Overview
ETE Sao Miguel serves 62,112 residents in Sao Paulo's eastern zone. The plant discharges into the Tiete River basin, which flows through the metropolitan region before reaching the Parana River system.
ETE Sao Miguel is a municipal wastewater treatment plant located in the Vila Pantanal neighborhood of Sao Miguel Paulista, in the eastern part of Sao Paulo, Brazil. Serving a population of approximately 62,112 people, the plant is part of the city's extensive sanitation infrastructure managed by Sabesp, the state-owned water and wastewater company. Brazil's wastewater treatment standards are governed by CONAMA Resolution 430/2011 and state-level regulations. For a plant of this scale, secondary treatment is typically required to reduce organic load and suspended solids before discharge. It operates within the regulatory framework of Sao Paulo state's environmental agency (CETESB). The plant's treated effluent is discharged into local watercourses that drain into the Tiete River, a major waterway crossing the Sao Paulo metropolitan region. The Tiete River flows westward, eventually joining the Parana River system, which is vital for water supply, agriculture, and hydropower in southeastern Brazil. The watershed faces significant urban pollution challenges, and the plant plays a key role in reducing the environmental impact of the densely populated area.
Environmental context
The plant discharges into the Tiete River basin, which flows through the Sao Paulo metropolitan region and ultimately reaches the Parana River, one of South America's largest river systems. The Tiete River is heavily impacted by urban runoff and industrial discharges, making wastewater treatment critical for improving water quality and protecting downstream ecosystems, including the Parana River floodplain and its diverse aquatic life.
