ETE Bananal SP - Secondary Wastewater Treatment Plant in Bananal, São Paulo

ETE Bananal SP is a municipal wastewater treatment plant located in Bananal, a city in the state of São Paulo, Brazil. The plant provides secondary treatment for a population of approximately 7,084 residents, contributing to the region's sanitation infrastructure within the Metropolitan Region of Vale do Paraíba e Litoral Norte. As a secondary treatment facility, ETE Bananal SP meets the standard treatment requirements for Brazilian municipalities of this scale. Under Brazil's national sanitation framework, secondary treatment is the typical minimum for urban wastewater, ensuring removal of organic matter and suspended solids before discharge. The plant's reported discharge volume of 895.03 cubic meters per day indicates its operational scale. The treated effluent from ETE Bananal SP is discharged into local watercourses that ultimately drain into the Paraíba do Sul River, a major river system in southeastern Brazil. The Paraíba do Sul basin supports diverse aquatic ecosystems and provides water for multiple municipalities downstream. The plant's secondary treatment helps protect water quality in this ecologically important watershed.

The plant discharges into tributaries of the Paraíba do Sul River, which flows through the states of São Paulo, Rio de Janeiro, and Minas Gerais before reaching the Atlantic Ocean near Campos dos Goytacazes. The basin supports diverse aquatic life and is a critical water source for millions of people. Secondary treatment reduces organic pollution, helping maintain ecological balance in the river system.
