Jedlinsk Wastewater Treatment Plant, Jedlińsk | Secondary Treatment in Mazowieckie

The Jedlinsk wastewater treatment plant is located in the town of Jedlińsk, within the Radom County of Mazowieckie Voivodeship, Poland. This facility provides secondary treatment for a population of approximately 2,937 residents, classifying it as a small agglomeration under Polish and EU regulations. As a secondary treatment plant, Jedlinsk meets the minimum standards required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The plant has a designed capacity of 5,499 m³/day, with an actual discharge volume of 418.77 thousand m³ per year, indicating operational capacity well within its design limits. The treated effluent from the plant is discharged into local watercourses that ultimately drain into the Vistula River basin, which flows northward to the Baltic Sea. The plant plays a key role in protecting the local watershed from untreated sewage, supporting water quality in the region's rivers and downstream ecosystems.

The plant discharges into the Radomka River catchment, a tributary of the Vistula River, which flows into the Baltic Sea. The Vistula basin supports diverse aquatic life and is an important ecological corridor in Central Europe. Secondary treatment reduces organic pollutants and suspended solids, helping to maintain water quality in the downstream river system and the sensitive coastal environment of the Baltic Sea.
