ETE OSCAR BRESSANE Wastewater Treatment Plant, Oscar Bressane, São Paulo

ETE OSCAR BRESSANE is a municipal wastewater treatment plant located in Oscar Bressane, a small town in the state of São Paulo, Brazil. The plant serves a local population of approximately 1,984 residents, reflecting its role in managing domestic wastewater for this community. The plant provides secondary treatment, which is the standard level required for urban wastewater in Brazil under national regulations. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent from ETE OSCAR BRESSANE is discharged into a local watercourse that ultimately flows into the Paraná River basin, one of the largest river systems in South America. This basin supports diverse aquatic ecosystems and provides water for agriculture, industry, and drinking water downstream. Proper treatment at this plant helps protect water quality in the region.

The plant discharges into a tributary of the Paraná River basin, which drains into the Paraná River and eventually the Río de la Plata estuary. The basin supports a variety of aquatic life, including fish species important for local fisheries. Maintaining secondary treatment standards helps reduce nutrient and organic pollution, safeguarding downstream water quality and ecological health.
