Bielawa Wastewater Treatment Plant, Dzierżoniów, Poland

The Bielawa wastewater treatment plant is located in Dzierżoniów, in the Lower Silesian Voivodeship of Poland. It serves a population of approximately 37,243, classifying it as a medium agglomeration under EU regulations. The plant is part of the municipal infrastructure managing wastewater from the city and surrounding areas. As a Polish facility, the plant operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which mandates secondary treatment for agglomerations of this size. The directive also requires more advanced treatment if the receiving waters are sensitive areas. The regulatory framework ensures compliance with national and EU standards for effluent quality. The treated wastewater is discharged into local water bodies that ultimately drain into the Oder River basin, which flows northward to the Baltic Sea. The plant plays a key role in protecting the region's water resources, supporting aquatic life in downstream rivers and contributing to the ecological health of the Baltic Sea catchment area.

The Bielawa plant discharges into the local watershed, which is part of the Oder River basin. The Oder flows through Poland and Germany before reaching the Baltic Sea. This region supports diverse aquatic ecosystems, including fish spawning grounds and migratory bird habitats. Proper wastewater treatment is essential to prevent nutrient pollution and maintain water quality in the sensitive Baltic Sea environment.
