Overview
ETE INDAIA is a wastewater treatment plant in Caraguatatuba, São Paulo, Brazil, serving approximately 14,599 people. It lies within 50 km of the coast, discharging into the local watershed.
ETE INDAIA is a wastewater treatment plant located in Caraguatatuba, a coastal city in the state of São Paulo, Brazil. The plant serves a population of around 14,599, placing it in the medium agglomeration category under Brazilian regulations. It is situated in the Região Metropolitana do Vale do Paraíba e Litoral Norte, an area characterized by Atlantic Forest and coastal ecosystems. As a plant of this scale in Brazil, ETE INDAIA is subject to federal environmental standards (CONAMA resolutions) and state-level permitting by CETESB, São Paulo's environmental agency. Brazilian regulations typically require secondary treatment for municipal wastewater, with tertiary treatment in sensitive areas. The treated effluent from ETE INDAIA likely discharges into local water bodies that drain into the Atlantic Ocean, given the plant's proximity to the coast. The region's watershed supports diverse aquatic life and is part of the Atlantic Forest biome, a globally significant biodiversity hotspot. Proper treatment is essential to protect downstream ecosystems and coastal water quality.
Environmental context
The plant is located in the coastal watershed of São Paulo, with its treated effluent likely flowing into rivers such as the Rio do Ouro or nearby streams before reaching the Atlantic Ocean. The region's Atlantic Forest biome is ecologically sensitive, supporting high biodiversity and endemic species. Downstream coastal areas include mangroves and estuaries that serve as critical nursery habitats for marine life. Effective wastewater treatment is vital to prevent nutrient loading and contamination that could harm these fragile ecosystems.
