ETE TRES MARIAS is a wastewater treatment plant located in Três Marias, a city in the state of Minas Gerais, Brazil. The plant serves a population of about 22,688, placing it in the medium agglomeration category under Brazilian regulatory frameworks. It is situated inland, far from the coast, and its operations are part of the regional sanitation infrastructure managed by local authorities. Plants of this scale in Brazil typically employ secondary treatment technologies such as activated sludge or stabilization ponds, in compliance with national environmental standards (CONAMA resolutions). The designed capacity of 1.00 suggests a relatively small facility, likely focused on municipal wastewater treatment for the local community. The treated effluent is discharged into a receiving water body within the São Francisco River basin, one of Brazil's major river systems. The downstream environment includes the Três Marias Reservoir, a large artificial lake created by the Três Marias Dam, which supports diverse aquatic life and is important for regional water supply, irrigation, and hydroelectric power generation. The plant plays a key role in protecting water quality in this ecologically sensitive area.
Environmental context
The plant discharges into a tributary of the São Francisco River, which flows into the Três Marias Reservoir. This reservoir is a critical water resource for the region, supporting aquatic biodiversity and providing water for human consumption, agriculture, and industry. The downstream environment includes the São Francisco River basin, which drains into the Atlantic Ocean. Protecting water quality in this watershed is essential for maintaining the ecological health of the reservoir and the river, which are home to various fish species and other aquatic organisms.
