ETE Santo Antônio is a municipal wastewater treatment plant located in Santo Antônio, within the state of Rio Grande do Norte in northeastern Brazil. The plant serves a local population of 4,565 residents, providing secondary-level treatment to manage domestic wastewater from the community. As a secondary treatment facility, ETE Santo Antônio employs biological processes to reduce organic matter and suspended solids, meeting the standards expected for small agglomerations under Brazilian environmental regulations. The plant discharges an average of 304.57 cubic meters of treated wastewater per day, reflecting its capacity to handle the community's wastewater load. The treated effluent from ETE Santo Antônio is discharged into local water bodies that eventually drain into the Atlantic Ocean via the coastal river systems of Rio Grande do Norte. The region's semi-arid climate and proximity to the coast make proper wastewater treatment essential for protecting downstream aquatic ecosystems and maintaining water quality in the broader drainage basin.

The plant discharges into local waterways that flow toward the Atlantic coast of Rio Grande do Norte, part of the Northeast Brazil drainage region. The receiving waters support diverse aquatic life and are important for local fisheries and recreation. Proper treatment helps prevent nutrient pollution and pathogen contamination in this ecologically sensitive coastal zone.
