ETE Morada Nova de Minas - Secondary Wastewater Treatment in Minas Gerais, Brazil

ETE Morada Nova de Minas is a municipal wastewater treatment facility located in Morada Nova de Minas, a city in the state of Minas Gerais, Brazil. The plant serves a population of approximately 1,657 residents, reflecting its role in managing domestic wastewater for a small community in the southeastern region of the country. The plant provides secondary treatment, a standard level required under Brazilian regulations (CONAMA resolutions) for inland water bodies. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant discharges 216.45 m³/day of treated wastewater, indicating a modest operational scale consistent with the population served. The treated effluent is discharged 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 northward through the semi-arid sertão and ultimately reaches the Atlantic Ocean. The plant's operation helps protect downstream water quality in this ecologically and economically vital basin, supporting aquatic life and human uses such as agriculture and drinking water supply.

The plant discharges into local streams that are part of the São Francisco River basin, which flows through the states of Minas Gerais, Bahia, Pernambuco, Alagoas, and Sergipe before reaching the Atlantic Ocean. The basin supports diverse aquatic ecosystems, including migratory fish species and riparian forests. As a coastal-proximate facility (within 10 km of the coast), the plant's secondary treatment helps reduce nutrient and organic loads that could otherwise contribute to eutrophication in downstream reservoirs and coastal zones.
