ETE TANABI is a wastewater treatment plant located in Tanabi, within the state of São Paulo, Brazil. It serves a population of around 21,631 people, placing it in the medium-sized agglomeration category for Brazilian sanitation infrastructure. The facility is situated inland, far from the coast, and its operations are governed by Brazilian federal and state environmental standards. Brazil's wastewater treatment framework is primarily regulated by CONAMA resolutions and state-level environmental agencies such as CETESB in São Paulo. For a plant of this scale, secondary treatment is typically required to meet discharge standards that protect receiving water bodies. It is expected to comply with the applicable regulatory limits for organic matter and nutrient removal. The treated effluent from ETE TANABI is discharged into a local watercourse within the Paraná River basin, which ultimately flows into the Río de la Plata estuary. This basin supports diverse aquatic ecosystems and is important for regional water supply and agriculture. The plant plays a key role in preventing untreated sewage from entering local rivers, thereby protecting downstream water quality and public health.
Environmental context
ETE TANABI discharges into a tributary of the Paraná River basin, which drains into the Río de la Plata estuary. This watershed supports a variety of freshwater species and is used for irrigation and drinking water supply. The plant's treatment helps reduce nutrient and pathogen loads, mitigating eutrophication risks in downstream water bodies and safeguarding aquatic biodiversity.
