Overview
ETE Italia is a wastewater treatment plant serving Várzea Paulista, São Paulo, Brazil. It treats wastewater for approximately 90,580 people under Brazil's national regulatory framework.
ETE Italia is a wastewater treatment plant located in Várzea Paulista, São Paulo, Brazil. Situated along Avenida Marginal do Rio Jundiaí, the plant serves a population of approximately 90,580 residents in the Jundiaí immediate region. As a municipal facility, it plays a key role in managing wastewater from this urban area within the São Paulo state. The plant operates under Brazil's national environmental regulations, which require adequate treatment for agglomerations of this scale. Brazilian standards, such as CONAMA resolutions, mandate treatment levels appropriate for protecting water quality. For a population of this size, secondary treatment is typically expected to reduce organic load and pathogens before discharge. Treated effluent from ETE Italia is discharged into the Rio Jundiaí, which flows into the Tietê River basin. The Tietê River is a major watercourse in São Paulo state, ultimately draining into the Paraná River system. This watershed supports diverse aquatic life and provides water for downstream communities, making effective treatment essential for ecological and public health.
Environmental context
The plant discharges into the Rio Jundiaí, a tributary of the Tietê River, which flows through the São Paulo metropolitan region and eventually joins the Paraná River basin. The Tietê River is ecologically significant, supporting fish populations and riparian habitats. Downstream waters are used for drinking water supply and agriculture, so nutrient and pathogen removal is critical to prevent eutrophication and protect human health in the densely populated region.
