Psary Stare Wastewater Treatment Plant, Psary Stare | Poland

Psary Stare wastewater treatment plant is located in the village of Psary Stare, within gmina Moszczenica, powiat piotrkowski, województwo łódzkie, Poland. The plant serves a small population of 227 residents, reflecting its role in a rural community. As a secondary treatment facility, it provides biological treatment to reduce organic pollutants before discharge. The plant has a designed capacity of 1200 m³/day and currently discharges 32.37 m³/day of treated wastewater. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), small agglomerations like this are required to provide appropriate treatment, and secondary treatment meets the standard for inland freshwater discharge. The plant's operation is subject to Polish environmental regulations aligned with EU directives. The treated effluent is discharged into local watercourses within the Vistula River basin, which ultimately drains into the Baltic Sea. The plant helps protect local streams and groundwater from untreated sewage, supporting aquatic life and water quality in the region's agricultural landscape.

The plant discharges into small streams within the Vistula River basin, which flows northward through Poland to the Baltic Sea. The surrounding area is predominantly agricultural, so the plant's secondary treatment helps prevent nutrient pollution that could lead to eutrophication in downstream waters. The Baltic Sea is sensitive to nutrient inputs, making effective wastewater treatment crucial for regional marine health.
