Overview
ETE SETE DE ABRIL is a secondary treatment plant in Salvador, Bahia, Brazil, serving about 900 people. It discharges treated wastewater near the coast, contributing to local water quality management.
ETE SETE DE ABRIL is a wastewater treatment plant located in the Jardim dos Girassóis neighborhood of Salvador, Bahia, Brazil. It serves a small population of approximately 900 residents as part of the city's municipal sanitation infrastructure. The plant is situated in the Região Metropolitana de Salvador, a densely populated coastal region. The plant provides secondary treatment, which is the standard biological treatment level required for urban wastewater under Brazilian regulations (CONAMA resolutions). Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. For a plant of this small scale, secondary treatment is appropriate and aligns with national standards for protecting water quality. Located within 10 km of the Atlantic coast, the plant's treated effluent likely discharges into local water bodies that drain into the Baía de Todos os Santos, one of Brazil's largest bays. This bay supports diverse marine life and is an important ecological and economic resource for the region. The plant's operation helps reduce pollution loads entering this sensitive coastal ecosystem.
Environmental context
The plant is situated in the coastal watershed of Salvador, with treated effluent likely flowing into small streams or drainage channels that eventually reach the Baía de Todos os Santos. This bay is a large, semi-enclosed estuary that supports mangroves, seagrass beds, and coral reefs, providing critical habitat for fish and crustaceans. The bay also receives urban runoff and industrial discharges, making the plant's secondary treatment important for mitigating nutrient and organic pollution. Downstream, the bay opens to the Atlantic Ocean, where coastal currents disperse treated water.
