CENTRUM Wastewater Treatment Plant, Mikołów, Silesian Voivodeship, Poland

CENTRUM is a wastewater treatment plant located in Mikołów, within the Silesian Voivodeship of southern Poland. The facility serves a population of about 26,027, placing it in the medium agglomeration category under EU classification. As a Polish plant, CENTRUM operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas. The plant is expected to meet these regulatory standards. The treated effluent from CENTRUM likely discharges into a local watercourse that ultimately drains into the Vistula River basin, which flows north to the Baltic Sea. The plant plays a key role in protecting local water quality and the downstream aquatic environment in the Silesian region.

The plant's discharge contributes to the local watershed, which is part of the Vistula River basin. The Vistula flows through central Poland and empties into the Baltic Sea, a semi-enclosed sea sensitive to nutrient pollution. The Silesian region is heavily industrialized, so effective wastewater treatment is critical to prevent eutrophication and protect aquatic life in downstream rivers and the Baltic.
