Korsze Wastewater Treatment Plant, Glitajny, Poland - Secondary Treatment Facility

The Korsze wastewater treatment plant is located in Glitajny, within the gmina Korsze in the warmińsko-mazurskie voivodeship of Poland. It serves a population of approximately 3,008, classifying it as a small agglomeration under Polish and EU regulations. The plant is situated inland, away from coastal areas, and its operations are part of the regional wastewater infrastructure in northeastern Poland. The plant provides secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size discharging into freshwater. The plant has a designed capacity of 7,427 cubic meters per day, with an actual discharge volume of 428.89 cubic meters per day, indicating significant spare capacity. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into local water bodies within the Pregolya River basin, which flows into the Baltic Sea. The plant plays a crucial role in protecting the region's water quality, supporting aquatic life, and preventing eutrophication in downstream environments. Its operation aligns with Poland's commitments under the EU Water Framework Directive to achieve good ecological status for all water bodies.

The Korsze plant discharges into the Pregolya River basin, which ultimately drains into the Baltic Sea via the Vistula Lagoon. This region supports diverse aquatic ecosystems and is important for migratory fish species. The secondary treatment provided helps reduce nutrient loads, mitigating eutrophication risks in the sensitive Baltic Sea environment.
