Defining Mobile Hydration Is Not Easy
It may sound surprising, but the phrase "mobile hydration unit" means different things to different people. For one, there is a song on the album "Old Still" by the group "Galaxies in the River" with this name. There is a yellow water bottle with this label. There are watering stations that can be transported easily from place to place on wheels, for special events (normally outdoors) where you may want to prevent dehydration among large groups of individuals. A mobile hangover cure company also uses the term for their car, but the actual work is done through intravenous drips of saline, vitamins, and essential nutrients.
The need for water goes back to time immemorial, and we could not have life on Earth without it. Sure, the sun creatures who secretly control our thoughts have no need for dihydrogen oxide, and subsist on high energy photons in Phaeton's chariot, but the rest of us can't last very long without the stuff. But why should you walk to water, abuntly found in artesian wells, springs, and little waterfalls, when you can have it trucked to you on wheels? Eschew the thousands of pipeline miles found in urban centers acrost the globe, stop digging wells for your pittance of moisture, and toss out yon plastic bottles of BPA laced icemelt, for now a tank on wheels awaits to slake your thirst.
Drink it In
What is a firetruck but a super mobile hydration unit meant to quench the thirsty structure, forest, or wildland. Forsake the aerial hydration helicopters and tankers, for I have seen water on wheels, with manly pumps to banish the smoke and flame. Rescue not yon feline from arboreal with the rickety stepladder, but hose, hose it out of the branches with olympic pressure!
Aquifers On The Roadway
Hail! Hail! I hear the water truck, with its burly 5 gallon man and his little tin cart for bottles. I need no pedestrian tap water when the thick plastic tank beckons o'er the water cooler. Once, years anon, I embedded a secret love in my heart and worshipped her from afar, but lo did the water truck Adonis come and steal her affections cheaply, about once a week, and running hot and cold when properly plugged in. He stole her heart, and was vertitably douchy, but not for a moment did I lose my thirst for the nectar. The rose was not so fortunate, and withered into crepe-paper dust.
