ETE Caiapônia Wastewater Treatment Plant, Caiapônia, Goiás, Brazil

ETE Caiapônia is a municipal wastewater treatment plant located in Caiapônia, Goiás, Brazil. The facility serves a population of approximately 12,180 residents, placing it in the small-to-medium agglomeration category. The plant is situated in the Central-West region, an area characterized by the Cerrado biome and seasonal rainfall patterns. Brazil's wastewater treatment sector is regulated by the National Environment Council (CONAMA) and state environmental agencies. For agglomerations of this scale, secondary treatment is typically required to meet discharge standards. The plant's operational details, including treatment process and capacity, are part of the municipal sanitation framework overseen by local authorities. The treated effluent from ETE Caiapônia 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. Proper treatment helps protect downstream water quality and biodiversity in the Cerrado region.

The plant discharges into streams that flow into the Paraná River basin, which ultimately reaches the Río de la Plata estuary. The Cerrado biome surrounding Caiapônia is a biodiversity hotspot, and maintaining water quality in local water bodies is critical for preserving aquatic habitats and supporting regional agriculture. The plant's treatment performance directly influences the ecological health of downstream ecosystems.
