Overview
Oborniki Sl ul Grunwaldzka is an advanced wastewater treatment plant serving Oborniki Śląskie, Poland. It treats municipal wastewater for approximately 5,067 people with a designed capacity of 8,423 m³/day.
Oborniki Sl ul Grunwaldzka is a wastewater treatment plant located in Oborniki Śląskie, a town in the Lower Silesian Voivodeship of Poland. The plant serves a population of around 5,067 people, classifying it as a small to medium agglomeration under Polish and EU regulations. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive receiving waters. The plant has a designed capacity of 8,423 m³/day and currently discharges a daily volume of 722.48 m³, indicating significant spare capacity. The treated effluent is discharged into a local watercourse, which ultimately drains into the Oder River basin. The Oder River flows northward through Poland and into the Baltic Sea, making the plant's advanced treatment important for reducing nutrient loads that could contribute to eutrophication in the Baltic Sea.
Environmental context
The plant discharges into a local tributary of the Oder River basin, which flows into the Baltic Sea. The Baltic Sea is a semi-enclosed sea highly sensitive to nutrient pollution, where advanced treatment helps mitigate algal blooms and oxygen depletion. The surrounding region is part of the Lower Silesian lowlands, with agriculture and small urban settlements influencing local water quality.
