ETE ACARI is a wastewater treatment plant located in Acari, within the state of Rio Grande do Norte, Brazil. It serves a population of around 8,165 residents, placing it in the small agglomeration category. The plant is situated inland, away from coastal areas, and treats municipal wastewater for the local community. The plant provides secondary treatment, which is the standard level required under Brazilian regulations for communities of this size. Secondary treatment typically involves biological processes to remove organic matter and suspended solids. In Brazil, wastewater treatment plants are regulated by federal and state environmental agencies, with permits ensuring compliance with discharge standards. The treated effluent from ETE ACARI is discharged into local water bodies that eventually drain into the Piranhas-Açu river basin, which flows into the Atlantic Ocean. This region is part of the semi-arid Northeast of Brazil, where water resources are critical for agriculture and local ecosystems. The plant plays a key role in protecting downstream water quality and supporting the health of the riverine environment.
