ETE Galileia 09 Wastewater Treatment Plant, Manaus, Amazonas

ETE Galileia 09 is a wastewater treatment plant located in Manaus, the capital of Amazonas state in Brazil's Northern region. It serves a small population of 758 people, reflecting its role in a localized area of this large Amazonian city. The plant provides secondary treatment, which is a standard biological process that removes organic matter and suspended solids. For a facility of this scale, secondary treatment meets typical regulatory requirements under Brazilian environmental law, which mandates appropriate treatment for small agglomerations to protect water quality. The treated effluent is discharged into the local watershed, which ultimately drains into the Amazon River system. This region is ecologically sensitive due to its tropical rainforest biome and high biodiversity. The plant's operation helps mitigate pollution impacts on downstream aquatic ecosystems.

The plant discharges into a tributary of the Amazon River, the world's largest river by discharge volume. The downstream environment includes vast floodplains and rainforest ecosystems that support diverse aquatic life, including fish species and river dolphins. Protecting water quality in this region is critical for maintaining ecological balance and the livelihoods of local communities.
