In areas without much water,
wasting water is a real concern and therefore it probably shouldn't be
used for lawns.

My water company* paid $2.00 a sq ft, for me to remove the lawn turf.
11 tons of rock, capped sprinkler lines, weed cloth, photos, rules,
inspections, etc. They sent me a check.

Plants and trees are on drip lines, timed schedules. We have a yearly
calendar, and change from once or twice a week, up to every day in the
summer months.

New construction homes cannot have turf lawns anymore. The option is
artificial grass.

I never looked back after taking *out most of my lawn.

Nevada is NOT Northern Texas. Your solution make perfect sense for
Nevada but not so for everywhere.
