Eli5 why do we run out of water?

Question

I know we need to conserve water and such but why? Doesn’t it eventually flow back into the ground or evaporated and rained back down regardless of how it’s consumed, so it’s a cycle? Do we lose a bit per cycle?

Another solution is to compost waste instead of mixing everuthing that has to go to a treatment plant, thereby making municiple water more efficient.
