Problem:

Take one of these:


And fill it in 5 minutes.

I am no engineer. :) But, when I first read about this, I thought of something involving an air tank at the top, and a refill point more toward the bottom. You would have to fill the reservoir under pressure (or else pressurize the air tanks after fill), but the extra air pressure from above would tend to force the water out faster.

Now, that could be an utterly useless idea, too.

I still like my 50 m tower idea containing exactly 200K litres and a trapdoor valve. Might be an issue with snapping the truck or popping the tires, and utterly impractical.

What about a hopper, 2 m square outlet, 10m square, 5m high.
