Styków Wastewater Treatment Plant | Secondary Treatment in świętokrzyskie, Poland

The Styków wastewater treatment plant is located in the village of Styków, within gmina Brody, powiat starachowicki, in the świętokrzyskie voivodeship of Poland. The facility serves a population of approximately 2,019 people, making it a small-scale municipal treatment plant typical of rural communities in the region. As a secondary treatment plant, Styków employs biological processes to reduce organic matter and suspended solids. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations with a population equivalent (PE) between 2,000 and 10,000 are generally required to have secondary treatment, which this plant meets. The plant's designed capacity of 4,500 m³/day indicates it can handle peak flows beyond current discharge volumes. The treated effluent is discharged into local watercourses that eventually drain into the Vistula River basin, which flows northward to the Baltic Sea. The plant plays a key role in protecting downstream water quality in the region's rivers and groundwater, supporting both aquatic ecosystems and human water uses.

The plant's discharge enters small streams in the Kamienna River catchment, part of the larger Vistula River basin. The Vistula flows through central Poland to the Baltic Sea, supporting diverse aquatic life and providing water for agriculture and industry. The region's watershed is ecologically sensitive, with forested areas and wetlands that rely on clean water. Proper treatment at Styków helps prevent nutrient pollution and protects downstream habitats.
