ETE Silvania Wastewater Treatment Plant, Silvânia, Goiás, Brazil

ETE Silvania is a wastewater treatment plant located in Silvânia, a municipality in the state of Goiás, Brazil. The plant serves an estimated population of 12,436 residents, placing it in the small-to-medium agglomeration category for Brazilian wastewater infrastructure. As a facility in Brazil, ETE Silvania operates under the national regulatory framework established by the National Environment Council (CONAMA) and the Ministry of Cities. Brazilian regulations require adequate wastewater treatment for urban areas, with standards varying by receiving water body classification. For a plant of this scale, secondary treatment is typically expected to meet effluent quality standards. The plant's treated effluent is discharged into local water bodies within the Paraná River basin, which ultimately drains into the Río de la Plata estuary. The surrounding region features Cerrado savanna ecosystems, and proper treatment helps protect downstream aquatic habitats and water quality for communities relying on these resources.

ETE Silvania discharges into local streams that are part of the Paraná River basin, one of South America's largest drainage systems. The Paraná River flows southward through Brazil, Paraguay, and Argentina before emptying into the Río de la Plata estuary. The Cerrado biome surrounding Silvânia is a biodiversity hotspot, and the plant's operations help maintain water quality in downstream rivers that support diverse aquatic life and provide water for agriculture and human consumption.
