ETE Mirante Brumadinho - Secondary Wastewater Treatment in Brumadinho, Minas Gerais

ETE Mirante Brumadinho is a wastewater treatment plant located in the Retiro das Pedras area of Brumadinho, in the state of Minas Gerais, Brazil. The plant serves a small population of 1,782 residents within the Metropolitan Region of Belo Horizonte, one of Brazil's most populous urban agglomerations. As a secondary treatment facility, it provides biological treatment to reduce organic pollutants and suspended solids before discharge. The plant operates under Brazil's national environmental regulations, which are enforced by state environmental agencies such as FEAM (Fundação Estadual do Meio Ambiente) in Minas Gerais. For small agglomerations like Brumadinho, secondary treatment is the standard requirement to protect receiving water bodies. The plant's discharge volume of 165.02 cubic meters indicates a modest flow consistent with its population served. Treated effluent from ETE Mirante Brumadinho is discharged into local waterways that drain into the Paraopeba River, a major tributary of the São Francisco River basin. The São Francisco River is one of Brazil's most important watercourses, supporting agriculture, hydropower, and biodiversity in the semi-arid Northeast. Proper treatment at this plant helps protect downstream water quality and aquatic ecosystems.

The plant's discharge enters the Paraopeba River basin, which flows into the São Francisco River, a vital waterway for Brazil's semi-arid region. The São Francisco River supports diverse aquatic life, including migratory fish species, and provides water for irrigation and human consumption. The plant's secondary treatment reduces organic load and nutrients, helping to prevent eutrophication and maintain ecological balance in downstream waters.
