Nozdrzec Wastewater Treatment Plant, Nozdrzec | Poland

The Nozdrzec wastewater treatment plant is located in the village of Nozdrzec, within the powiat brzozowski of województwo podkarpackie, Poland. The facility is currently closed, but its design capacity of 11,360 m³/day indicates it was intended to serve a medium-sized agglomeration in this rural region of southeastern Poland. Although the plant is not operational, its advanced treatment level aligns with the requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of this scale in sensitive areas, the directive mandates tertiary treatment to reduce nutrients and protect receiving waters. The plant's design suggests it was built to meet these standards. The plant's discharge would have entered local streams that drain into the San River, a major tributary of the Vistula River, which ultimately flows into the Baltic Sea. The San River supports diverse aquatic life and is an important ecological corridor in the Carpathian region.

The Nozdrzec plant, when operational, would have discharged into local watercourses that flow into the San River, a key tributary of the Vistula River. The Vistula drains into the Baltic Sea, making the plant part of a large transboundary basin. The San River valley supports diverse aquatic habitats and is an important migratory route for fish species. The advanced treatment level would have helped protect these downstream ecosystems from nutrient pollution.
