Overview
ETE DeBORAH is a secondary treatment plant serving 3,250 people in Manaus, Amazonas, Brazil. It discharges 389.72 cubic meters of treated wastewater daily into the local watershed.
ETE DeBORAH is a wastewater treatment plant located in Manaus, the capital of Amazonas state in Brazil's North Region. Serving a population of 3,250, it is a small-scale facility that plays a role in managing domestic wastewater in this rapidly growing Amazonian city. The plant provides secondary treatment, which is the standard biological process for removing organic matter and suspended solids. Brazilian regulations under CONAMA Resolution 430/2011 require secondary treatment or equivalent for most urban wastewater discharges. Plants of this scale typically use activated sludge or lagoon systems. The treated effluent is discharged into the local water system, which ultimately drains into the Amazon River basin. The Amazon River system is the largest river network in the world, supporting immense biodiversity. Proper treatment is critical to protect downstream aquatic ecosystems and the communities that rely on these waters for fishing and drinking water.
Environmental context
The plant discharges into the Amazon River basin, the world's largest river system by volume. This watershed supports a vast array of aquatic life, including fish species that migrate through the basin. The Amazon River flows into the Atlantic Ocean, and its estuary is ecologically sensitive, with mangroves and floodplains that depend on clean water. Effective wastewater treatment helps prevent nutrient pollution and pathogen contamination in this globally important ecosystem.
