ETE GRAO MOGOL Wastewater Treatment Plant, Grão Mogol, Minas Gerais

ETE GRAO MOGOL is a wastewater treatment plant located in Grão Mogol, a municipality in the state of Minas Gerais, Brazil. The plant serves a population of approximately 3,318 residents, classifying it as a small-scale facility within the region's sanitation infrastructure. It operates under Brazil's national environmental regulations, which mandate secondary treatment for urban wastewater to reduce organic load and protect water quality. The plant employs secondary treatment processes, which typically involve biological degradation of organic matter followed by sedimentation. Secondary treatment is the standard for municipal plants in Brazil, ensuring compliance with federal discharge standards set by CONAMA (National Environment Council). The plant's discharge volume is recorded at 245.38 (unit unspecified), indicating the scale of effluent managed daily. The treated effluent is discharged into local water bodies within the Jequitinhonha River basin, which ultimately flows into the Atlantic Ocean. The region's semi-arid climate and seasonal rainfall patterns make water quality management critical for sustaining aquatic ecosystems and downstream communities. The plant plays a key role in preventing untreated sewage from entering rivers, thereby protecting biodiversity and public health in the Jequitinhonha watershed.

The plant discharges into the Jequitinhonha River basin, a major watershed in eastern Brazil that flows into the Atlantic Ocean near Belmonte, Bahia. This basin supports diverse aquatic life and is important for local fisheries and agriculture. The semi-arid climate of northern Minas Gerais means that maintaining water quality is essential for ecosystem health, especially during dry periods when dilution capacity is limited.
