The desert is survivable in the summer thanks in large part to swimming pools. A lot of swimming pools. The mere act of dunking the body in cooler than body temperature water drops the core temperature and ensures a better night's sleep. (And if there are children, the splashing and swimming use a lot of energy also ensuring sleep.)
Hubby, Blondie and I went to check the house and pool of a friend's home to discover the pool pump had been on (not unusual, it is cheaper to run at night than during the day); however, two to three inches of water were drained from the water level. This may not sound like much, but it is. A lot. It can take hours, and more than a few dollars, to recover the necessary water level.
After shutting down the pump, taking pictures, an e-mail was sent. I can't fathom the cost if this had gone on for a large number of days. Really, I can't tell how long it has/had gone on - at least two.

Water is a huge responsibility, especially in a place that gets so little of it each year.
