There ARE lots of solutions here. Honestly, either we CAN do something or we can whine. There are really no other options. I thot Americans were resourceful in an pinch? What a bunch of ............................. they are(oh nevermind).
You could just as well equip a bunch of people with eyedroppers. If you build a cofferdam around a small area, a firetruck pump might be useful for evacuating it. This could be a good approach for getting at presently-submerged pumps to repare them. But a week of pumping by a firetruck probably wouldn't equal an hour's worth of pumping by one of the monster pumps.
Way cool!
And then the water would run right back into the city and you
would have continuous employment. What do your temp pumps weigh?
Can they be broken down and transported overland?
Is the road clear?
Do these pumps run on diesel?
Is diesel available?
Where are the pump hands going to stay?
Not really jumping on your case, but I've often wondered at people, such as yourself and many others on this same thread, posting this stuff off the top of their heads without giving it a second's thought. The existing pump facilities, which unfortunately aren't working, have a combined 22 million gallon/minute capacity. I've seen estimates that even if they were all working 24 hours/day, it would take 15 days to pump New Orleans dry. By comparison, a top of the line fire engine has about a 1000 gal./min. capacity, so all we have to do is find 22,000 fire engines and send them to New Orleans to get the job done in the same time.
