ETE Eliza Miranda Wastewater Treatment Plant, Manaus, Amazonas, Brazil

ETE Eliza Miranda is a wastewater treatment facility located in Manaus, the capital of Amazonas state in northern Brazil. The plant serves a population of about 8,936 residents, contributing to the sanitation infrastructure of this major Amazonian city. As part of Brazil's growing urban wastewater network, the plant plays a role in managing domestic sewage from the surrounding area. Brazil's wastewater treatment sector is regulated under national standards such as CONAMA resolutions and the National Sanitation Plan (PLANSAB). For a plant of this scale, secondary treatment is typically expected to meet effluent quality standards. The facility operates within the context of Brazil's efforts to expand sanitation coverage, particularly in the Amazon region where infrastructure challenges are significant. The plant's treated effluent likely discharges into a local watercourse that flows into the Rio Negro, a major tributary of the Amazon River. The Amazon basin is the world's largest river system, supporting immense biodiversity and critical ecological functions. Proper treatment is essential to protect water quality in this globally significant watershed.

The plant is situated in Manaus, within the Amazon River basin. Treated effluent likely enters a local stream that drains into the Rio Negro, which joins the Amazon River near Manaus. The Amazon watershed hosts unparalleled biodiversity, including thousands of fish species and extensive floodplain forests. Effective wastewater treatment is crucial to prevent nutrient loading and contamination that could harm aquatic ecosystems and downstream communities.
