Przedmiescie Czudeckie Wastewater Treatment Plant, Czudec, Poland

Przedmiescie Czudeckie is a wastewater treatment plant located in the village of Zawislocze, within the Czudec municipality in the Podkarpackie Voivodeship of southeastern Poland. The plant serves the local community of Czudec, with a population equivalent of approximately 2,419. It operates under the Polish regulatory framework, which implements the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this scale. The plant provides secondary treatment, which includes biological processes to reduce organic matter and suspended solids. With a designed capacity of 5,760 m³ per day and an average daily discharge volume of about 345 m³, the facility operates well below its maximum capacity, indicating adequate headroom for current demand. The treatment process meets the standards required for secondary treatment under EU regulations. The treated effluent is discharged into local watercourses that ultimately drain into the Wisłok River, a tributary of the San River, which flows into the Vistula River and then into the Baltic Sea. The plant plays a key role in protecting the local watershed from untreated sewage, supporting water quality in the region's rivers and downstream ecosystems.

The plant discharges into the Wisłok River basin, which flows into the San River, a major tributary of the Vistula River. The Vistula drains into the Baltic Sea, making the plant part of a large transboundary watershed. The local environment supports diverse aquatic life, including fish species such as barbel and chub, and the river corridor serves as an important ecological link in the Carpathian foothills region.
