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

ETE Matozinhos is a wastewater treatment plant located in the Floresta neighborhood of Matozinhos, in the state of Minas Gerais, Brazil. The plant serves a small population of 382 residents within the Região Metropolitana de Belo Horizonte, an area characterized by urban and industrial development. As a secondary treatment facility, it provides biological treatment to reduce organic pollutants and suspended solids before discharge. The plant operates under Brazil's national environmental regulations, which require secondary treatment for urban wastewater. The plant's discharge volume of 55.85 cubic meters indicates a scale appropriate for its small service population. Brazilian legislation, such as CONAMA Resolution 430/2011, sets effluent standards for wastewater treatment plants to protect water resources. The treated effluent from ETE Matozinhos is discharged into local water bodies that eventually flow into the Rio das Velhas, a major tributary of the São Francisco River basin. The São Francisco River is one of Brazil's most important waterways, supporting agriculture, hydropower, and biodiversity. Proper treatment at this plant helps reduce nutrient and pathogen loads, contributing to the ecological health of downstream aquatic ecosystems.

The plant discharges into local streams that drain into the Rio das Velhas, a key tributary of the São Francisco River basin. The São Francisco River supports diverse aquatic life and provides water for millions of people. Secondary treatment at ETE Matozinhos helps control organic pollution and nutrient loading, which is critical for maintaining water quality in this ecologically sensitive watershed.
