plant serves a population of 868, classifying it as a small agglomeration under Polish and EU regulations. The plant provides secondary treatment, which is the minimum required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The designed capacity is 1375 m³/day, and the current discharge volume is 123.76 m³/day, indicating significant spare capacity. 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 environment and downstream water quality.

The plant discharges into a small stream that feeds into the Dunajec River, part of the Vistula basin. The Vistula River flows northward through Poland and empties into the Baltic Sea via the Vistula Lagoon. The watershed supports diverse aquatic life and is important for regional biodiversity. The plant's secondary treatment helps reduce organic pollution and nutrient loads, protecting downstream ecosystems.
