ETE Ozias Monteiro - Secondary Wastewater Treatment Plant in Manaus, Amazonas, Brazil

ETE Ozias Monteiro is a municipal wastewater treatment plant located in Manaus, the capital of Amazonas state in northern Brazil. The plant serves a small population of 271 residents, reflecting its role in a localized community within the broader urban area of Manaus. As a secondary treatment facility, it provides biological treatment to reduce organic pollutants before discharge. The plant operates under Brazil's national environmental regulations, which require wastewater treatment for urban agglomerations. For small communities like this, secondary treatment is the standard to protect water quality. The plant's discharge volume of 32.48 m³/day indicates a modest flow consistent with the population served. The treated effluent from ETE Ozias Monteiro is discharged into the Amazon River basin, one of the world's largest and most biodiverse freshwater systems. The receiving waters ultimately flow into the Amazon River, which empties into the Atlantic Ocean. This watershed supports a vast array of aquatic life and is critical for regional ecology and local communities.

The plant discharges into the Amazon River basin, which drains into the Amazon River and eventually the Atlantic Ocean. This watershed is ecologically sensitive, supporting diverse aquatic species including fish, reptiles, and mammals. The Amazon rainforest's hydrological cycle depends on clean water, making effective treatment essential to prevent nutrient loading and contamination that could harm downstream ecosystems.
