The Nabateans, as a whole, had mastered means of diverting, collecting and storing the water from the occasional gully-washer rain events to which those deserts are prone. Not that they were the only ones in that region to have done so - the Tanakh is replete with references, similes and analogies to desert water courses, cisterns, catch basins and the like - but by Roman times the Nabateans seem to have pretty well perfected the technology, enabling use of overland caravan shortcuts in support of their far flung trading empire.
I'll try to locate some references, within my vast horde of stuff, or provide some links.
