Well, for one, if you get low pressure in one set of water pipes the entire water grid doesn't attempt to collapse because it goes out of sync.
The grid is a gigantic clock that at least in the US is running at 60 ticks per second. This is pretty easy to manage if you have some massive power source on it like gigantic turbines at a nuclear power plant. All your small clocks aren't going to push that around so much.
The problems come in when all you have is small clocks, who sets the phase of the grid?
