ETE CANDOI Wastewater Treatment Plant, Candói, Paraná, Brazil

ETE CANDOI is a wastewater treatment plant located in Candói, within the Guarapuava Intermediate Geographic Region of Paraná, Brazil. The facility serves a small population of around 2,149 residents, providing secondary-level treatment for municipal wastewater. The plant operates under Brazil's national environmental regulations, which require secondary treatment for communities of this size. With a discharge volume of 352.51 cubic meters, the facility manages the wastewater generated by the local population, ensuring compliance with federal water quality standards. The treated effluent is discharged into the local watershed, which ultimately drains into the Iguaçu River basin. This river system supports diverse aquatic life and is an important water resource for the region. The plant's operation helps protect downstream water quality and contributes to the ecological health of the Paraná state waterways.

The plant discharges into the Iguaçu River basin, a major watershed in southern Brazil that flows into the Paraná River and eventually the Río de la Plata estuary. The region's aquatic ecosystems support diverse fish species and provide habitat for migratory birds. Proper wastewater treatment is essential to prevent nutrient loading and maintain water quality in this ecologically sensitive basin.
