Dluga Wies Druga Wastewater Treatment Plant - Długa Wieś Druga, Poland

The Dluga Wies Druga wastewater treatment plant is located in the village of Długa Wieś Druga, within the gmina of Stawiszyn, powiat kaliski, in the Wielkopolskie Voivodeship of Poland. This facility serves a population of 833 residents, providing essential wastewater management for this small agglomeration. The plant employs advanced treatment processes, ensuring a high level of pollutant removal before discharge. With a designed capacity of 7200 m³/day and an actual discharge volume of 118.77 m³/day, the plant operates well below its capacity, indicating potential for future growth. As a Polish facility, it operates under national regulations that transpose the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates appropriate treatment levels based on population equivalents and receiving water sensitivity. The treated effluent is discharged into local watercourses that ultimately drain into the Warta River basin, part of the Oder River system flowing into the Baltic Sea. The plant's advanced treatment helps protect downstream aquatic ecosystems and supports the ecological health of the region's surface waters.

The plant discharges into local streams that feed into the Warta River, a major tributary of the Oder River, which flows into the Baltic Sea. The region's watershed supports diverse aquatic life and is important for maintaining water quality in the Oder basin. Advanced treatment at this plant reduces nutrient loading, helping to prevent eutrophication in downstream water bodies.
