Overview
ETE Italia is a municipal wastewater treatment plant in Várzea Paulista, São Paulo, Brazil, serving approximately 41,603 people. It operates under Brazil's national water quality regulations.
ETE Italia is a wastewater treatment plant located in Várzea Paulista, within the São Paulo state of Brazil. The facility serves a population of around 41,603 residents, classifying it as a medium-sized agglomeration under Brazilian sanitation standards. Its address along Avenida Marginal do Rio Jundiaí places it in the Jundiaí immediate region, part of the Campinas intermediate geographic region. Brazil's wastewater treatment sector is governed by the National Environmental Council (CONAMA) resolutions and the National Water Agency (ANA) guidelines. For plants of this scale, secondary treatment is typically required to meet effluent standards before discharge. It operates within the regulatory framework of São Paulo state's environmental agency (CETESB), which enforces discharge permits and water quality criteria. The plant's receiving water body is likely the Rio Jundiaí, which flows into the Atibaia River, then the Piracicaba River, and eventually the Tietê River, a major tributary of the Paraná River basin. This watershed supports diverse aquatic life and provides water for downstream communities, agriculture, and industry. Proper treatment at ETE Italia helps protect these water resources from nutrient pollution and pathogens.
Environmental context
The plant discharges into the Rio Jundiaí, part of the Tietê River basin, which drains into the Paraná River and ultimately the Río de la Plata estuary. This watershed is ecologically important, supporting fish populations and riparian habitats. Downstream water bodies are used for drinking water supply and irrigation, making nutrient and pathogen removal critical to prevent eutrophication and protect public health.
