Baldy Wastewater Treatment Plant, Bałdy | Advanced Treatment for Rural Community

The Baldy wastewater treatment plant is located in Bałdy, a village in the Warmian-Masurian Voivodeship of northeastern Poland. It serves a small population of 1,144 residents, reflecting its role in a rural community. The plant is part of Poland's municipal wastewater infrastructure, which operates under the EU Urban Waste Water Treatment Directive (91/271/EEC). The facility provides advanced treatment, which goes beyond the EU's minimum secondary treatment requirement for agglomerations of this size. With a designed capacity of 1,800 m³/day and an actual discharge volume of 163.12 m³/day, the plant operates well below its capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into local water bodies that eventually drain into the Baltic Sea via the Vistula Lagoon or directly through coastal rivers. The Warmian-Masurian region is known for its numerous lakes and rivers, making proper wastewater treatment essential for protecting aquatic ecosystems and recreational waters.

The plant's discharge enters local streams that flow into the Łyna River, a tributary of the Pregolya River, which ultimately reaches the Baltic Sea via the Vistula Lagoon. This watershed supports diverse aquatic life and is part of a region with many lakes and wetlands. Advanced treatment helps reduce nutrient loads, protecting downstream waters from eutrophication and preserving the ecological health of the Baltic Sea.
