ETE Ibotirama is a municipal wastewater treatment plant located in Ibotirama, Bahia, Brazil. It serves a population of approximately 4,684 residents, making it a small-scale facility within the region's sanitation infrastructure. The plant is situated in the northeastern region of Brazil, an area characterized by semi-arid climate and seasonal rainfall patterns. The plant provides secondary treatment, which is a biological process that removes organic matter and suspended solids. For a community of this size, secondary treatment meets the typical standards for environmental protection in Brazil. The plant operates under Brazil's national environmental regulations, which are enforced by state agencies such as the Instituto do Meio Ambiente e Recursos Hídricos (INEMA) in Bahia. The treated effluent is discharged into local water bodies that ultimately drain into the São Francisco River, one of Brazil's most important waterways. The São Francisco River basin supports diverse aquatic life and provides water for agriculture, industry, and human consumption. Proper treatment at ETE Ibotirama helps protect downstream water quality and the ecological health of the basin.

The plant discharges into the São Francisco River basin, which flows through the semi-arid Caatinga biome before reaching the Atlantic Ocean. The river supports a variety of fish species and is a critical water source for millions of people. Secondary treatment helps reduce organic pollution, protecting downstream ecosystems and water quality for communities along the river.
