ETE IGARATA is a municipal wastewater treatment facility located in Igaratá, a city in the state of São Paulo, Brazil. The plant serves a population of approximately 2,230 residents, reflecting its role in managing domestic wastewater for a small community within the Vale do Paraíba region. The plant employs secondary treatment, which is the standard biological process for removing organic matter and suspended solids. Under Brazil's national environmental regulations (CONAMA resolutions), secondary treatment is typically required for communities of this size to meet effluent quality standards before discharge. The plant treats an average daily flow of 474.62 cubic meters. The treated effluent is discharged into local water bodies that ultimately drain into the Paraíba do Sul River basin, a major river system in southeastern Brazil. This river supplies water to millions of people and supports diverse aquatic ecosystems. Proper treatment at ETE IGARATA helps protect downstream water quality and public health.
Environmental context
The plant's discharge enters the Paraíba do Sul River basin, which flows through the states of São Paulo, Rio de Janeiro, and Minas Gerais before reaching the Atlantic Ocean near Campos dos Goytacazes. The river is a critical water source for the metropolitan region of Rio de Janeiro. The watershed supports diverse aquatic life and is an important migratory corridor for fish species. Protecting this river from untreated sewage is essential for maintaining ecological balance and water quality for downstream communities.
