Overview
ETE CIDADAO IX ETE I is a secondary treatment plant serving 1,739 people in Manaus, Amazonas, Brazil. It discharges 208.50 cubic meters of treated wastewater, operating under Brazil's national environmental regulations.
ETE CIDADAO IX ETE I is a wastewater treatment facility located in Manaus, the capital of Amazonas state in northern Brazil. The plant serves a population of 1,739 people, classifying it as a small-scale municipal treatment facility within the urban fabric of Manaus. The plant provides secondary treatment, which is the standard biological treatment stage required under Brazil's National Environment Council (CONAMA) resolutions for urban wastewater. Secondary treatment typically involves biological degradation of organic matter, reducing biochemical oxygen demand and suspended solids before discharge. The treated effluent is discharged into local waterways that drain into the Amazon River basin, one of the world's largest and most biodiverse freshwater systems. The plant's operation helps protect downstream aquatic ecosystems and communities from untreated sewage, supporting water quality in the Amazon region.
Environmental context
The plant discharges into tributaries of the Amazon River, which flows through the Amazon rainforest and ultimately empties into the Atlantic Ocean. The Amazon basin supports immense biodiversity, including thousands of fish species and aquatic mammals. Proper wastewater treatment is critical to prevent nutrient pollution and pathogen contamination in this ecologically sensitive watershed.
