ETE Francisco Dumont - Secondary Wastewater Treatment Plant in Francisco Dumont, Minas Gerais

ETE Francisco Dumont is a municipal wastewater treatment plant located in Francisco Dumont, a town in the northern region of Minas Gerais, Brazil. The plant serves a small population of 778 residents, reflecting the scale of the local community. It operates as a secondary treatment facility, which is appropriate for the population size and typical for smaller agglomerations in Brazil. As a secondary treatment plant, ETE Francisco Dumont provides biological treatment to remove organic matter and suspended solids. The plant discharges 56.16 m³/day of treated wastewater. In Brazil, wastewater treatment plants are regulated under federal environmental laws, including CONAMA resolutions, which set discharge standards for treated effluent. For plants of this scale, secondary treatment is the standard requirement to protect receiving water bodies. The treated effluent from ETE Francisco Dumont is discharged into local watercourses that drain into the São Francisco River basin, one of Brazil's most important river systems. The São Francisco River flows northward through the semi-arid region of Minas Gerais and Bahia, eventually reaching the Atlantic Ocean. The plant plays a key role in protecting local water quality and downstream ecosystems in this ecologically sensitive region.

The plant discharges into local streams that are part of the São Francisco River basin, which drains a vast area of eastern Brazil. The São Francisco River supports diverse aquatic life and provides water for agriculture, industry, and human consumption. Downstream, the river flows through the semi-arid Caatinga biome, where water resources are critical for local communities and biodiversity. The plant's secondary treatment helps reduce nutrient and organic pollution, protecting the ecological health of the river system.
