Overview
Wlosan secondary treatment plant serves Lipnica Wielka, Poland, with a population equivalent of 1,477. Designed capacity is 7,000 m³/day, discharging 0.35 m³/day into the local watershed.
Wlosan is a wastewater treatment plant located in Lipnica Wielka, a village in the Lesser Poland Voivodeship of southern Poland. The plant serves a population of 1,477 and operates with secondary treatment, which is standard for small agglomerations under Polish and EU regulations. Its designed capacity of 7,000 m³/day indicates it can handle peak flows well above current discharge volumes. The plant's secondary treatment process removes organic matter and suspended solids, meeting the requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC) for settlements of this size. Polish regulations transpose this directive, and plants serving under 2,000 population equivalent are typically subject to less stringent requirements, though secondary treatment is common for environmental protection. The treated effluent is discharged into a local watercourse, part of the Vistula River basin, which ultimately drains into the Baltic Sea. The region is characterized by mountainous terrain and sensitive aquatic ecosystems, making proper wastewater treatment essential for protecting downstream water quality and biodiversity.
Environmental context
The plant discharges into the catchment of the Vistula River, Poland's longest river, which flows northward into the Baltic Sea. The local watershed includes the Orava River and its tributaries, supporting diverse aquatic life and serving as an important ecological corridor. The mountainous terrain of the Beskids region contributes to fast-flowing streams that require careful management to prevent nutrient pollution and sedimentation.
