ETE MONTALVANIA - Secondary Wastewater Treatment Plant in Montalvânia, Minas Gerais

ETE MONTALVANIA is a wastewater treatment plant located in Montalvânia, a municipality in the state of Minas Gerais, Brazil. The plant provides secondary treatment for a small population of 109 residents, reflecting its role in a rural or small community setting. As part of Brazil's wastewater infrastructure, it contributes to local sanitation and environmental protection. The plant operates with secondary treatment, which typically involves biological processes to reduce organic matter and suspended solids. With a daily discharge volume of 8.64 cubic meters, the facility is sized for the small population it serves. In Brazil, wastewater treatment plants are regulated under national environmental standards, including CONAMA resolutions, which set effluent quality requirements for different treatment levels and receiving water bodies. The treated effluent from ETE MONTALVANIA is discharged into a local watercourse, likely a small river or stream within the São Francisco River basin, which is a major river system in eastern Brazil. The São Francisco River flows northward through the semi-arid region of Minas Gerais and Bahia, eventually reaching the Atlantic Ocean. The plant's operation helps protect downstream water quality and aquatic ecosystems in this important basin.

The plant discharges into a tributary of the São Francisco River, one of Brazil's most important watercourses, which flows through the semi-arid Caatinga biome and supports diverse aquatic life, including migratory fish species. The downstream environment includes the São Francisco River basin, which ultimately drains into the Atlantic Ocean. The region's seasonal rainfall patterns and water scarcity make effective wastewater treatment critical for maintaining water quality and ecological balance.
