Overview
Ozarow wastewater treatment plant serves Zawichost, Poland, providing secondary treatment for a population of 5,607. It discharges 799.47 m³/day of treated wastewater, with a designed capacity of 7,510 m³/day.
The Ozarow wastewater treatment plant is located in Zawichost, within the świętokrzyskie province of Poland. It serves a population of approximately 5,607 people, classifying it as a small to medium agglomeration under Polish and EU regulations. The plant operates with secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size discharging into freshwater. The facility has a designed capacity of 7,510 m³/day and currently treats an average daily volume of 799.47 m³/day, indicating significant spare capacity. The treated effluent is discharged into the local watershed, which ultimately drains into the Vistula River basin. The Vistula flows northward through Poland into the Baltic Sea, making the plant's performance important for downstream water quality and the ecological health of the Baltic Sea ecosystem.
Environmental context
The plant discharges into the Vistula River basin, Poland's largest river system, which flows into the Baltic Sea. The Baltic Sea is a semi-enclosed, brackish sea sensitive to nutrient pollution, where wastewater discharges contribute to eutrophication. Secondary treatment helps reduce organic load and suspended solids, but nutrient removal may be needed for sensitive areas.
