ETE Caxambu Wastewater Treatment Plant, Caxambu, Minas Gerais

ETE Caxambu is a wastewater treatment facility located in Caxambu, a city in the state of Minas Gerais, Brazil. The plant serves a population of around 20,694 residents, placing it in the medium agglomeration category for Brazilian wastewater infrastructure. It is situated in the southeastern region of the country, an area characterized by mountainous terrain and a subtropical climate. As a Brazilian wastewater treatment plant, ETE Caxambu is subject to the national regulatory framework established by the National Environment Council (CONAMA) and the Ministry of Cities. For agglomerations of this size, Brazilian standards typically require secondary treatment to reduce organic load and protect receiving water bodies. The plant's design and operational standards align with these national guidelines, ensuring compliance with effluent quality parameters. The plant discharges treated wastewater into local watercourses that are part of the Rio Grande basin, which ultimately flows into the Paraná River system. This watershed supports diverse aquatic life and provides water for agriculture and human consumption downstream. Proper treatment at ETE Caxambu helps maintain water quality in the region's rivers and contributes to the ecological health of the broader Paraná basin.

The treated effluent from ETE Caxambu enters local streams that feed into the Rio Grande, a major tributary of the Paraná River system. The Paraná basin is one of South America's largest watersheds, supporting extensive biodiversity and providing water for millions of people. The region's aquatic ecosystems are sensitive to nutrient pollution and organic loading, making effective wastewater treatment critical for preserving water quality and habitat integrity.
