Overview
ETE Ilhéus is a municipal wastewater treatment plant serving approximately 89,000 people in Ilhéus, Bahia, Brazil. It is located near the coast in the Northeast Region.
ETE Ilhéus is a municipal wastewater treatment plant located in Ilhéus, Bahia, Brazil, serving an estimated population of 89,324. The plant is situated in the Pontal district near the Jorge Amado bridge, within the coastal zone of the Northeast Region. As a facility serving a medium-sized agglomeration, it plays a key role in managing wastewater for this urban area. Brazil's wastewater treatment sector is regulated by federal standards such as CONAMA resolutions and state-level environmental agencies. For plants of this scale, secondary treatment is typically required to reduce organic load and pathogens before discharge. The plant's designed capacity is 1. The plant discharges treated effluent into local water bodies that ultimately flow into the Atlantic Ocean, given its proximity to the coast. The region's watershed includes rivers draining the Atlantic Forest biome, which supports diverse aquatic life and mangroves. Proper treatment is essential to protect downstream ecosystems and coastal water quality.
Environmental context
ETE Ilhéus is located near the coast of Bahia, within the drainage basin of rivers that flow into the Atlantic Ocean. The receiving water bodies are part of the Atlantic Forest biome, an ecologically sensitive region with high biodiversity. Treated effluent from the plant must meet standards to protect downstream mangroves, estuaries, and marine habitats from nutrient pollution and pathogens.
