Konarzyny Wastewater Treatment Plant, Zielona Huta, Poland

Konarzyny wastewater treatment plant is located in Zielona Huta, a village in the Konarzyny commune, Chojnice County, Pomeranian Voivodeship, Poland. This small-scale facility serves a population of 161, reflecting its role in a rural community. The plant is situated inland, away from coastal areas, and operates under Polish regulations that transpose the EU Urban Waste Water Treatment Directive. The plant provides secondary treatment, which is the standard biological treatment required for all agglomerations under the EU Urban Waste Water Treatment Directive (91/271/EEC). With a designed capacity of 2730 m³/day and an actual discharge volume of 22.96 m³/day, the plant operates well below its capacity, indicating it is sized for future growth or seasonal peaks. Secondary treatment typically involves biological oxidation and sedimentation. The treated effluent is discharged into a local water body, likely a small stream or river within the Brda or Vistula basin, ultimately draining into the Baltic Sea. The plant's operation helps protect local water quality and supports the ecological health of the region's surface waters, which are part of the broader Baltic Sea catchment area.

The plant discharges into a local watercourse that is part of the Vistula River basin, which flows into the Baltic Sea. The surrounding area is characterized by forests and agricultural land, with numerous small lakes and rivers. The treatment plant helps reduce nutrient loading to these sensitive waters, supporting aquatic biodiversity and preventing eutrophication in downstream ecosystems.
