ETE BRAUNA Wastewater Treatment Plant, Braúna, São Paulo, Brazil

ETE BRAUNA is a municipal wastewater treatment plant located in Braúna, a city in the state of São Paulo, Brazil. The plant serves a population of about 4,593 people, classifying it as a small-scale facility within the region's sanitation infrastructure. The plant provides secondary treatment, which is the standard level required by Brazilian regulations for communities of this size. Secondary treatment typically involves biological processes to remove organic matter and suspended solids, ensuring the effluent meets basic environmental standards before discharge. The treated wastewater is discharged into local water bodies, likely tributaries of the Tietê River basin, which flows through São Paulo state and ultimately reaches the Paraná River system. This discharge supports downstream aquatic ecosystems and agricultural water use in the region.

The plant discharges into local streams that are part of the Tietê River basin, a major watershed in São Paulo state. The Tietê River flows through the state and eventually joins the Paraná River, which drains into the Río de la Plata estuary. The region's aquatic ecosystems support diverse fish species and are important for local biodiversity. Proper treatment helps protect water quality in this sensitive watershed.
