What do they have water tanks on top for?
In order to feed water to the top of a tall building on demand would
require huge-to-massive pumps. Instead smaller, continuous flow
pumps move a small amount of water upwards to large tanks that then
gravity feed downwards. In particularly tall buildings intermediate
tanks and pumps are used, such that the load on a given set of
pumps (and the pressure that the plumbing must accommodate) are
tractable.
