Strawczyn Wastewater Treatment Plant | Secondary Treatment, Poland

The Strawczyn wastewater treatment plant is located in the village of Burdawa, within the gmina of Strawczyn in powiat kielecki, województwo świętokrzyskie, Poland. It serves a population of 5,695, classifying it as a small agglomeration under Polish and EU regulations. The plant is situated inland, away from coastal areas. 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. Its designed capacity is 6,770 m³/day, and it currently discharges an average of 812.02 m³/day of treated wastewater. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into local watercourses that ultimately drain into the Vistula River basin, which flows northward into the Baltic Sea. The plant plays a key role in protecting the region's water quality, supporting aquatic ecosystems and downstream communities that rely on the Vistula's waters.

The plant discharges into small streams in the Świętokrzyskie region, which are part of the larger Vistula River basin. The Vistula flows through central Poland and empties into the Baltic Sea via the Gdańsk Bay. The watershed supports diverse aquatic life, including fish species such as pike and bream, and provides important ecosystem services for agriculture and drinking water. The plant's secondary treatment helps reduce nutrient loads, mitigating eutrophication risks in downstream waters.
