Overview
ETE Praia de Buraquinho is a secondary treatment plant in Lauro de Freitas, Bahia, Brazil, serving 1,380 people and discharging 15.86 million liters daily near the coast.
ETE Praia de Buraquinho is a wastewater treatment plant located in Lauro de Freitas, within the metropolitan region of Salvador, Bahia, Brazil. It serves a population of 1,380 and operates with secondary treatment, discharging an average volume of 15.86 million liters per day. The plant provides secondary treatment, which is the standard biological process for removing organic matter and suspended solids. In Brazil, wastewater treatment is regulated by CONAMA resolutions and state environmental agencies, with secondary treatment being the minimum requirement for most urban areas. The plant's coastal location places it under additional scrutiny for nutrient removal to protect marine ecosystems. The treated effluent is discharged into the Atlantic Ocean via local drainage, as the plant lies within 10 km of the coast. This coastal discharge affects the water quality of nearby beaches and the broader Todos os Santos Bay, an ecologically important area supporting mangroves, coral reefs, and diverse marine life. Proper treatment is essential to prevent eutrophication and protect public health in this densely populated region.
Environmental context
The plant discharges into the Atlantic Ocean near Lauro de Freitas, part of the Todos os Santos Bay watershed. This bay is a large tropical estuary with extensive mangrove forests and seagrass beds that serve as nursery habitats for fish and crustaceans. Coastal discharge of treated wastewater must meet strict nutrient limits to avoid algal blooms and oxygen depletion, which can harm the bay's biodiversity and the local fishing economy.
