Overview
Koronowo wastewater treatment plant serves approximately 12,400 residents in województwo kujawsko-pomorskie, Poland. It operates under the EU Urban Waste Water Treatment Directive, which mandates secondary treatment for agglomerations of this size.
The Koronowo wastewater treatment plant is located in the town of Koronowo, within the powiat bydgoski of województwo kujawsko-pomorskie, Poland. It serves a population of approximately 12,400, placing it in the medium agglomeration category under EU classification. The plant is situated near the Brda River, a tributary of the Vistula, which ultimately drains into the Baltic Sea. As a Polish facility serving a population between 10,000 and 15,000, the plant is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC). This directive requires secondary treatment for all discharges from agglomerations of this scale, with more stringent tertiary treatment if the receiving waters are designated as sensitive areas. Regulatory compliance ensures appropriate treatment standards. The plant discharges treated wastewater into the local watershed, which flows into the Brda River and then the Vistula River, the longest river in Poland. The Vistula empties into the Baltic Sea via the Gdańsk Bay. This water body supports diverse aquatic life and is an important ecological corridor in northern Poland. Proper treatment at Koronowo helps protect downstream water quality and the sensitive Baltic Sea ecosystem.
Environmental context
The Koronowo plant discharges into the Brda River, a tributary of the Vistula River, which flows northward to the Baltic Sea. The Vistula basin supports diverse aquatic habitats and is a critical migratory route for fish species. The Baltic Sea is a brackish, semi-enclosed sea with limited water exchange, making it sensitive to nutrient pollution. Effective wastewater treatment at Koronowo helps reduce nutrient loads that could contribute to eutrophication in the Baltic.
