ETE VIVENDAS DO RIO - Secondary Wastewater Treatment Plant in Salvador, Bahia

ETE VIVENDAS DO RIO is a wastewater treatment plant located in the Patamares neighborhood of Salvador, the capital of Bahia state in northeastern Brazil. The plant serves a small population of 639 residents and operates at the secondary treatment level, which is the minimum standard required under Brazilian regulations for most urban wastewater. Secondary treatment at this plant involves biological processes to reduce organic matter and suspended solids before discharge. Brazilian environmental law, through CONAMA resolutions and state-level permits, sets effluent standards for such facilities to protect water quality. The plant is situated within 10 km of the Atlantic coast, and its treated effluent likely drains into coastal waters via local streams or the Bay of All Saints. This coastal discharge requires careful management to protect marine ecosystems, including coral reefs and mangroves that are ecologically sensitive and support diverse aquatic life.

The plant discharges into the Atlantic Ocean near Salvador, within the Bay of All Saints, a large tropical estuary. This coastal area supports mangroves, seagrass beds, and coral reefs that provide critical habitat for fish and crustaceans. Proper treatment is essential to prevent nutrient pollution and protect these sensitive marine ecosystems.
