ETE DORES DO INDAIA Wastewater Treatment Plant, Dores do Indaiá, Minas Gerais, Brazil

ETE DORES DO INDAIA is a municipal wastewater treatment plant located in Dores do Indaiá, a city in the state of Minas Gerais, Brazil. The plant serves a population of around 11,457 residents, placing it in the small to medium agglomeration category. It is situated in the southeastern region of Brazil, an area characterized by a tropical climate and significant agricultural activity. As a Brazilian wastewater facility, ETE DORES DO INDAIA is subject to the national regulatory framework established by the National Environment Council (CONAMA) and the Ministry of Cities. For agglomerations of this scale, secondary treatment is typically required to meet effluent standards for organic matter and suspended solids. The plant's operational context aligns with Brazil's goal of expanding sanitation coverage under the National Sanitation Plan (PLANSAB). The plant discharges treated effluent into local water bodies that drain into the São Francisco River basin, one of Brazil's most important river systems. The São Francisco River flows northeastward through the semi-arid region before reaching the Atlantic Ocean. The downstream environment supports diverse aquatic life and provides water for irrigation and human consumption, making proper treatment essential for ecological and public health.

The treated effluent from ETE DORES DO INDAIA ultimately enters the São Francisco River basin, a major watershed that drains into the Atlantic Ocean. The São Francisco River is a vital water source for northeastern Brazil, supporting agriculture, fisheries, and biodiversity. The plant's discharge contributes to the river's flow, and effective treatment is crucial to prevent nutrient pollution and protect downstream aquatic ecosystems.
