Meet Arizona's water one-percenters

Apr 5, 2021

Every two weeks, Dawn Upton floods her lawn. She treks into her back yard, twists open two valves big as dinner plates, and within minutes is ankle-deep in water.

“You have to have irrigation boots, girl,” she says during a video tour of her property in Mesa, a suburb of Phoenix, Arizona. She flips her camera to reveal green grass, then tilts her phone skyward at four towering palm trees. As she walks, she pans across pecan, pomegranate, and citrus trees – lemon, orange, a grapefruit sapling. A tortoise, between 80 and 100lb, lumbers toward her, chewing. “There’s Simba,” Upton says. “Hey buddy! What is that, Simba? You can’t eat it.” She pats him affectionately on the head.

This lush half-acre is Upton and her husband’s oasis, fed by flood irrigation in the heart of the Sonoran desert.

Upton is among a handful of homeowners – by one accounting, just 1% – of metro Phoenix’s 4.4 million people to receive flood irrigation. The Salt River Project, the area’s largest supplier of such water, delivered almost 60,000 acre-feet of water to that small number of residents in 2019, or 7.5% of the water it delivered that year to all customers combined.

In that same year, the Salt River Project sent 36,003 acre-feet to Phoenix-area schools, parks, golf courses and churches (and 63,500 acre-feet to farmers – another story entirely) to irrigate trees and turf.

To provide scale for that type of usage: one acre-foot of water can sustain three Phoenix-area families for a year. The entire city of Chandler, Arizona, population 261,000, uses 60,000 acre-feet of water annually.
