ETE GOIAS Wastewater Treatment Plant, Goiás, Brazil

ETE GOIAS is a municipal wastewater treatment plant located in Goiás, a historic city in the state of Goiás, Brazil. The plant serves a population of approximately 8,746 people, placing it in the small-to-medium agglomeration category. As part of Brazil's national sanitation framework, the facility operates under regulations set by the National Environment Council (CONAMA) and state environmental agencies. Brazil's wastewater treatment standards require secondary treatment for urban areas, with more stringent requirements for sensitive water bodies. Plants of this scale typically employ biological treatment systems such as activated sludge or stabilization ponds. The plant's capacity and operational status are consistent with municipal infrastructure serving a small city in the interior of Brazil. The treated effluent from ETE GOIAS is discharged into local watercourses that drain into the Araguaia-Tocantins basin, one of Brazil's major river systems. This basin supports diverse aquatic ecosystems and is important for regional water supply and agriculture. The plant plays a key role in protecting downstream water quality and public health in the Cerrado biome.

ETE GOIAS discharges treated wastewater into local streams that flow into the Araguaia River, a major tributary of the Tocantins River basin. The receiving waters are part of the Cerrado savanna ecosystem, which is characterized by high biodiversity and seasonal rainfall patterns. The plant's operations help protect downstream aquatic habitats and water quality for communities relying on these rivers for drinking water and irrigation.
