But bear with me. Put a unit or two like these self powered pumps on bridge pontoons, barges, etc. Throw up a coffer dam around the pump station, (after you float the barge in, or park the barge next to the dam).
Use these to pump out the pump stations to get them dry and repair the big pumps.
Re route electrical power as needed, the strip mining industry runs huge cables out to draglines from power plants, along the ground...
Then pump the place out. Wish for more wishes.
How many of those pumps are actually available?
