ETE Goianésia Wastewater Treatment Plant, Goianésia, Goiás, Brazil

ETE Goianésia is a wastewater treatment plant located in Goianésia, a city in the state of Goiás, Brazil. The plant serves an estimated population of 46,495, placing it in the medium agglomeration category for Brazilian wastewater infrastructure. As part of the municipal sanitation system, it plays a key role in managing domestic wastewater for the urban area. Brazil's wastewater treatment standards are governed by federal regulations, including CONAMA resolutions and the National Sanitation Plan (PLANSAB). For plants of this scale, secondary treatment is typically required to reduce organic load and pathogens before discharge. It operates within the regulatory framework that mandates compliance with effluent quality standards. The treated effluent from ETE Goianésia is discharged into local water bodies that drain into the Tocantins River basin, ultimately reaching the Atlantic Ocean. The region's watershed supports diverse aquatic life and is important for local agriculture and water supply. Proper treatment helps protect downstream ecosystems and public health.

The plant's discharge flows into tributaries of the Tocantins River, a major Brazilian river system that drains into the Atlantic Ocean near the Amazon delta. The Tocantins basin supports diverse aquatic habitats, including floodplains and wetlands that are critical for fish spawning and migratory birds. Effective wastewater treatment is essential to prevent nutrient pollution and maintain water quality in this ecologically sensitive watershed.
