ETE Cabrália Paulista: Secondary Wastewater Treatment in Cabrália Paulista, São Paulo

ETE Cabrália Paulista is a municipal wastewater treatment facility located in Cabrália Paulista, a small town in the state of São Paulo, Brazil. The plant serves a population of 3,840 residents, reflecting its role in managing domestic wastewater for this inland community. The plant provides secondary treatment, which is the standard biological process for removing organic matter and suspended solids. Under Brazil's national environmental regulations, including CONAMA resolutions, secondary treatment is appropriate for communities of this size to protect water quality in receiving water bodies. The treated effluent is discharged into local watercourses that ultimately drain into the Paraná River basin, one of South America's major river systems. The plant's operation helps safeguard downstream aquatic ecosystems and supports the region's water resources.

The plant discharges into local streams that flow into the Tietê River, a major tributary of the Paraná River basin. This watershed supports diverse aquatic life and provides water for agriculture and urban use downstream. The region's subtropical climate with seasonal rainfall influences the dilution capacity of receiving waters, making consistent treatment important for ecological balance.
