Usina Elevatória de Traição, Pumping station in Vila Olimpia, São Paulo, Brazil

Usina Elevatória de Traição stands on the Pinheiros River beside the Engenheiro Ary Torres Bridge, inaugurated in 1940 and run by EMAE. Its pumps lift water from the Pinheiros into the Billings Reservoir, feeding the Pedreira pumping station built in 1939 and, downstream, the Henry Borden plant at the foot of the Serra do Mar in Cubatão.

The station was built in 1940 as part of the Henry Borden hydroelectric system. It was designed to reverse water flow in the Tietê and Pinheiros rivers to support the water supply network for Santos.

The name comes from the Traição stream that ran near the site when the station was built. The plant is run by EMAE, the Metropolitan Company of Water and Energy, and its operation still decides whether the Pinheiros flows toward the Tietê or carries water to the Billings reservoir.

The station sits on the Pinheiros River beside the Engenheiro Ary Torres Bridge, in the Vila Olímpia area of São Paulo. It is a working facility run by EMAE, so there is no visitor entrance; the structure and the channel it controls are seen from the bridge and the riverside roads.

The station can pump water in both directions, an unusual feature that allows water from a reservoir to flow back into the river when needed. This flexibility was essential to the city's water management strategy.
