Nowa Wies Wastewater Treatment Plant, Trzebownisko, Podkarpackie, Poland

Nowa Wies is a wastewater treatment plant located in Trzebownisko, a municipality in the Podkarpackie region of southeastern Poland. The facility serves a population of approximately 42,176, classifying it as a medium-sized agglomeration under EU classification standards. As a Polish plant, Nowa Wies operates under the national implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of this size, the directive requires at least secondary treatment, with more stringent requirements if the receiving waters are designated as sensitive areas. The plant's treatment processes and capacity are managed to meet these regulatory standards. The treated effluent from Nowa Wies is discharged into local watercourses that eventually drain into the Vistula River basin, which flows northward into the Baltic Sea. The facility plays a key role in protecting the region's water quality and supporting the ecological health of downstream aquatic environments.

The plant discharges into the Vistula River basin, which ultimately flows into the Baltic Sea via the Gulf of Gdansk. This watershed supports diverse aquatic life and is an important ecological corridor. The Baltic Sea is a semi-enclosed sea sensitive to nutrient pollution, making effective wastewater treatment critical for preventing eutrophication and maintaining marine ecosystem health.
