Reply to crescentCityRay: The pumpstation is a combination of 13 pump bays side by side and two sets of gates. Like another poster said, it is not on the Mississippi, it is on the Gulf intercostal water ways. It will be located just south of the convergence of the Harvey and Algiers canals. Each bay will pump 1500 gal/sec which combined will pump about 20,000 gal/sec combined. It could fill the Superdome in just over an hour. There will also be 13, 23,000 Gal tanks to feed these 13 pumps along with 13, 500 Gal day tanks. The USACE is wasting alot of money on this and other projects to save the idoits that live below sea level. if you are worried about flooding, ugh DONT LIVE BELOW SEA LEVEL! One thing to keep in mind is that all pumpstations now have safe houses where the crew can live to ensure the pumps stay on during the hurricane. They also have generators to power every thing. And to let you know 500m is not the cost of the pumpstation, it is a bit more.
