ETE SAFRA Wastewater Treatment Plant - Muriaé, Minas Gerais, Brazil

ETE SAFRA is a wastewater treatment plant located in the Santana neighborhood of Muriaé, a city in the Zona da Mata region of Minas Gerais, Brazil. The plant serves a population of about 13,629 residents, placing it in the small-to-medium agglomeration category for Brazilian wastewater infrastructure. Brazil's wastewater treatment regulations are established by the National Environment Council (CONAMA) and the Ministry of Cities, with oversight often delegated to state environmental agencies. For plants of this scale, secondary treatment is typically required to meet effluent standards for organic matter and suspended solids. The regulatory framework ensures compliance with national discharge standards. The plant discharges treated effluent into local water bodies that ultimately drain into the Paraíba do Sul River basin, one of Brazil's most important river systems. The Paraíba do Sul flows through the states of São Paulo, Rio de Janeiro, and Minas Gerais, providing water for millions of people and supporting diverse aquatic ecosystems. Proper treatment at ETE SAFRA helps protect downstream water quality and ecological health.

The treated effluent from ETE SAFRA likely enters a tributary of the Paraíba do Sul River, which flows through the Atlantic Forest biome. This river basin is critical for water supply and supports a variety of fish species and riparian habitats. The region's tropical climate and seasonal rainfall patterns influence dilution and assimilation capacity of receiving waters.
