ETE ONCA is a key wastewater treatment facility located in Belo Horizonte, the capital of Minas Gerais, Brazil. Situated in the northern region of the city, it serves a large population of around 755,000 residents, making it a critical component of the metropolitan area's sanitation network. The plant is part of the broader water management system for the Região Metropolitana de Belo Horizonte. As a large-scale treatment plant serving over 150,000 people, ETE ONCA operates under Brazil's national environmental regulations, which require appropriate treatment levels to protect water quality. Plants of this size typically employ secondary or advanced treatment to meet discharge standards. The facility is expected to comply with standards set by the Conselho Nacional do Meio Ambiente (CONAMA) and state-level environmental agencies. The treated effluent from ETE ONCA ultimately discharges into the Rio das Velhas basin, a major tributary of the São Francisco River. This river system is ecologically significant, supporting diverse aquatic life and providing water for downstream communities. Proper treatment at this plant is essential for maintaining water quality in the Rio das Velhas and protecting the broader São Francisco watershed.
Environmental context
ETE ONCA discharges into the Rio das Velhas, which flows into the São Francisco River, one of Brazil's most important waterways. The São Francisco River basin supports a wide range of ecosystems, including the Caatinga and Atlantic Forest biomes, and provides water for agriculture, industry, and millions of people. The plant's location in a densely populated urban area means its effluent quality directly affects downstream water resources and ecological health.
