ETE Barueri Wastewater Treatment Plant - Barueri, São Paulo, Brazil

ETE Barueri is a municipal wastewater treatment plant located in Barueri, within the São Paulo metropolitan region of Brazil. The facility serves an estimated population of 92,345 residents, placing it in the medium-to-large agglomeration category for the region. As a plant in Brazil, ETE Barueri is subject to CONAMA Resolution 430/2011 and state-level environmental standards, which set effluent quality requirements for wastewater discharges. For agglomerations of this scale, secondary treatment is typically expected to reduce organic load and suspended solids before discharge. The plant's treated effluent is discharged into local water bodies that drain into the Tietê River basin, a major tributary of the Paraná River system. This river network ultimately flows to the Río de la Plata estuary, supporting diverse aquatic ecosystems and providing water resources for downstream communities.

The plant discharges into the Tietê River basin, which flows through the São Paulo metropolitan area and eventually joins the Paraná River. This watershed supports a range of aquatic life and is ecologically sensitive due to urban runoff and industrial inputs. The downstream environment includes the Paraná River floodplain and the Río de la Plata estuary, which are important for biodiversity and fisheries.
