Miastków Kościelny Wastewater Treatment Plant - Secondary Treatment in Mazowieckie, Poland

The Miastków Kościelny wastewater treatment plant is located in the village of Miastków Kościelny, within the powiat garwoliński of województwo mazowieckie, Poland. This facility serves a small population of 114 residents, reflecting its role in a rural community. The plant is designed with a capacity of 240 m³/day and currently treats a daily flow of 16.26 m³. As a secondary treatment plant, it meets the standard requirements under Polish regulations, which transpose the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations with a population equivalent under 2,000, the directive requires appropriate treatment, which secondary treatment fulfills. The plant's operation is part of Poland's commitment to improving water quality across the Vistula basin. The treated effluent from the plant is discharged into local watercourses that ultimately drain into the Vistula River, Poland's longest river, which flows into the Baltic Sea. The plant helps protect the local watershed from nutrient pollution, supporting aquatic life in the region's rivers and contributing to the ecological health of the Baltic Sea.

The plant discharges into local streams that feed into the Vistula River basin, which drains into the Baltic Sea. The Vistula is a major European river supporting diverse fish species and migratory birds. The region's agricultural landscape means nutrient management is critical to prevent eutrophication in downstream waters, including the Baltic Sea, which is sensitive to nitrogen and phosphorus loads.
