Parczew Wastewater Treatment Plant: Serving Parczew, Lublin Voivodeship, Poland

The Parczew wastewater treatment plant is located in the town of Parczew, in the Lublin Voivodeship of eastern Poland. The facility serves a population of around 11,165 residents, classifying it as a medium-sized agglomeration under Polish and EU regulations. As a municipal plant, it plays a key role in managing domestic wastewater from the local community. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations of this size are required to provide secondary treatment (biological treatment) as a minimum standard. The plant operates within Poland's national regulatory framework, which implements the directive through the Water Law Act and relevant environmental permits. The facility is expected to meet the effluent quality standards set for its population equivalent. The treated effluent is discharged into a local watercourse that ultimately drains into the Wieprz River, a tributary of the Vistula River, which flows into the Baltic Sea. The plant's operation helps protect the local aquatic environment and downstream water quality, supporting the ecological health of the Wieprz and Vistula river basins.

The Parczew plant discharges into a local stream that flows into the Wieprz River, a major tributary of the Vistula River. The Vistula drains into the Baltic Sea, making the plant part of a large transboundary watershed. The Wieprz River supports diverse aquatic life and is an important ecological corridor in the Lublin region. Proper wastewater treatment is essential to prevent nutrient pollution and maintain water quality in this sensitive river system.
