ETE Nova Vitoria ETE I - Secondary Wastewater Treatment Plant in Manaus, Amazonas, Brazil

ETE Nova Vitoria ETE I is a wastewater treatment plant located in Manaus, the capital of Amazonas state in northern Brazil. Serving a population of 542, this facility is part of the municipal sanitation infrastructure for the city, which lies at the confluence of the Negro and Solimões rivers, forming the Amazon River. The plant operates with secondary treatment, a standard level for smaller communities in Brazil. Brazil's wastewater sector is regulated by the National Environment Council (CONAMA) and the Ministry of Cities, with discharge standards set by CONAMA Resolution 430/2011. For secondary treatment plants like this one, typical processes include biological treatment followed by sedimentation, achieving removal of organic matter and suspended solids. The plant's discharge volume of 64.95 cubic meters per day reflects its small scale. The treated effluent is released into local waterways that drain into the Amazon River basin, the world's largest river system by discharge. This region hosts immense biodiversity, including floodplain forests and aquatic species. Proper treatment is crucial to prevent nutrient loading and protect downstream ecosystems, including the Amazon estuary and Atlantic Ocean.

The plant discharges into tributaries of the Amazon River, which flows through the Amazon rainforest before reaching the Atlantic Ocean. This watershed supports critical habitats for fish, reptiles, and migratory birds. Secondary treatment reduces organic pollutants, helping maintain water quality in a region sensitive to eutrophication and deforestation impacts.
