Overview
ETE Redencao Rio Branco is a municipal wastewater treatment plant serving Rio Branco, Acre, Brazil. It treats wastewater for approximately 103,629 people in the Amazon region.
ETE Redencao Rio Branco is a wastewater treatment plant located in Rio Branco, the capital of Acre state in Brazil's northern Amazon region. The plant serves a population of approximately 103,629 people, making it a medium-to-large agglomeration under Brazilian regulatory frameworks. Brazil's wastewater treatment standards are governed by CONAMA resolutions and state-level environmental agencies. For plants of this scale, secondary treatment is typically required, with additional nutrient removal in sensitive areas. It operates under the national sanitation framework. The plant discharges into local water bodies that eventually drain into the Amazon River basin. The region's tropical climate and dense rainforest ecosystem make proper wastewater treatment critical for protecting aquatic biodiversity and preventing eutrophication in downstream rivers and floodplains.
Environmental context
The plant is located in the Amazon basin, where treated effluent likely flows into tributaries of the Purus River or the Acre River, both part of the larger Amazon River system. The surrounding rainforest supports diverse aquatic life, including fish species that migrate through the basin. Proper treatment is essential to prevent nutrient pollution and protect downstream ecosystems, including seasonally flooded forests and wetlands.
