Water has always been an issue there. When I lived in AZ, developers were building entire neighborhoods in the desert with no access to water. Urban sprawl was outpacing infrastructure. The developers promised to lay water lines while residents had to depend on unreliable water truck deliveries for all their water. It was still going on at the time I went to Israel. Builders/Developers were being sued. Do not know how it ended, but I doubt the developers ever laid permanent water lines to these satellite communities. Maybe, I don't know.
Funny story is, they were building these homes on undeveloped sort of 'raw' land in the desert. It was not uncommon for the home owners to discover that their home was built on a migratory breeding site for some snake or scorpion. Over time they would discover hundreds or even thousands of scorpions and snakes (imagine the horror) returning to the place they had massed for one reason or another for thousands of years. And they refused to leave. For them, it was an instinctual drive.
