Overview
The Zambrów wastewater treatment plant serves Nagórki-Jabłoń and the Zambrów area in Podlaskie Voivodeship, Poland. It treats wastewater from a population of approximately 37,397 under EU regulatory standards.
The Zambrów wastewater treatment plant is located in Nagórki-Jabłoń, within the Zambrów municipality in Podlaskie Voivodeship, Poland. It serves a population of around 37,397 people, classifying it as a medium-sized agglomeration under EU classification. The plant is situated inland, away from coastal areas, and discharges into local water bodies. 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. For populations between 10,000 and 100,000, the directive mandates secondary treatment as a minimum, with more stringent requirements if the receiving waters are sensitive. It is expected to comply with national regulations aligned with EU standards. The plant's treated effluent is discharged into local rivers that eventually drain into the Baltic Sea via the Vistula or Narew river basins. This discharge contributes to the overall water quality in the region, supporting aquatic life and downstream ecosystems. The plant plays a key role in protecting the local watershed from untreated wastewater pollution.
Environmental context
The Zambrów plant discharges into the local river network, which is part of the Narew River basin, a tributary of the Vistula River. The Vistula flows northward into the Baltic Sea. The region's watershed supports diverse aquatic habitats and is important for migratory fish species. The plant's operations help maintain water quality in this sensitive inland ecosystem.
