ETE AMARANTE RN is a wastewater treatment facility located in the Regomoleiro area of São Gonçalo do Amarante, within the metropolitan region of Natal, Rio Grande do Norte, Brazil. The plant serves a population of about 5,187 people, classifying it as a small-scale municipal treatment system in the northeastern region of the country. The plant provides secondary treatment, which is the standard level required under Brazilian regulations (CONAMA Resolution 430/2011) for most inland and coastal discharges. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant discharges an average of 823.27 cubic meters of treated wastewater per day. The treated effluent is discharged into the local watershed, which drains toward the Atlantic Ocean. The plant's proximity to the coast (within 10 km) means its discharge can influence coastal water quality. The region's tropical climate and seasonal rainfall patterns affect dilution and assimilation capacity of receiving waters. Proper treatment is essential to protect downstream ecosystems and recreational waters near Natal.
Environmental context
The plant discharges into the coastal drainage system of Rio Grande do Norte, ultimately reaching the Atlantic Ocean near the Natal coast. The receiving waters support diverse aquatic life and are important for local fisheries and tourism. The nearby Potengi River estuary and coastal mangroves provide critical nursery habitats for marine species. Effective wastewater treatment helps prevent nutrient enrichment and pathogen contamination in these sensitive coastal environments.
