if there's lots of sun, why not distill the water you drink in
a greenhouse and filter the rest through a high-temp wetland
in the greenhouse that serves as the evaporator?
if it's really a desert, you may be able to use night ventilation
and indoor thermal mass instead of a swamp cooler, although you could
make a swamp cooler with a small indoor wetland and a small fan to
bring in some outdoor air, given a house with lots of insulation
