Overview
ETE AH 03 is a secondary wastewater treatment plant in Manaus, Amazonas, Brazil, serving 542 people with a discharge volume of 64.95 cubic meters per day.
ETE AH 03 is a municipal wastewater treatment facility located in Manaus, the capital of Amazonas state in Brazil's North Region. The plant serves a small population of 542 residents, reflecting its role in a localized area of this large Amazonian city. The plant provides secondary treatment, which is the standard biological process required under Brazilian regulations (CONAMA resolutions) for urban wastewater. With a daily discharge volume of 64.95 cubic meters, the facility operates at a scale typical for a small community. Brazilian environmental law mandates that all wastewater treatment plants comply with discharge standards set by the National Environment Council (CONAMA), ensuring protection of water resources. The treated effluent is discharged into local waterways that ultimately drain into the Amazon River basin, the world's largest river system by discharge volume. This region hosts immense biodiversity, and proper wastewater treatment is critical to prevent nutrient pollution and protect aquatic ecosystems in the Amazon floodplain.
Environmental context
The plant's discharge enters the Amazon River basin, which flows through the world's largest tropical rainforest before reaching the Atlantic Ocean. The Amazon watershed supports an extraordinary diversity of fish, amphibians, and aquatic plants, and is a critical component of global carbon and water cycles. Even small treatment plants like ETE AH 03 play a role in maintaining water quality in this ecologically sensitive region.
