Overview
ETE Cajazeiras VIII TQ 2 is a secondary treatment plant in Salvador, Bahia, Brazil, serving about 4,600 people. It discharges treated wastewater near the coast, impacting the local marine environment.
ETE Cajazeiras VIII TQ 2 is a wastewater treatment plant located in the Cajazeiras neighborhood of Salvador, the capital of Bahia state in northeastern Brazil. The plant serves a population of approximately 4,621 people, making it 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's discharge volume is reported at 499.47 cubic meters per day. The treated effluent is released into the local watershed, which ultimately drains into the Atlantic Ocean. Given the plant's proximity to the coast (within 10 km), the discharge may affect coastal water quality and marine ecosystems. The region's tropical climate and urban setting necessitate careful management to protect downstream environments.
Environmental context
The plant discharges into the drainage network of Salvador, which flows into the Baía de Todos os Santos, a large tropical bay in northeastern Brazil. This bay supports diverse marine life, including mangroves, coral reefs, and fish populations. The bay is ecologically sensitive due to urban runoff and industrial activities in the Salvador metropolitan area. Proper treatment is essential to minimize nutrient loading and protect the bay's biodiversity.
