ETE VIVENDAS DO ATLANTICO - Secondary Wastewater Treatment in Lauro de Freitas, Bahia

ETE VIVENDAS DO ATLANTICO is a municipal wastewater treatment plant located in the Vilas do Atlântico neighborhood of Lauro de Freitas, Bahia, Brazil. The plant serves a small population of approximately 1,500 residents within the Salvador metropolitan region, a coastal urban area in northeastern Brazil. The plant provides secondary treatment, which is the standard biological treatment stage that removes organic matter and suspended solids. As a small-scale facility in Brazil, it operates under the national environmental regulations overseen by the state environmental agency (INEMA in Bahia). Brazilian law requires adequate treatment for all urban wastewater, with secondary treatment being typical for communities of this size. The treated effluent is discharged into the local drainage system, which ultimately flows into the Atlantic Ocean near the coast of Lauro de Freitas. This coastal area supports mangrove ecosystems and marine biodiversity, making proper treatment essential to protect water quality and aquatic life in the region.

The plant discharges into the coastal watershed of Lauro de Freitas, which drains into the Atlantic Ocean via small rivers and estuaries. This region is part of the Todos os Santos Bay basin, an ecologically important area that supports mangroves, seagrass beds, and diverse marine species. The proximity to the coast means that treated effluent can influence nearshore water quality and coastal ecosystems, including coral reefs and fish habitats.
