This pump's 5,000-horsepower diesel engine spins a four-blade propeller 150 times a minute. The result is the movement of 15 Olympic-size-swimming-pools worth of water every minute (that's 150,000 gallons per second). A $500 million investment, the pump is protected by 32-foot-tall, 225-foot-wide steel gates, which reach the river's bottom and are able to withstand a 16-foot storm surge. As if that wasn't enough, a 12-foot-thick concrete slab holds the gates, and that slab has its own support—518 steel pilings, each able to withstand more than 435,000 pounds.
