ETE Serra do Navio | Secondary Wastewater Treatment Plant in Serra do Navio, Amapá, Brazil

ETE Serra do Navio is a municipal wastewater treatment plant located in the Pedra Preta area of Serra do Navio, in the state of Amapá, Brazil. The plant serves a population of 1,677 residents, providing secondary-level treatment to manage domestic wastewater in this small Amazonian community. The facility operates under Brazil's national environmental regulations, which require adequate treatment for wastewater discharges to protect water resources. With a discharge volume of 188.35 cubic meters, the plant's secondary treatment process reduces organic pollutants and suspended solids before effluent release. The treated effluent is discharged into local water bodies that drain into the Amazon River basin, ultimately reaching the Atlantic Ocean. This plant plays a key role in preserving water quality in the region's sensitive rainforest ecosystem, supporting aquatic life and downstream communities.

The plant discharges into local streams that are part of the Amazon River basin, one of the world's most biodiverse freshwater systems. The surrounding watershed supports dense rainforest and diverse aquatic species, including fish and invertebrates. Proper wastewater treatment is critical to prevent nutrient pollution and protect the ecological integrity of this globally important river system, which flows into the Atlantic Ocean.
