ETE DOS SALTOS Wastewater Treatment Plant, Juara, Mato Grosso, Brazil

ETE DOS SALTOS is a municipal wastewater treatment plant located in Juara, Mato Grosso, Brazil. Serving a population of approximately 13,010 people, the plant is part of the region's sanitation infrastructure in the Central-West region, an area characterized by the Amazon rainforest and Cerrado biomes. Brazil's wastewater treatment standards are governed by federal regulations, including CONAMA resolutions and the National Sanitation Plan (PLANSAB). For agglomerations of this size, secondary treatment is typically required to meet effluent quality standards. The plant's operational details are managed within the municipal framework, ensuring compliance with environmental discharge criteria. The plant discharges treated effluent into local water bodies that drain into the Amazon River basin, ultimately reaching the Atlantic Ocean. This watershed supports diverse aquatic ecosystems, including fish species and riparian habitats, making effective treatment critical for downstream ecological health.

The plant's treated effluent flows into tributaries of the Amazon River basin, one of the world's largest and most biodiverse freshwater systems. The receiving waters support a wide range of aquatic life, including migratory fish and freshwater dolphins. Proper treatment is essential to prevent nutrient loading and contamination that could harm downstream ecosystems in the Amazon floodplains.
