Overview
ETE Estoril Taubaté serves approximately 13,228 residents in Taubaté, São Paulo, Brazil. The plant discharges treated wastewater into the local watershed within the Paraíba do Sul River basin.
ETE Estoril Taubaté is a municipal wastewater treatment plant located in the Residencial Estoril neighborhood of Taubaté, in the state of São Paulo, Brazil. The plant serves a population of about 13,228 people, placing it in the small-to-medium agglomeration category. It operates within the densely populated Paraíba Valley region, an area with significant industrial and urban activity. As a Brazilian wastewater facility, ETE Estoril Taubaté is subject to national regulations under CONAMA resolutions and state-level environmental licensing by CETESB. For agglomerations of this scale, secondary treatment is typically required to meet effluent standards. It is expected to comply with discharge limits set by the permitting authority. The treated effluent from the plant ultimately drains into the Paraíba do Sul River, a major watercourse that flows through the states of São Paulo, Rio de Janeiro, and Minas Gerais before reaching the Atlantic Ocean near Campos dos Goytacazes. The river supports diverse aquatic life and provides water for millions of people downstream, making proper treatment essential for protecting water quality and ecosystem health.
Environmental context
The plant's discharge enters the local drainage network that feeds into the Paraíba do Sul River, one of Brazil's most important rivers. The river flows through the Vale do Paraíba region and empties into the Atlantic Ocean. The watershed supports diverse aquatic habitats and is a critical water source for agriculture, industry, and drinking water supply. Protecting this river from nutrient pollution and pathogens is vital for maintaining downstream ecological balance and public health.
