ETE Galileia 05 Wastewater Treatment Plant, Manaus, Amazonas

ETE Galileia 05 is a wastewater treatment plant located in Manaus, the capital of Amazonas state in northern Brazil. Serving a population of 758, this facility is part of the municipal sanitation infrastructure for the city's outlying areas. The plant operates in the heart of the Amazon rainforest, a region characterized by high rainfall and dense tropical ecosystems. The plant provides secondary treatment, which is the standard biological process for removing organic matter and suspended solids. Under Brazilian regulations (CONAMA resolutions), secondary treatment is typically required for urban wastewater to protect receiving water bodies. The plant's discharge volume is approximately 90.94 cubic meters per day, reflecting its small-scale operation. The treated effluent is discharged into local waterways that ultimately drain into the Amazon River system, the largest river basin in the world. This region supports immense biodiversity, including fish species, river dolphins, and flooded forest ecosystems. Proper treatment is critical to prevent nutrient loading and contamination that could harm aquatic life and downstream communities.

The plant discharges into the Amazon River basin, which flows through the Amazon rainforest and empties into the Atlantic Ocean. This watershed is ecologically sensitive, supporting diverse aquatic life including migratory fish and river dolphins. The region's high rainfall and warm temperatures create a dynamic environment where nutrient pollution can rapidly affect water quality and ecosystem health.
