ETE Santa Barbara Ponta Grossa - Secondary Wastewater Treatment in Ponta Grossa, Paraná

ETE Santa Barbara Ponta Grossa is a municipal wastewater treatment plant located in the Cará-Cará district of Ponta Grossa, Paraná, Brazil. The plant serves a population of approximately 3,479 residents, classifying it as a small-scale facility within the region's sanitation infrastructure. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. The plant's discharge volume of 460.51 m³/day indicates its operational scale. Brazilian wastewater treatment plants are regulated under CONAMA resolutions and state environmental agencies, which set effluent standards for BOD, COD, and other parameters. The treated effluent is discharged into local water bodies that drain into the Tibagi River basin, part of the Paraná River system. This watershed supports diverse aquatic life and provides water for downstream communities and agriculture. Proper treatment helps protect the ecological health of the region's streams and rivers.

The plant's discharge enters the local drainage network within the Tibagi River basin, which flows into the Paraná River and ultimately reaches the Río de la Plata estuary. This watershed supports diverse freshwater ecosystems, including fish species important for local fisheries. Effective secondary treatment reduces nutrient loads and organic pollution, helping maintain water quality in downstream habitats.
