ETE Sarzedo - Secondary Wastewater Treatment Plant in Sarzedo, Minas Gerais

ETE Sarzedo is a municipal wastewater treatment plant located in Sarzedo, within the Metropolitan Region of Belo Horizonte, Minas Gerais, Brazil. The plant serves a small population of 1,811 residents, reflecting its role in a smaller urban community in southeastern Brazil. The plant provides secondary treatment, which is the standard biological treatment level required for municipal wastewater in Brazil under national regulations. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids, meeting basic environmental standards for discharge. Treated effluent from the plant is discharged into local water bodies within the Rio das Velhas basin, a tributary of the São Francisco River. The São Francisco River is one of Brazil's most important waterways, supporting diverse aquatic ecosystems and providing water for agriculture, industry, and communities downstream.

The plant discharges into the Rio das Velhas watershed, which flows into the São Francisco River, a major river system in eastern Brazil. The São Francisco River basin supports diverse aquatic life, including migratory fish species, and is ecologically sensitive due to its role in semi-arid regions. Proper wastewater treatment is critical to prevent nutrient pollution and protect downstream water quality.
