Single‑family yards account for largest share of Phoenix water use, city trainer says

Summary
A City of Phoenix volunteer trainer told Water Wrangler volunteers that single‑family residences use about 51% of the water Phoenix supplies and outdoor residential use alone exceeds 30%, representing a major opportunity for conservation.
A volunteer coordinator with the City of Phoenix Water Department told trainees that single‑family homes account for roughly 51% of the water the utility supplies, and that outdoor residential watering alone is over 30% of delivered water.
That distribution means "about a third of the water that the water services department delivers in a year is going to water in your yard," the volunteer coordinator said, underscoring the agency's message that household landscaping choices represent a large potential for savings.
The distinction matters because, the coordinator said, residential outdoor use is greater than the entire commercial, industrial and institutional sector combined by more than 10 percentage points. "So every business, every industry, every restaurant, water park, and golf course combined uses less water than all single family homes," the coordinator added.
The training framed the statistics as a basis for outreach and conservation: Phoenix Water presents residential outdoor water use as the most promising target for reducing overall demand, and the volunteer program is intended to help residents adopt more efficient landscape irrigation and other measures.
The remarks were part of Lesson 4 of Phoenix Water Wrangler volunteer training, delivered by an unnamed volunteer coordinator from Phoenix Water. The session also noted climate variability in the Sonoran Desert — "we have a pretty big range on what to expect for precipitation" — and average local conditions (about 6 inches of rain annually and more than 300 sunny days per year) as context for why outdoor water use is both large and variable.
For volunteers and residents, the takeaway in the training was practical: individual choices about outdoor irrigation materially affect citywide water demand and constitute a major conservation opportunity going forward.
