ETE Carangola Wastewater Treatment Plant, Carangola, Minas Gerais, Brazil

ETE Carangola is a wastewater treatment plant located in Carangola, a city in the state of Minas Gerais, Brazil. The plant serves a population of approximately 3,432 people, making it a small-scale facility within the region's sanitation infrastructure. The plant provides secondary treatment, which is the standard biological treatment process that removes organic matter and suspended solids. For a small agglomeration of this size, secondary treatment meets the typical requirements under Brazilian regulations, which are aligned with international standards for environmental protection. The treated effluent is discharged into local water bodies that eventually drain into the Paraíba do Sul River basin, a major river system in southeastern Brazil. This river flows through the states of São Paulo, Rio de Janeiro, and Minas Gerais, ultimately reaching the Atlantic Ocean near Campos dos Goytacazes. The plant plays a role in protecting downstream water quality and aquatic ecosystems.

The plant discharges into the Paraíba do Sul River basin, which flows through the Atlantic Forest biome and supports diverse aquatic life. The river is a critical water source for millions of people and industries downstream. The treated effluent helps maintain water quality in this ecologically sensitive region, which is also important for migratory fish species.
