Overview
Olesno wastewater treatment plant serves Szymiszów, Poland, treating wastewater for approximately 9,031 people. The plant operates under Polish regulations aligned with the EU Urban Waste Water Treatment Directive.
The Olesno wastewater treatment plant is located in Szymiszów, within the Opole Voivodeship of Poland. It serves a population of approximately 9,031, classifying it as a medium-sized agglomeration under EU standards. The facility is situated inland, away from coastal areas, and its operations are part of the regional wastewater management infrastructure. As a Polish treatment plant, Olesno is subject to 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 sensitive. The plant is expected to meet these regulatory standards to protect local water quality. The treated effluent from the plant is discharged into local water bodies that ultimately drain into the Oder River basin, which flows into the Baltic Sea. The plant plays a key role in safeguarding the ecological health of the region's rivers and downstream environments, supporting aquatic life and preventing eutrophication in the Baltic Sea.
Environmental context
The Olesno plant discharges into local streams that feed into the Oder River basin, which flows northward to the Baltic Sea. The region's watershed supports diverse aquatic ecosystems, including fish and macroinvertebrate communities. Proper treatment is essential to prevent nutrient loading and protect the ecological balance of the Oder and the Baltic Sea, which is sensitive to eutrophication.
