Overview
Swieradow Zdroj wastewater treatment plant in Orłowice, Poland, serves 5,510 people with secondary treatment. It has a designed capacity of 9,900 m³/day and discharges 785.64 m³/day.
Swieradow Zdroj wastewater treatment plant is located in Orłowice, a village in the Lower Silesian Voivodeship of southwestern Poland. The facility serves a population of 5,510 and operates with secondary treatment, which is the standard for medium-sized agglomerations under Polish and EU regulations. The plant has a designed capacity of 9,900 m³/day and currently discharges 785.64 m³/day of treated wastewater. As a secondary treatment facility, it meets the requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations between 2,000 and 15,000 population equivalents, which mandate biological treatment to reduce organic matter and suspended solids. The treated effluent is discharged into local watercourses that flow into the Lusatian Neisse River, a tributary of the Oder River. The Oder ultimately drains into the Baltic Sea. The plant plays a key role in protecting the region's water quality, supporting aquatic ecosystems and downstream communities.
Environmental context
The plant discharges into small streams that feed the Lusatian Neisse River, which flows northward to join the Oder River near the German-Polish border. The Oder River basin supports diverse aquatic life, including fish species such as pike and perch, and is an important migratory corridor for birds. The Baltic Sea, the final receiving water body, is sensitive to nutrient pollution, making the plant's secondary treatment essential for reducing eutrophication risks.
