ETE Goianira Wastewater Treatment Plant - Goianira, Goiás, Brazil

ETE Goianira is a wastewater treatment facility located in Goianira, a city in the state of Goiás, Brazil, within the Goiânia metropolitan area. The plant serves a population of about 13,334 residents, classifying it as a medium-sized agglomeration under Brazilian wastewater management standards. As a plant in Brazil, ETE Goianira operates under the national regulatory framework established by the National Environment Council (CONAMA) and the Ministry of Cities. For agglomerations of this scale, secondary treatment is typically required to meet effluent quality standards before discharge. It is expected to comply with CONAMA Resolution 430/2011, which sets discharge limits for pollutants. The treated effluent from ETE Goianira is discharged into local water bodies that are part of the Paraná River basin, ultimately draining into the Paraná River and then the Río de la Plata estuary. The plant plays a crucial role in protecting the water quality of the region's rivers and streams, supporting both aquatic ecosystems and downstream water users.

ETE Goianira discharges into the Paraná River basin, which flows through central Brazil and eventually reaches the Río de la Plata estuary. The region's watershed supports diverse aquatic life and is important for agriculture and water supply. The plant's operation helps reduce nutrient and pathogen loads, protecting downstream ecosystems from eutrophication and contamination.
