ETE Morro Alto Wastewater Treatment Plant, Vespasiano, Minas Gerais

ETE Morro Alto is a wastewater treatment plant located in Vespasiano, within the Metropolitan Region of Belo Horizonte, Minas Gerais, Brazil. The plant serves a population of approximately 24,264 people, placing it in the medium agglomeration category under Brazilian regulatory frameworks. As part of the broader sanitation infrastructure for the Belo Horizonte metropolitan area, it plays a key role in managing domestic wastewater from this rapidly urbanizing region. Brazil's wastewater treatment standards are governed by federal regulations, including CONAMA Resolution 430/2011, which sets effluent quality standards for discharge into water bodies. For plants of this scale, secondary treatment is typically required to reduce organic load and suspended solids. The plant is expected to comply with these national standards to protect downstream water quality. The treated effluent from ETE Morro Alto is discharged into local watercourses that ultimately drain into the Rio das Velhas, a major tributary of the São Francisco River. The São Francisco River basin is ecologically significant, supporting diverse aquatic life and providing water for agriculture, industry, and human consumption. Proper treatment at this plant helps reduce nutrient and pollutant loads entering this important river system.

The plant discharges into local streams that flow into the Rio das Velhas, a key tributary of the São Francisco River. The São Francisco basin is one of Brazil's most important river systems, supporting diverse aquatic ecosystems and providing water for millions of people. Downstream, the river flows through semi-arid regions and eventually reaches the Atlantic Ocean. Effective wastewater treatment at ETE Morro Alto helps protect water quality in this ecologically and economically vital watershed.
