ETE VINA DELMAR Wastewater Treatment Plant, Salvador, Bahia

ETE VINA DELMAR is a municipal wastewater treatment plant located in the Vila Nova Brasília neighborhood of Salvador, Bahia, Brazil. The plant serves a small population of 383 residents and operates with secondary treatment, which is typical for smaller communities in the region. The plant discharges approximately 41.42 cubic meters of treated wastewater. As a secondary treatment facility, it provides biological treatment to reduce organic matter and suspended solids, meeting basic environmental standards for effluent quality before discharge. Located within 10 km of the Atlantic coast, the plant's discharge ultimately reaches the ocean, likely via local drainage channels or the Bay of All Saints. The coastal environment is ecologically sensitive, supporting diverse marine life and important fisheries. Proper treatment is essential to protect water quality and coastal ecosystems.

The plant is situated in Salvador, a coastal city on the Bay of All Saints, which opens to the Atlantic Ocean. The bay is a large estuarine system that supports mangrove forests, seagrass beds, and diverse aquatic species. Treated effluent from the plant enters this sensitive coastal environment, where nutrient loading and pathogens can impact water quality and marine life. Effective secondary treatment helps mitigate these risks.
