I live in the desert Southwest and it was costing and arm and a leg to water my plants even though we have no lawn and plant desert adapted versions of plants. Trying to water sparingly just killed plants and made the survivors look droopy.
Finally, I bit the bullet and put in a drip system, which in the summer we run at night to reduce evaporation. Our water use was cut by 75% and the plants have never looked better.
To keep the drip working in this hard water area, every few weeks I pull all the drip tips and soak in vinegar, or CLR if they are really bad. Some of the desert adapted plants are versions of plants grown elsewhere, such as desert gold peaches, and some types of roses which bloom almost all year here with very little care and not much water. So we are able to have a nice, pretty yard that isn't all cactus, eat fresh fruit, and not spend a fortune.

Many vegetables such as tomatoes, squash, and peppers grow well in the desert heat. You will be able to grow more types of veggies by planting earlier in the year to avoid the summer heat.
