Overview
ETE VILA DA BARRA III is a secondary wastewater treatment plant in Manaus, Amazonas, Brazil, serving 325 people with a discharge volume of 38.97 cubic meters per day.
ETE VILA DA BARRA III is a wastewater treatment plant located in Manaus, the capital of Amazonas state in Brazil's North Region. Serving a small population of 325 people, it is part of the municipal infrastructure in the heart of the Amazon rainforest. The plant provides secondary treatment, which is a biological process that removes organic matter and suspended solids. Brazil's national environmental standards, under CONAMA Resolution 430/2011, require secondary treatment for most urban wastewater discharges. The plant's discharge volume of 38.97 cubic meters per day reflects its small scale. The treated effluent is discharged into local waterways that ultimately drain into the Amazon River basin, the largest river system in the world. The surrounding Amazon rainforest is ecologically sensitive, supporting immense biodiversity and playing a critical role in global carbon and water cycles. Proper wastewater treatment is essential to protect these vital ecosystems from nutrient pollution and pathogens.
Environmental context
The plant discharges into tributaries of the Amazon River, which flows through the Amazon basin into the Atlantic Ocean. The region's aquatic ecosystems support diverse fish species, including migratory catfish, and are critical for maintaining water quality in the world's largest tropical rainforest. Nutrient loading from untreated sewage could lead to eutrophication and harm aquatic life, making secondary treatment important for local environmental health.
