ETE Quirinópolis Wastewater Treatment Plant, Quirinópolis, Goiás, Brazil

ETE Quirinópolis is a wastewater treatment plant located in Quirinópolis, a city in the state of Goiás, Brazil. The plant serves an estimated population of 39,519 residents, placing it in the medium-agglomeration category. It is situated in the Central-West region of Brazil, an area characterized by tropical savanna climate and agricultural activity. As a Brazilian wastewater facility, ETE Quirinópolis operates under the national regulatory framework established by the National Environmental Council (CONAMA) and the National Water Agency (ANA). For agglomerations of this scale, Brazilian regulations typically require secondary treatment to meet effluent quality standards. The plant's designed capacity is reported as 1.00, though the unit is unspecified, indicating it is sized to handle the local wastewater load. The plant's treated effluent is discharged into a local water body, which ultimately drains into the Paraná River basin, one of South America's major river systems. This basin supports diverse aquatic ecosystems and is important for regional water supply and agriculture. Proper treatment at ETE Quirinópolis helps protect downstream water quality and ecological health.

The plant discharges into a tributary of the Paraná River basin, which flows through central Brazil and eventually reaches the Río de la Plata estuary. The local watershed supports agricultural irrigation and sustains aquatic biodiversity, including fish species important for regional fisheries. Effective wastewater treatment is critical to prevent nutrient loading and maintain water quality in this ecologically sensitive basin.
