This pump's 5000-horsepower diesel engine spins a four-blade propeller 150 times a minute. The result is the movement of 15 Olympic-sized-swimming-pools worth of water every minute (i.e. 567,000 litres every second). A $US500 million investment, the pump is protected by 9.75m tall, 70m wide steel gates, which reach the river's bottom and are able to withstand a 4.8m storm surge. As if that wasn't enough, a 3.6m thick concrete slab holds the gates, and that slab has its own support - 518 steel pilings, each able to withstand more than 197,000kg.
