ETE ITABERABA Wastewater Treatment Plant, Itaberaba, Bahia, Brazil

ETE ITABERABA is a wastewater treatment plant located in the Nova América neighborhood of Itaberaba, in the state of Bahia, Brazil. The plant serves a population of around 40,428 residents, placing it in the medium-agglomeration category for Brazilian wastewater infrastructure. As a facility in Brazil, ETE ITABERABA is subject to the country's environmental regulations, including CONAMA resolutions and state-level water quality standards. For a plant of this scale, secondary treatment is typically required to reduce organic load and suspended solids before discharge. The plant's treatment process and capacity details are not publicly available, but it is expected to meet the standards set by the National Environment Council (CONAMA) for inland water bodies. The plant discharges treated effluent into local watercourses that drain into the Paraguaçu River basin, which flows into the Baía de Todos os Santos (All Saints Bay) on the Atlantic coast. This watershed supports diverse aquatic life and provides water for agriculture and communities downstream. Proper treatment is essential to protect water quality and ecosystem health in the region.

ETE ITABERABA discharges into the Paraguaçu River basin, which flows into Baía de Todos os Santos, a large tropical bay on Brazil's northeastern coast. The bay is an ecologically significant estuary supporting mangroves, seagrass beds, and diverse marine species. The plant's location inland, over 50 km from the coast, reduces direct marine impact, but its effluent contributes to the freshwater flow that sustains the bay's brackish habitats. Effective treatment is critical to prevent nutrient loading and maintain water quality in this sensitive coastal ecosystem.
