"Irrigated agriculture is the largest user of water in Arizona, consuming about 74 percent of the available water supply." https://new.azwater.gov/conservation/agriculture
"In Arizona, approximately 15 percent of the water supply is for commercial, industrial and institutional uses." https://new.azwater.gov/conservation/commercial-industrial
So it's on us to do everything we can to optimize the last 10% of all the available water.
To be clear I think we all should do our part, but there are so many misleading news stories that fail to even acknowledge the reality of our water distribution.
