Overview
ETE SAPOLANDIA II is a secondary wastewater treatment plant in Manaus, Amazonas, Brazil, serving approximately 1,896 people. It discharges 227.34 cubic meters of treated effluent daily into the local watershed.
ETE SAPOLANDIA II is a municipal wastewater treatment facility located in Manaus, the capital of Amazonas state in Brazil's North Region. The plant serves a population of about 1,896 residents, reflecting its role in managing domestic wastewater for a smaller community within the greater Manaus metropolitan area. The plant provides secondary treatment, which is the standard biological process for reducing organic matter and suspended solids. In Brazil, wastewater treatment plants are regulated under national environmental standards (CONAMA resolutions) and state-level permits. For smaller agglomerations like this, secondary treatment is typical and meets the required effluent quality for discharge into freshwater bodies. The treated effluent from ETE SAPOLANDIA II is discharged into the local drainage system, which ultimately flows into the Amazon River basin. The Amazon River system is the largest river basin in the world, supporting immense biodiversity and critical ecosystem services. Proper treatment helps protect downstream water quality and aquatic habitats in this ecologically sensitive region.
Environmental context
The plant discharges into the Amazon River basin, the world's largest river system by volume, which drains into the Atlantic Ocean. This watershed supports an extraordinary diversity of aquatic life, including thousands of fish species, and is vital for the ecological health of the Amazon rainforest. Effective wastewater treatment is crucial to prevent nutrient pollution and protect downstream ecosystems.
