ETE JATAI Wastewater Treatment Plant, Jataí, Goiás, Brazil

ETE JATAI is a municipal wastewater treatment plant located in Jataí, Goiás, Brazil. The facility serves an estimated population of 59,551 people, placing it in the medium agglomeration category for Brazilian wastewater infrastructure. The plant is situated in the Central-West region, an area characterized by tropical savanna climate and agricultural activity. Brazil's wastewater treatment sector is regulated by the National Environmental Council (CONAMA) and the Ministry of Cities, with standards set by CONAMA Resolution 430/2011 for effluent quality. For agglomerations of this scale, secondary treatment is typically required to meet organic matter and solids removal standards. The plant's operational context reflects Brazil's ongoing efforts to expand sanitation coverage under the National Sanitation Plan (PLANSAB). The treated effluent from ETE JATAI is discharged into local water bodies that ultimately drain into the Paraná River basin, one of South America's major river systems. The receiving waters support diverse aquatic life and are important for regional agriculture and water supply. Proper treatment helps protect downstream ecosystems and water quality in the broader Paraná watershed.

ETE JATAI discharges into local streams that flow into the Claro River, a tributary of the Paranaíba River, which forms part of the upper Paraná River basin. This watershed supports diverse aquatic ecosystems, including fish species important for local fisheries. The region's tropical climate with distinct wet and dry seasons influences flow patterns and pollutant dilution capacity. Protecting water quality in this basin is critical for downstream communities and the ecologically sensitive Paraná River floodplain.
