Goscieradow Wastewater Treatment Plant, Długołęka, Poland

The Goscieradow wastewater treatment plant is located in Długołęka, within the świętokrzyskie province of Poland. It serves a population of approximately 3,009 people, classifying it as a small agglomeration under Polish and EU regulations. The plant is situated inland, away from coastal areas, and its operations are part of the local municipal wastewater infrastructure. The plant provides secondary treatment, which is the minimum standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. It has a designed capacity of 2,400 m³/day and currently discharges 429.04 m³/day of treated wastewater. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into a local water body, which eventually drains into the Vistula River basin, the largest river in Poland. The Vistula flows northward into the Baltic Sea, making the plant's operations relevant to the ecological health of the Baltic Sea catchment. Proper treatment helps protect downstream aquatic ecosystems and supports water quality standards in the region.

The plant discharges into a local watercourse that is part of the Vistula River basin. The Vistula flows through central Poland and empties into the Baltic Sea via the Gdańsk Bay. This watershed supports diverse aquatic life and is an important ecological corridor. The Baltic Sea is a sensitive brackish environment with limited water exchange, making nutrient and pollutant control critical to prevent eutrophication and maintain biodiversity.
