ETE CAMPOS DOURADOS - Secondary Wastewater Treatment in Goiânia, Goiás

ETE CAMPOS DOURADOS is a wastewater treatment plant located in Goiânia, the capital of Goiás state in Brazil's Centro-Oeste region. The plant serves a small population of 761 residents, reflecting its role in a localized catchment area within the urban fabric of Goiânia. The plant provides secondary treatment, which is the standard biological process for removing organic matter and suspended solids. Under Brazil's national environmental framework, CONAMA Resolution 430/2011 and the National Water Resources Policy (Law 9.433/1997) set effluent quality standards for discharges into water bodies. For a plant of this scale, secondary treatment meets typical regulatory requirements for inland freshwater systems. The treated effluent from ETE CAMPOS DOURADOS is discharged into a local water body that ultimately drains into the Paraná River basin, one of South America's major river systems. This basin supports extensive agriculture, hydroelectric power generation, and diverse aquatic ecosystems. The plant's operation helps protect downstream water quality in the region's streams and rivers.

The plant discharges into a tributary of the Paraná River basin, which flows through the Cerrado savanna biome and eventually reaches the Río de la Plata estuary. The Cerrado is a biodiversity hotspot, and maintaining water quality in its streams is critical for aquatic species and riparian habitats. The secondary treatment process reduces organic pollution, supporting the ecological health of downstream waters.
