ETE JARDINS MANGABEIRA - Secondary Wastewater Treatment in Salvador, Bahia

ETE JARDINS MANGABEIRA is a wastewater treatment plant located in the Cajazeiras neighborhood of Salvador, Bahia, Brazil. It serves a population of approximately 4,833 residents, classifying it as a small-scale facility within the metropolitan region of Salvador. The plant provides secondary treatment, which is the standard biological process required for municipal wastewater in Brazil under national regulations. Secondary treatment typically involves biological degradation of organic matter followed by sedimentation. The plant discharges an average of 522.30 m³/day of treated effluent. Situated within 10 km of the Atlantic coast, the plant's discharge ultimately reaches the Bay of All Saints (Baía de Todos os Santos), a large tropical bay that supports diverse marine life and is an important ecological and economic resource for the region. The plant's operation helps protect local water quality and coastal ecosystems.

The plant discharges treated effluent into the local drainage system that flows into the Bay of All Saints, a large estuarine bay on the Atlantic coast of Bahia. This bay supports mangroves, seagrass beds, and coral reefs, providing critical habitat for fish, crustaceans, and migratory birds. The plant's secondary treatment reduces organic load and helps maintain water quality in this ecologically sensitive coastal environment.
