ETE Taubaté-Tremembé is a municipal wastewater treatment plant located in Tremembé, within the Metropolitan Region of Vale do Paraíba e Litoral Norte, São Paulo, Brazil. Serving a population of about 238,000, it is a large-scale facility that plays a key role in managing wastewater from the urbanized Paraíba Valley region. As a Brazilian wastewater treatment plant serving a population over 200,000, it falls under national regulations such as CONAMA Resolution 430/2011 and the National Water Resources Policy (Law 9.433/1997). These regulations require adequate treatment to protect water quality, typically including secondary or advanced treatment for large agglomerations. The plant's treated effluent is discharged into the Paraíba do Sul River basin, which flows through the states of São Paulo, Rio de Janeiro, and Minas Gerais. This river is vital for water supply, agriculture, and industry, and supports diverse aquatic ecosystems. The basin ultimately drains into the Atlantic Ocean near Campos dos Goytacazes, Rio de Janeiro.
Environmental context

The river supports important ecosystems, including riparian forests and wetlands, and provides water for millions of people. Downstream, the river's estuary and coastal zone are ecologically sensitive areas that depend on good water quality for biodiversity and fisheries.
