Daleszyce Wastewater Treatment Plant - Secondary Treatment in Świętokrzyskie, Poland

The Daleszyce wastewater treatment plant is located in the town of Daleszyce, within województwo świętokrzyskie, Poland. It serves a population of 1,856 and operates as a secondary treatment facility, which is the standard level required by the EU Urban Waste Water Treatment Directive for agglomerations of this size. The plant has a designed capacity of 4,940 m³/day and currently discharges 264.64 m³/day of treated wastewater. As a Polish facility, it operates under national regulations that implement the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for inland plants serving between 2,000 and 10,000 population equivalent. The treated effluent is discharged into a local watercourse that eventually drains into the Vistula River basin, which flows northward into the Baltic Sea. The plant plays a key role in protecting local water quality and the downstream aquatic environment in the Świętokrzyskie region.

The Daleszyce plant discharges into a tributary of the Nida River, which flows into the Vistula River and ultimately reaches the Baltic Sea. The local watershed supports diverse aquatic life and is part of a region with sensitive karst geology, making groundwater protection important. The plant's secondary treatment helps reduce organic pollution and nutrient loads, safeguarding downstream ecosystems.
