BIOK250 Wastewater Treatment Plant, Tymbark, Poland

BIOK250 is a secondary wastewater treatment plant located in Tymbark, within the małopolskie province of Poland. The facility serves a small population of 57 residents and reports a daily discharge volume of 8.13 cubic meters. Its designed capacity is 2000 cubic meters, indicating ample headroom for future growth. As a secondary treatment plant, BIOK250 provides biological treatment to reduce organic matter and suspended solids. The plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations of this scale. Polish regulations transpose this directive, ensuring compliance with national standards. The treated effluent is discharged into the local watershed, which ultimately drains into the Vistula River basin and then to the Baltic Sea. The plant plays a key role in protecting the region's water quality, particularly the downstream ecosystems that depend on clean water.

BIOK250 discharges into the local catchment that feeds the Dunajec River, a tributary of the Vistula River, which flows into the Baltic Sea. The area is part of the Carpathian foothills, supporting diverse aquatic life and serving as an important corridor for migratory fish. The plant's secondary treatment helps reduce nutrient loading, protecting downstream habitats from eutrophication.
