ETE VILA RITA Wastewater Treatment Plant, Salvador, Bahia

ETE VILA RITA is a wastewater treatment plant located in the Trobogy neighborhood of Salvador, Bahia, Brazil. It serves a small population of 283 people, reflecting its role as a local facility within the metropolitan region of Salvador. The plant is situated in the Northeast Region of Brazil, a coastal area with significant urban and environmental pressures. The plant provides secondary treatment, which is the standard level required under Brazilian regulations (CONAMA resolutions) for most inland and coastal discharges. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant's discharge volume of 30.54 units suggests it operates at a scale appropriate for its small service population. The treated effluent is discharged into the local watershed, which ultimately drains into the Atlantic Ocean via the Bay of All Saints (Baía de Todos os Santos). This bay is a large, ecologically important estuary that supports diverse marine life, including mangroves and fish species. The plant's proximity to the coast (within 10 km) means its discharge can directly affect coastal water quality and marine ecosystems.

The plant discharges into the watershed of the Bay of All Saints (Baía de Todos os Santos), a large tropical estuary in Bahia that opens to the Atlantic Ocean. This bay is ecologically sensitive, supporting mangroves, seagrass beds, and diverse aquatic life, including species of commercial and conservation importance. The plant's coastal location means treated effluent can influence nearshore water quality and marine habitats.
