Swiniary Nowe Wastewater Treatment Plant, Łoniów-Kolonia, Poland

Swiniary Nowe is a wastewater treatment plant located in Łoniów-Kolonia, within the świętokrzyskie province of Poland. It serves a small population of 36 people, reflecting its role in rural wastewater management. The plant operates under Polish regulations which transpose the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant provides secondary treatment, a standard level required for agglomerations of this size under EU directives. Its designed capacity is 2293 m³/day, with a current discharge volume of 5.13 m³/day, indicating significant spare capacity. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into the local watershed, which ultimately drains into the Vistula River basin. The Vistula flows northward through Poland into the Baltic Sea. The plant's operation helps protect local water quality and supports the ecological health of the downstream environment, including aquatic habitats in the Vistula catchment.

The plant discharges into the local watershed within the Vistula River basin, which drains into the Baltic Sea. The Vistula is Poland's longest river and supports diverse aquatic life, including migratory fish species. The plant's secondary treatment reduces nutrient loads, helping to mitigate eutrophication risks in the Baltic Sea, a sensitive marine environment.
