ETE Vivendas do Joanes - Secondary Wastewater Treatment Plant in Camaçari, Bahia

ETE Vivendas do Joanes is a wastewater treatment plant located in the Abrantes district of Camaçari, Bahia, Brazil. It serves a small population of 32 people and operates with secondary treatment, which is typical for small-scale facilities in the region. The plant is situated near the coast, within the Metropolitan Region of Salvador. As a secondary treatment plant, ETE Vivendas do Joanes provides biological treatment to reduce organic matter and suspended solids. The plant discharges 2.34 units of treated wastewater daily. In Brazil, wastewater treatment plants are regulated by the National Environment Council (CONAMA) and state environmental agencies, which set discharge standards to protect water quality. The plant's discharge likely enters a local watercourse that flows into the Atlantic Ocean, given its proximity to the coast. The coastal waters of Bahia support diverse marine ecosystems, including coral reefs and mangroves, which are sensitive to nutrient pollution. Proper treatment helps minimize environmental impact on these habitats.

The plant is located near the coast of Bahia, within the drainage basin that flows into the Atlantic Ocean. The receiving waters are part of the Todos os Santos Bay region, an ecologically important area that supports mangroves, seagrass beds, and diverse marine life. Discharges from the plant, though small, contribute to the overall nutrient load in the coastal zone, where secondary treatment helps reduce organic pollution.
