ETE SAO PEDRO I is a municipal wastewater treatment facility located in Andradina, within the state of São Paulo, Brazil. The plant serves a population of about 2,848 residents, classifying it as a small-scale treatment facility under Brazilian sanitation standards. It operates as part of the broader water infrastructure in the Araçatuba region. The plant provides secondary treatment, which is the standard biological treatment process required for most municipal wastewater in Brazil. Under the National Environmental Council (CONAMA) regulations, secondary treatment ensures significant reduction of organic matter and suspended solids. The plant's discharge volume is approximately 796 cubic meters per day, reflecting its service to a small community. The treated effluent is discharged into local waterways that ultimately drain into the Paraná River basin, one of the most important river systems in South America. The Paraná River flows through Brazil, Paraguay, and Argentina, eventually reaching the Río de la Plata estuary. The plant's operation helps protect downstream water quality and aquatic ecosystems in this extensive basin.
Environmental context
The plant discharges into tributaries of the Paraná River basin, which flows through the interior of São Paulo state. The Paraná River system supports diverse aquatic life and is a critical water resource for agriculture and urban areas. Downstream, the river feeds the La Plata Basin, one of the largest watersheds in South America, home to wetlands and floodplains that provide important ecological services. Protecting water quality in this basin is essential for maintaining regional biodiversity and water security.
