ETE Santa Quitéria - Advanced Wastewater Treatment Plant in Curitiba, Paraná

ETE Santa Quitéria is an advanced wastewater treatment plant located in the Santa Quitéria neighborhood of Curitiba, the capital city of Paraná state in southern Brazil. The plant serves a population of around 6,627 residents, reflecting its role in the municipal wastewater infrastructure of this major urban center. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants, ensuring high-quality effluent. With a discharge volume of 399.02 units, the facility operates under Brazil's national environmental regulations, which set stringent standards for wastewater treatment to protect water resources and public health. The treated effluent is discharged into local water bodies that ultimately drain into the Iguaçu River basin, a major watershed in southern Brazil. The Iguaçu River flows westward to join the Paraná River, forming part of the larger Río de la Plata Basin. This downstream connection highlights the plant's role in safeguarding water quality for aquatic ecosystems and downstream communities.

The plant discharges into the Iguaçu River basin, which flows into the Paraná River and eventually reaches the Río de la Plata estuary. This watershed supports diverse aquatic life and provides water for agriculture and urban use. The advanced treatment helps protect sensitive downstream habitats from nutrient pollution and organic loading.
