What about the ocean?
Desalinized water is potable and easy to refine. That being said, it's extremely lazy to say we are running out of water. There's also a nigh endless supply of underground wells that have yet to be tapped.... Soooo, ya. Not quite out of water yet.

The city of Phoenix is facing an interesting problem from over-tapping the aquifers under the city there....the entire Valley of the Sun is sinking as the aquifers are drained.

Whatever water began here on earth, is most likely here to stay. Nice try, but it isn't going anywhere.
Most of the groundwater sprayed on thirsty croplands across America makes its way into streams and rivers. Even though much of the water seeps into the soil first, the vast majority never makes its way back into the aquifer. Instead, it heads toward the sea, where it eventually contributes a surprising share of global sea level rise, reports Leonard Konikow, a hydrogeologist with the U.S. Geological Survey.

In the state of Texas my Local lake has dropped 20.6 FT in less then a year. In San Antonio areas like bayer county they ran out of water and had to start using recycled sewage water. Here where I live San Antonio has been trying to take water from our lake for about a year know. They lost here in mhy county because america has a treaty agreement with Mexico to supply X amount of water therefore we cannot giveup water to a mega city. SO what the builders did was go along the 150 mile stretch between our lake and San Antonio and payed the Ranchers and Hunting ranches to put large Water pumps into the underground Major river systen that supplies our lake and as a result we lost 20.6 FT of level in less then a year and had to cut the flow to mexico 6 days ago. Our county has put junction type order on the ranchers and hunting ranches to temorarily stop the water leaving the river while the county takes them to supreme court to over rule any access off the 2 main rivers.
Yes america like many other nations are facing a slow but quicking water crises. ( My opinion, Over population= decrease in natural resources)

Wait, OP, we "need" oil?
We "need" H2O to survive. We can get by with dozens of new patents that are currently not being put into public use that make oil obsolete....when that day comes?

In the navy, we use desalination on board all our ships. Fresh water is essential for a boiler to work (you can't use salt water).
The main problem with desalination is that it takes energy to do that, and you'll have to then pipe that water inland from the coastal areas.
None of these are huge problems that can not be over come. I'm sure desalination plants can run on green energy, however the piping might be a problem, especially if you are having to make a pipeline though areas that are protected (environmentalists). While the water itself is of course not dangerous to the environment, they'll be concerned with the pipeline itself. Disrupting or destroying habitats to build it.
At the same time however, I'm not seeing any real headlines about water shortages, except places like Texas last year with the severe rain shortage they had (and during the winter). I can see where places like that, who are in drought conditions should be concerned.
I do have to agree though: if major population centers in the desert are having the most problem, then the answer is simple: don't build there! hehehehe.
I know, I know, a over simplified answer, but it runs along the same lines as so many people being shocked when they build in hurricane prone areas, and one comes along to wipe them out. Or building along major fault lines......or on the sides or near a volcano.......
