ETE Regente Feijó Wastewater Treatment Plant, Regente Feijó, São Paulo

ETE Regente Feijó is a wastewater treatment plant located in the Vila Nova district of Regente Feijó, within the Presidente Prudente region of São Paulo state, Brazil. The plant serves a population of around 17,462 residents, placing it in the small-to-medium agglomeration category for Brazilian wastewater infrastructure. Brazil's wastewater treatment standards are governed by CONAMA Resolution 430/2011 and state-level regulations, which require appropriate treatment for municipal effluents. The plant's design capacity is not recorded, but the population served suggests a moderate-scale operation. The treated effluent from ETE Regente Feijó is discharged into local water bodies that drain into the Paraná River basin, one of South America's major river systems. This basin supports diverse aquatic ecosystems and provides water for agriculture and urban use downstream. Proper treatment at this plant helps protect water quality in the region's streams and rivers.

ETE Regente Feijó discharges into local streams that flow into the Paraná River basin, which ultimately reaches the Río de la Plata estuary. The Paraná basin supports extensive wetlands and floodplains that are ecologically sensitive, providing habitat for fish, birds, and other wildlife. Effective wastewater treatment is crucial to prevent nutrient loading and maintain water quality in this important hydrological system.
