Dankowice Wastewater Treatment Plant | Secondary Treatment in śląskie, Poland

Dankowice wastewater treatment plant is located in the village of Dankowice, within gmina Wilamowice, powiat bielski, in the śląskie province of southern Poland. The plant serves a population of 1,244 and operates as a secondary treatment facility, which is the standard for small agglomerations under Polish regulations implementing the EU Urban Waste Water Treatment Directive. With a designed capacity of 2,350 m³/day and an average discharge volume of 177.38 m³/day, the plant operates well below its capacity. As a secondary treatment plant, it removes organic matter and suspended solids, meeting the requirements for inland discharge under Polish law. The facility is part of the national wastewater infrastructure managed by local water utilities. The plant's treated effluent is discharged into local watercourses that eventually drain into the Vistula River basin, which flows north to the Baltic Sea. The surrounding region is characterized by agricultural and residential areas, and the plant plays a key role in protecting local streams from nutrient pollution and maintaining water quality in the broader catchment.

The plant discharges into small streams within the Vistula River basin, which ultimately flows into the Baltic Sea. The Baltic Sea is a semi-enclosed sea sensitive to eutrophication from nutrient inputs. The plant's secondary treatment helps reduce organic and nutrient loads, supporting the ecological health of local water bodies and contributing to regional efforts to mitigate Baltic Sea eutrophication.
