ETE JANAUBA Wastewater Treatment Plant, Janaúba, Minas Gerais, Brazil

ETE JANAUBA is a municipal wastewater treatment plant located in Janaúba, a city in the northern region of Minas Gerais, Brazil. The plant serves a population of around 17,365 residents, placing it in the small-to-medium agglomeration category. It is situated inland, far from the coast, and discharges into local water bodies that ultimately drain into the São Francisco River basin. As a Brazilian wastewater facility, ETE JANAUBA is subject to CONAMA Resolution 430/2011 and state-level environmental standards, which set effluent quality parameters for organic matter, solids, and nutrients. For a plant of this scale, secondary treatment is typically required to meet discharge limits. The regulatory framework ensures that appropriate treatment levels are maintained. The treated effluent from ETE JANAUBA is discharged into a receiving water body that flows into the São Francisco River, one of Brazil's most important waterways. The São Francisco River supports diverse aquatic ecosystems and provides water for agriculture, industry, and human consumption. Proper treatment at this plant helps protect downstream water quality and ecological health in the semi-arid region of northern Minas Gerais.

ETE JANAUBA discharges into a tributary of the São Francisco River, which flows northward through the Brazilian semi-arid region before reaching the Atlantic Ocean. The São Francisco River basin is ecologically significant, supporting diverse fish species and providing critical water resources in a drought-prone area. The plant's treatment performance directly affects downstream water quality, particularly in terms of nutrient loading and organic pollution, which can impact aquatic life and local communities that rely on the river.
