ETE Gentio do Ouro is a municipal wastewater treatment plant located in Gentio do Ouro, a municipality in the state of Bahia, Brazil. The plant serves a population of 3,381 residents, classifying it as a small-scale facility under Brazilian sanitation standards. It operates as part of the regional infrastructure for the Capim-grosso area within the Região Geográfica Imediata de Xique-Xique - Barra. The plant provides secondary treatment, which is the standard level required by Brazilian regulations (CONAMA Resolution 430/2011) for inland water bodies. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant's discharge volume of 273.99 cubic meters per day aligns with the population served. Brazilian legislation mandates that treatment plants of this scale meet effluent quality standards to protect receiving waters. The treated effluent is discharged into a local watercourse that ultimately drains into the São Francisco River basin, one of Brazil's most important river systems. The São Francisco River flows through the semi-arid region of Bahia and provides water for agriculture, drinking, and hydropower. The plant's operation helps protect downstream water quality in this ecologically sensitive basin, which supports diverse aquatic life and is a critical resource for the region.
Environmental context
The plant discharges into a tributary of the São Francisco River basin, which flows through the semi-arid Caatinga biome in Bahia. The São Francisco River is a major water source for northeastern Brazil, supporting irrigation, fisheries, and biodiversity. Downstream, the river eventually reaches the Atlantic Ocean. The plant's secondary treatment reduces organic pollution, helping to maintain water quality in a region where water resources are scarce and ecologically important.
