ETE VILA NOVA I - Secondary Wastewater Treatment Plant in Manaus, Amazonas, Brazil

ETE VILA NOVA I is a wastewater treatment plant located in Manaus, the capital of Amazonas state in northern Brazil. Serving a small population of 839 residents, the plant plays a role in managing domestic wastewater within the urban fabric of this major Amazonian city. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. For small agglomerations in Brazil, secondary treatment is typical under national regulations, which align with general environmental standards for inland facilities. Situated in the heart of the Amazon basin, the plant's discharge ultimately contributes to the vast Amazon River system, which drains into the Atlantic Ocean. The surrounding ecosystem is one of the most biodiverse on Earth, and proper wastewater treatment is critical to protecting water quality in this sensitive tropical environment.

The plant is located in Manaus, within the Amazon River basin, the world's largest river system by discharge volume. Treated effluent from the plant eventually flows into the Negro River and then the Amazon River, which empties into the Atlantic Ocean. The region supports immense biodiversity, including numerous fish species and aquatic habitats that depend on clean water. Effective secondary treatment helps reduce nutrient and organic pollution, safeguarding downstream ecosystems in this globally significant watershed.
