Will your location not have access to water??? We currently run a drive thru that is hard plumbed from a 25 gallon fresh water holding tank. We have 5 gallon water containers that we fill up at our local grocery store and then fill the 25 gallon tank from the 5 gallon tanks. When you run the faucet, etc. the water is then coming from the bottled water that we bring in. Kind of a pain in the butt but we didn't have any other options.
