Nowa Wies Wastewater Treatment Plant, Nowa Wieś, Mazowieckie, Poland

Nowa Wies is a wastewater treatment plant located in the village of Nowa Wies, within the gmina Kozienice, powiat kozienicki, województwo mazowieckie, Poland. The plant provides secondary treatment and serves a population of 1,422, with a designed capacity of 4,067 thousand m³ per year and an actual discharge volume of 202.76 thousand m³ per year. As a secondary treatment facility in Poland, Nowa Wies operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The plant's capacity utilization is low relative to its design, indicating potential for future growth or seasonal variations in flow. The treated effluent is discharged into local surface waters, contributing to the Vistula River basin, which ultimately drains into the Baltic Sea. The plant plays a role in protecting the local aquatic environment and downstream ecosystems from untreated wastewater.

Nowa Wies discharges into the Vistula River basin, which flows northward through Poland and empties into the Baltic Sea via the Gulf of Gdansk. The local watershed supports diverse aquatic life and is an important ecological corridor. The plant's secondary treatment helps reduce nutrient loads and organic pollution, mitigating eutrophication risks in the Baltic Sea.
