ETE Morada Bela Wastewater Treatment Plant, Salvador, Bahia

ETE Morada Bela is a wastewater treatment plant located in the Jardim Cajazeiras neighborhood of Salvador, the capital of Bahia state in northeastern Brazil. The plant serves a small population of 366 residents, reflecting its role as a local facility within the broader Salvador metropolitan region. The plant provides 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 the minimum requirement for most municipal wastewater discharges. The plant's discharge volume of 39.56 m³/day indicates a small-scale operation consistent with the population served. Situated less than 10 km from the Atlantic coast, the plant's treated effluent likely drains into local watercourses that flow into the Baía de Todos os Santos, one of Brazil's largest and most ecologically significant bays. This coastal environment supports diverse marine life, including mangroves and coral reefs, making proper treatment essential for protecting downstream ecosystems.

The plant is located within the drainage basin of Baía de Todos os Santos, a large tropical bay that receives freshwater from several rivers including the Rio Paraguaçu and Rio Subaé. The bay supports extensive mangrove forests, seagrass beds, and coral formations, providing critical habitat for fish, crustaceans, and migratory birds. As a coastal facility, ETE Morada Bela's secondary treatment helps reduce nutrient and pathogen loads entering this sensitive marine environment.
