GOS w Ostrowach nad Oksza Wastewater Treatment Plant, Borowa, Poland

GOS w Ostrowach nad Oksza is a municipal wastewater treatment plant located in Borowa, within the Silesian Voivodeship of Poland. The facility serves a population of approximately 4,000, classifying it as a small agglomeration under Polish and EU regulations. The plant is situated in a rural area near the village of Młodzianowa, part of the gmina Miedźno. The plant provides secondary treatment, which is the minimum standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for discharges into freshwater bodies from agglomerations of this size. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant has a designed capacity of 3,753 cubic meters per day and reports a discharge volume of 573.76 cubic meters per day, indicating it operates well below capacity. The treated effluent is discharged into local watercourses that ultimately drain into the Oksza River, a tributary of the Warta River, which flows into the Oder River and then to the Baltic Sea. The plant plays a key role in protecting the local aquatic environment from nutrient pollution and organic loading, supporting water quality in the region's rivers and downstream ecosystems.

The plant discharges into the Oksza River, a tributary of the Warta River, which flows into the Oder River and eventually reaches the Baltic Sea. This watershed supports diverse aquatic life and is important for regional biodiversity. The secondary treatment provided helps reduce organic pollutants and nutrients, mitigating eutrophication risks in downstream waters.
