Not sure which specific sources of random data-points you've picked from around the internet, but generally to arrive at the figure of x litres of water per y litres of milk, a full life-cycle analysis is done which would typically account for feed production and feed transport. So there's going to be a lot of overlap in your figures.
Secondly, the energy requirements for getting fully treated drinkable water to residential taps is going to be significantly different than that required to supply agricultural water for irrigation, etc.—at least a portion of that should be untreated/reclaimed waste water.
