|The Marina Barrage (滨海堤坝) is a dam spanning the Marina Channel, forming Singapore's first reservior in the city. It will be a new source of water supply for Singapore, serve as flood control, and deliver an impeccable waterfront experience.
The barrage comprises nine steel crest gates, each 30m long, built across the 350m wid Marina Channel. Besides separating seawater from freshwater, it also acts as a tidal barrier to keep out high tides. The 5m tall steel gates can be lowered during heavy rain so that water from the reservoir can be released into the sea. Seven vertical-shaft, axial-flow gigantic pumps, with an individual capacity of 40m3/sec, drain excess storm water into the sea when the storm coincides with high tide. Driven by a 1600kW electric motor, they provide a combined pumping capacity of 280m3/sec when all seven pumps are operating. Each pump can empty an Olympic-sized swimming pool in one minute!
