I know of one city in west Texas, actually it is on the South Plains, where such a hydrant is used for the city water supply. Everyone pulls up with their tank and fills up.

Some homes have running water but only if they are with-in a mile or so of the Courthouse. The rest were built before the city put in a water system so they have to use the hydrant.

And woe be unto anyone who is not a citizen of the town who uses the water. Everyone knows everyone so an outsider is easy to spot and the fines are enough to make a person consider buying their water at WalMart.
