Overview
Krotoszyn wastewater treatment plant serves Osusz and the surrounding area in województwo wielkopolskie, Poland. It treats wastewater from a population of approximately 60,251 under EU regulatory standards.
The Krotoszyn wastewater treatment plant is located in Osusz, within the gmina Krotoszyn in województwo wielkopolskie, Poland. It serves a population of around 60,251, classifying it as a medium-sized agglomeration under EU definitions. The plant is part of the municipal infrastructure managed by local authorities. As a Polish facility, the plant 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 EU standards to protect water quality. The treated effluent is discharged into local watercourses that ultimately drain into the Oder River basin, which flows into the Baltic Sea. The plant plays a key role in safeguarding the region's water resources and supporting downstream ecosystems, including the Baltic Sea's sensitive marine environment.
Environmental context
The Krotoszyn plant discharges into the Oder River basin, which flows northward through Poland and Germany before reaching the Baltic Sea. The Baltic Sea is a semi-enclosed, brackish sea with limited water exchange, making it vulnerable to nutrient pollution. The plant's treatment performance is critical for reducing nitrogen and phosphorus loads that can cause eutrophication in coastal waters.
Frequently asked questions
The Krotoszyn wastewater treatment plant is located in Osusz, a village in the gmina Krotoszyn, powiat krotoszyński, województwo wielkopolskie, Poland.
The plant serves a population of approximately 60,251 people, classifying it as a medium-sized agglomeration under EU standards.
The treated wastewater is discharged into local watercourses that are part of the Oder River basin, which ultimately flows into the Baltic Sea.
The plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size and may require advanced treatment if the receiving waters are sensitive.
For agglomerations of this scale in Poland, the EU directive mandates secondary treatment (biological treatment). In sensitive areas, additional nutrient removal (tertiary treatment) is required to reduce nitrogen and phosphorus.
