Various large size purified water bottles can be found almost anywhere in Mexico - filled with good water. We buy new ones and stock up if we know we will be somewhere we might not be able to find good water. But it is rare that we cannot find bottled water. Many places we go now have good tap water so we ask around and if other folks are drinking then we drink too. Haven't gotten sick in a very long time. We do know people we RV over in the Yucatan who pay the water hauler trucks to come to fill up their fresh tanks with drinkable water but that is mostly because water over there tastes and smells bad.
