Suszec Wastewater Treatment Plant | Secondary Treatment in śląskie, Poland

The Suszec wastewater treatment plant is located in the town of Suszec, in the śląskie province of southern Poland. The facility serves a population of approximately 4,093 residents, classifying it as a small agglomeration under Polish and EU regulations. The plant provides secondary treatment, which is the minimum standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for inland freshwater discharges from agglomerations of this size. The plant's designed capacity is 2,900 m³/day, and it currently discharges an average of 583.60 m³/day of treated effluent. The treated wastewater 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 region's surface waters from nutrient pollution and supporting the ecological health of the downstream aquatic environment.

The Suszec plant discharges into small streams that feed the Vistula River basin, one of Poland's major river systems. The Vistula flows through the country's central lowlands and empties into the Baltic Sea via the Gdańsk Bay. This watershed supports diverse aquatic life and is an important ecological corridor for migratory fish species. The plant's secondary treatment helps reduce organic load and nutrient inputs, mitigating eutrophication risks in the Baltic Sea.
