ETE CAMAMU Wastewater Treatment Plant, Maraú, Bahia, Brazil

ETE CAMAMU is a wastewater treatment plant located in the Piabanha district of Maraú, Bahia, Brazil. The facility serves the local population of about 8,688 residents, providing secondary treatment for municipal wastewater. As a plant in the northeastern region of Brazil, it operates within the country's national environmental framework. The plant employs secondary treatment processes, which involve biological degradation of organic matter. The plant's discharge volume of 614.44 m³/day indicates its operational scale. In Brazil, wastewater treatment plants are regulated by federal and state environmental agencies, with standards set by CONAMA resolutions. The treated effluent is discharged into local water bodies that ultimately drain into the Atlantic Ocean. The region's watershed supports diverse aquatic ecosystems, including mangroves and coastal habitats. The plant plays a key role in protecting these environments by reducing pollutant loads before discharge.

The plant discharges into local waterways that flow toward the Atlantic Ocean, passing through coastal ecosystems such as mangroves and estuaries. These habitats are ecologically sensitive, supporting fish, crustaceans, and migratory birds. Proper treatment is essential to prevent nutrient enrichment and maintain water quality in the downstream marine environment.
