ETE W TORRES Wastewater Treatment Plant, Parauapebas, Pará, Brazil

ETE W TORRES is a wastewater treatment facility located in Parauapebas, a city in the state of Pará, Brazil. The plant serves a small population of 1,723 residents, providing advanced treatment to ensure high-quality effluent. It is situated in the northern region of Brazil, within the Amazon biome, where water resource management is critical for preserving sensitive ecosystems. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other contaminants. This level of treatment is appropriate for protecting receiving waters in ecologically sensitive areas. Under Brazilian regulations, wastewater treatment plants are subject to federal standards such as CONAMA resolutions, which set discharge limits for various parameters. The treated effluent from ETE W TORRES is discharged into local water bodies that ultimately drain into the Amazon River basin. The Amazon region is home to diverse aquatic life and important migratory corridors. By providing advanced treatment, the plant helps reduce nutrient loading and protects downstream ecosystems, including floodplains and tributaries that support fish and other wildlife.

The plant discharges into local streams that flow into the Tocantins River basin, part of the larger Amazon River system. This watershed supports a rich diversity of aquatic species and is critical for maintaining water quality in the Amazon lowlands. The advanced treatment helps mitigate impacts on sensitive habitats, including floodplain forests and wetlands that provide breeding grounds for fish and migratory birds.
