ETE Chiareta is a wastewater treatment plant located in Abrantes, Camaçari, within the Metropolitan Region of Salvador, Bahia, Brazil. The plant serves a small population of 211 residents and operates with secondary treatment, which is typical for small agglomerations in Brazil under national sanitation regulations. As a secondary treatment facility, ETE Chiareta removes organic matter and suspended solids through biological processes. The plant discharges 15.24 m³/day of treated effluent. Brazilian wastewater standards, set by CONAMA Resolution 430/2011, require secondary treatment for most inland and coastal discharges, with additional disinfection for bathing waters. The plant is situated within 10 km of the Atlantic coast, meaning its treated effluent likely drains into coastal waters near Salvador. This area supports diverse marine life and is part of the broader Todos os Santos Bay ecosystem, which is ecologically sensitive due to its mangroves and estuarine habitats.
Environmental context
The plant's discharge likely reaches the Atlantic Ocean via local drainage, potentially entering Todos os Santos Bay, a large tropical bay known for its mangroves, coral reefs, and rich biodiversity. The bay supports fisheries and is a critical habitat for migratory birds and marine species. Coastal discharge requires careful management to prevent nutrient enrichment and protect water quality.
