ETE ITAPIRA Wastewater Treatment Plant, Itapira, São Paulo, Brazil

ETE ITAPIRA is a wastewater treatment plant located in Itapira, a city in the state of São Paulo, Brazil. The plant serves a population of around 72,048 residents, placing it in the medium-to-large agglomeration category for Brazilian sanitation infrastructure. It is situated inland, away from coastal areas, and its operations are part of the broader water management system in the Campinas region. Brazilian wastewater treatment plants are regulated by federal standards such as CONAMA Resolution 430/2011 and the National Water Resources Policy. For plants serving populations of this scale, secondary treatment is typically required to reduce organic load and suspended solids. The plant's treatment processes and capacity details are not publicly available, but the regulatory framework ensures compliance with discharge limits to protect water quality. The treated effluent from ETE ITAPIRA is discharged into local water bodies that eventually drain into the Rio Mogi Guaçu basin, a tributary of the Rio Pardo, which flows into the Rio Grande and ultimately the Paraná River system. This watershed supports diverse aquatic life and is important for regional water supply and agriculture. The plant plays a key role in preventing untreated sewage from entering these rivers, thereby safeguarding downstream ecosystems and public health.

ETE ITAPIRA discharges into the Rio Mogi Guaçu basin, part of the larger Rio Pardo watershed that flows into the Rio Grande and the Paraná River system. This inland basin supports diverse aquatic habitats and is critical for regional water supply and irrigation. The plant's operation helps reduce nutrient and organic pollution, protecting downstream water quality and ecological balance.
