ETE EDeIA Wastewater Treatment Plant, Edéia, Goiás, Brazil

ETE EDeIA is a wastewater treatment plant located in Edéia, a municipality in the state of Goiás, Brazil. The plant serves a population of around 10,036 residents, placing it in the small-to-medium agglomeration category for Brazilian wastewater infrastructure. It operates within the Central-West region, an area characterized by agricultural activity and seasonal rainfall patterns. As a Brazilian wastewater facility, ETE EDeIA is subject to national regulations under CONAMA Resolution 430/2011 and the National Water Resources Policy (Law 9.433/1997), which set discharge standards for treated effluent. For plants serving populations of this scale, secondary treatment is typically required to reduce organic load and suspended solids before discharge. It is expected to meet the regulatory standards for its size class. The treated effluent from ETE EDeIA is discharged into local water bodies that drain into the Paraná River basin, one of the most important hydrological systems in South America. The downstream environment supports diverse aquatic life and is used for agriculture, water supply, and recreation. Proper treatment at this plant helps protect water quality in the region's rivers and contributes to the overall health of the Paraná basin.

The plant discharges into local streams that flow into the Paraná River basin, which ultimately drains into the Río de la Plata estuary. The region's waterways support agricultural irrigation and provide habitat for fish species such as the dourado and pacu. Maintaining effluent quality is important to prevent nutrient enrichment and protect downstream aquatic ecosystems.
