ETE Coronel Murta - Secondary Wastewater Treatment Plant in Coronel Murta, Minas Gerais

ETE Coronel Murta is a municipal wastewater treatment plant located in Coronel Murta, a town in the Jequitinhonha Valley region of Minas Gerais, Brazil. The plant serves a population of approximately 4,222 residents, placing it in the small agglomeration category under Brazilian regulatory frameworks. The plant provides secondary treatment, which is the minimum standard required under Brazilian environmental regulations (CONAMA Resolution 430/2011) for most inland water bodies. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into local watercourses that eventually drain into the Jequitinhonha River basin. This river flows eastward to the Atlantic Ocean, supporting diverse aquatic life and providing water for communities downstream. The plant's operation helps protect water quality in this semi-arid region where water resources are particularly valuable.

The plant discharges into the Jequitinhonha River basin, a major watershed in eastern Brazil that flows into the Atlantic Ocean near Belmonte, Bahia. The Jequitinhonha River supports a variety of fish species and is an important water source for local communities and agriculture. The region's semi-arid climate makes water quality management critical for maintaining ecosystem health and human water security.
