Dabrowno Wastewater Treatment Plant, Dąbrówno | Secondary Treatment, Small Population

The Dabrowno wastewater treatment plant is located in Dąbrówno, a town in the Warmian-Masurian Voivodeship of Poland. It serves a small population of 222 residents, reflecting its role in a rural community. The plant is situated near the address Przemysłowa, Zamkowy Młyn, within the administrative district of gmina Dąbrówno. The plant provides secondary treatment, which is the standard level required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations with a population equivalent below 2,000. Although the designed capacity is 13,900 m³/day, the actual discharge volume is 31.65 m³/day, indicating significant underutilization. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into a local water body, likely a small stream or river within the Vistula basin, as the region drains toward the Baltic Sea. The plant's operations help protect the local aquatic environment and downstream ecosystems from untreated wastewater pollution. Its inland location, over 50 km from the coast, reduces direct marine impact.

The plant discharges into a local watercourse that is part of the Vistula River basin, which ultimately flows into the Baltic Sea. The surrounding Warmian-Masurian region features numerous lakes and wetlands, making water quality protection crucial for maintaining biodiversity and supporting recreational activities. The secondary treatment ensures that effluent meets EU standards for organic matter and suspended solids, reducing nutrient loading that could cause eutrophication in downstream water bodies.
