Overview
ETE VILA REAL II is a secondary wastewater treatment plant in Manaus, Amazonas, Brazil, serving approximately 542 people. It discharges treated effluent into the local watershed within the Amazon River basin.
ETE VILA REAL II is a wastewater treatment facility located in Manaus, the capital of Amazonas state in northern Brazil. Serving a population of about 542 people, it is a small-scale plant situated in the heart of the Amazon rainforest, a region characterized by high rainfall and dense tropical ecosystems. The plant provides secondary treatment, which is the standard biological process for removing organic matter and suspended solids. Under Brazil's national environmental regulations (CONAMA resolutions and the National Water Resources Policy), small plants like this are typically required to meet effluent standards for BOD and TSS before discharge. The plant's discharge volume is approximately 64.95 cubic meters per day, reflecting its small service population. The treated effluent is released into local watercourses that ultimately drain into the Amazon River system, the largest river basin in the world by discharge volume. This basin supports immense biodiversity and is critical for global climate regulation. The plant's location in a sensitive tropical watershed underscores the importance of proper treatment to protect downstream aquatic life and water quality.
Environmental context
The plant discharges into the Amazon River basin, which flows through the Amazon rainforest into the Atlantic Ocean. This watershed is one of the most biodiverse on Earth, supporting countless fish species, aquatic mammals, and riparian habitats. Even small treatment plants like ETE VILA REAL II play a role in maintaining water quality in this ecologically sensitive region, where nutrient loading and pathogen contamination can impact downstream communities and ecosystems.
