Me: Yep! We've built them for mines.
C: Good. We have Euclids with 200 tonne* tanks we use to spray the roads.
Me: That won't be a problem, we can build to suit.
C: But there's a power problem. The fill stations will have to use gravity to move the water.
Me: That's still not a problem. We've built gravity-fed systems before.
C: And the tankers have to fill in less than 5 minutes.
Me: (grabs calculator. 200,000/300=667 litres/second)
Over half a tonne of water per second. Fed by gravity. Time to talk to a hydraulic engineer.
