Overview
ETE RIVIERA LAURO DE FREITAS is a secondary treatment plant serving 4,352 people in Lauro de Freitas, Bahia, Brazil. It discharges 50.02 units of treated wastewater near the Atlantic coast.
ETE RIVIERA LAURO DE FREITAS is a wastewater treatment plant located in the Portão neighborhood of Lauro de Freitas, within the Metropolitan Region of Salvador, Bahia, Brazil. The plant serves a population of 4,352 residents, classifying it as a small-scale municipal facility in the northeastern region of the country. The plant provides secondary treatment, which is the standard biological treatment stage required under Brazilian regulations (CONAMA resolutions) for most urban wastewater. The reported discharge volume of 50.02 units suggests a modest operational scale consistent with the population served. The treated effluent is discharged into the local environment within 10 km of the Atlantic coast, ultimately reaching the Bay of All Saints (Baía de Todos os Santos), one of Brazil's largest and most ecologically significant coastal bays. This bay supports diverse marine life, including mangroves and coral reefs, and is an important fishing and tourism resource for the region.
Environmental context
The plant's discharge enters the coastal watershed of the Bay of All Saints, a large tropical estuary that receives drainage from multiple rivers and urban areas. The bay supports mangroves, seagrass beds, and coral reefs, providing critical habitat for fish, crustaceans, and migratory birds. As a coastal facility, the plant's nutrient and pathogen removal performance directly affects water quality in nearby beaches and shellfish areas.
