Overview
ETE Sao Cristovao Salvador is a secondary treatment plant serving 211 people in Salvador, Bahia, Brazil. It discharges 22.84 units of treated wastewater near the Atlantic coast.
ETE Sao Cristovao Salvador is a wastewater treatment plant located in the Sao Cristovao neighborhood of Salvador, the capital of Bahia state in northeastern Brazil. The plant serves a small population of 211 people and operates at a secondary treatment level, which is typical for smaller agglomerations in the region. As a secondary treatment facility, the plant provides biological treatment to reduce organic matter and suspended solids. The plant's scale aligns with Brazil's regulatory framework for wastewater treatment, which mandates appropriate treatment for all urban discharges. The plant is situated in a densely populated urban area within the metropolitan region of Salvador. The plant's treated effluent is discharged into the local drainage system, which ultimately flows into the Atlantic Ocean. Salvador's coastal location means that the plant's discharge contributes to the broader environmental context of the Bay of All Saints (Baia de Todos os Santos), a large tropical bay that supports diverse marine life and is an important ecological and economic resource for the region.
Environmental context
The plant discharges into the local watershed that drains into the Bay of All Saints (Baia de Todos os Santos), a large tropical bay on the Atlantic coast of Brazil. This bay is an ecologically productive estuary supporting mangroves, seagrass beds, and diverse fish and crustacean species. The plant's proximity to the coast (within 10 km) means its secondary-treated effluent enters a sensitive marine environment where nutrient loading can affect water quality and aquatic ecosystems.
