Komunalna Oczyszczalnia Sciekow w Wolbromiu - Municipal Wastewater Treatment Plant in Wolbrom, Poland

Komunalna Oczyszczalnia Sciekow w Wolbromiu is a municipal wastewater treatment plant located in Wolbrom, in the małopolskie province of southern Poland. The facility serves an estimated population of 25,997, classifying it as a medium-sized agglomeration under EU classification. As a Polish plant, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations between 10,000 and 150,000 population equivalent. The directive also mandates more stringent treatment if the receiving waters are designated as sensitive areas. The plant's treated effluent is discharged into local watercourses that ultimately drain into the Vistula River basin, which flows northward to the Baltic Sea. The region's aquatic ecosystems benefit from the plant's compliance with EU treatment standards, helping to protect downstream water quality and biodiversity.

The plant discharges into local streams that are part of the Vistula River basin, Poland's largest river system. The Vistula flows approximately 1,047 kilometers northward to the Baltic Sea, supporting diverse aquatic life and serving as an important ecological corridor. The region's water quality is influenced by agricultural and urban runoff, making effective wastewater treatment critical for maintaining the health of downstream ecosystems.
