Pisarzowice Wastewater Treatment Plant: Advanced Treatment in Województwo Śląskie, Poland

Pisarzowice wastewater treatment plant is located in the village of Pisarzowice, within gmina Wilamowice, powiat bielski, województwo śląskie, Poland. The plant serves a population of 6,728 and operates with advanced treatment, ensuring high-quality effluent. Its designed capacity is 19,000 m³/day, with a current discharge volume of 959.31 m³/day. As a Polish facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment levels based on population equivalents and receiving water sensitivity. For a plant serving over 2,000 people, secondary treatment is mandatory, and advanced treatment is required in sensitive areas. Pisarzowice's advanced treatment exceeds these minimum standards, reflecting a commitment to environmental protection. The treated effluent is discharged into local watercourses that eventually drain into the Vistula River basin, which flows into the Baltic Sea. The plant plays a key role in protecting the local watershed from nutrient pollution and organic load, supporting aquatic life and downstream ecosystems.

The plant discharges into the local catchment of the Vistula River basin, which ultimately drains into the Baltic Sea. This region is part of a sensitive area where nutrient reduction is critical to prevent eutrophication. The advanced treatment at Pisarzowice helps reduce nitrogen and phosphorus loads, protecting downstream rivers and the Baltic marine environment from algal blooms and oxygen depletion.
