ETE Ibiaí Wastewater Treatment Plant, Ibiaí, Minas Gerais, Brazil

ETE Ibiaí is a wastewater treatment plant located in Ibiaí, a municipality in the state of Minas Gerais, Brazil. The plant serves a population of approximately 2,293 residents, providing essential sanitation infrastructure for this inland community. As a secondary treatment facility, it plays a key role in reducing organic pollutants and suspended solids before discharge. The plant operates under Brazil's national environmental regulations, which mandate wastewater treatment for urban agglomerations. For a community of this size, secondary treatment is the standard requirement, ensuring compliance with federal water quality standards. The plant's discharge volume is recorded at 164.16 cubic meters, reflecting its operational scale. The treated effluent from ETE Ibiaí is released into local waterways that eventually drain into the São Francisco River basin, one of Brazil's most important river systems. This river supports diverse aquatic life and provides water for agriculture, industry, and drinking supplies downstream. By treating wastewater, the plant helps protect water quality in this ecologically significant basin.

ETE Ibiaí discharges treated wastewater into local streams that flow into the São Francisco River, a major watercourse traversing the Brazilian states of Minas Gerais, Bahia, and others before reaching the Atlantic Ocean. The São Francisco basin supports a rich diversity of fish species and is a critical water source for semi-arid regions. The plant's secondary treatment reduces organic load and nutrients, helping to prevent eutrophication and maintain the ecological health of downstream waters.
