I see 8 "loads" of water, maybe 1-2 gallons per load in 13 seconds. Thats about 37 loads per minute, 2220 per hour. So they are pumping between 2220 and 4440 gallons per hour. Thats a lot of water!! I realize they cannot do that for an hour, but it is still an impressive number.

On second thought, they very well might be able to do that for an hour!!
