GOS w Kolbieli is a wastewater treatment plant located in Kołbiel, within the Mazowieckie Voivodeship of Poland. It serves a small population of 380 residents, reflecting its role in a rural or peri-urban setting. The plant is situated at Przemysłowa Street in the Piaski district of the gmina Kołbiel. The facility provides secondary treatment, which is the standard biological treatment stage required under Polish regulations aligned with the EU Urban Waste Water Treatment Directive (91/271/EEC). Although the designed capacity is 6000 m³/day, the actual discharge volume is 54.18 m³/day, indicating significant underutilization relative to its design. The treated effluent is discharged into local surface waters, likely tributaries of the Świder River, which flows into the Vistula River and ultimately reaches the Baltic Sea. This small plant plays a key role in protecting local water quality and the downstream aquatic ecosystem, particularly in the context of the Vistula basin's ecological significance.
Environmental context
The plant discharges into local watercourses that drain into the Świder River, a tributary of the Vistula River. The Vistula flows northward through Poland into the Baltic Sea via the Gdańsk Bay. This watershed supports diverse aquatic life and is an important ecological corridor in the region. The plant's secondary treatment helps reduce nutrient and organic loads, mitigating eutrophication risks in downstream waters.
