ETE IBEROSTAR Wastewater Treatment Plant, Mata de São João, Bahia

ETE IBEROSTAR is a wastewater treatment plant located in Açu da Torre, Mata de São João, within the Metropolitan Region of Salvador, Bahia, Brazil. The plant serves a small population of 1,636 people, reflecting its role in a coastal community in the Northeast Region of Brazil. The plant provides secondary treatment, which is the standard biological treatment required under Brazilian regulations for municipal wastewater. The plant operates within Brazil's national environmental framework, which mandates treatment to protect water quality. The plant discharges a daily volume of 49.46 units of treated wastewater. The treated effluent from ETE IBEROSTAR is discharged into a receiving water body that ultimately flows to the Atlantic Ocean, given its proximity to the coast. The plant's location within 10 km of the coast means its discharge can influence coastal water quality and marine ecosystems, including nearby beaches and mangroves that support diverse aquatic life.

The plant discharges into a coastal watershed that drains to the Atlantic Ocean near the Costa dos Coqueiros region. This area features mangroves and estuaries that serve as critical nursery habitats for fish and crustaceans. The proximity to the coast means treated effluent can affect nearshore water quality and marine biodiversity, particularly in sensitive coastal ecosystems.
