Ask an Arizona resident what they believe about golf course irrigation, and you’re likely to hear frustration. That frustration has little to do with the sport itself, or the tourists it draws — it’s about the water it takes to keep fairways green. Arizona’s cities are under increasing pressure to reduce their water use as this natural resource is scarce and reliant on a main source that faces growing pressure, the Colorado River.
While people make efforts to use water wisely, golf courses require millions of gallons per year to maintain their turf in an arid climate. Given that, it’s easy to see why golf irrigation draws public criticism. However, the situation is more complex than it may seem, and the debate should not revolve around golf vs. water. In reality, the latter is not wasted on the former, as technology now helps drive significant water savings in golf irrigation.
What Public Perception Is Missing
Golf is often considered a heavy water consumer, but numbers actually prove the opposite. In Arizona, golf course irrigation only accounts for around 2% of the state’s daily water consumption. By comparison, agriculture requires over 73% of the public water supply.
Additionally, golf is an indisputable source of income for the local tourism industry. The famous tournament WM Phoenix Open alone drives over 750,000 visitors to Arizona each year. These visitors are likely to spend, on average, almost three times more than regular tourists. This spending spans across different sectors such as hospitality, transportation, and other tourism-related services, thus supporting the local economy as a whole. In terms of economic impact, Arizona’s golf industry creates over 66,000 jobs and brings more than $500 million in tax revenue.
Finally, golf’s direct support for the community through charity contributions is also significant. For example, in 2026, the WM Phoenix Open tournament helped raise more than $20 million for Arizona charities.
While none of these factors exclude golf from sustainable water use conversations, they highlight that this sport’s impact in Arizona is more multifaceted.
The Truth Behind Golf Course Irrigation Today
One of the often overlooked aspects when discussing golf course irrigation is the water source. Nowadays, many golf courses in Arizona largely rely on recycled water for irrigation. For example, 23 courses in Scottsdale use water from the Reclaimed Water Distribution System (RWDS), and Tucson has been using a similar reclaimed system for golf course irrigation since the 1980s. These alternative water sources help save millions of gallons of potable water per year.
Furthermore, the United States Golf Association’s (USGA) $30 million water-resilience pledge also helps courses reduce water usage through smart irrigation technologies and strategies. This initiative provides a continually updated water-resilience playbook and funding for the research and adoption of emerging irrigation technologies.
Technology is now the key factor driving water savings in turf management. Golf course superintendents are increasingly relying on smart, AI-powered irrigation systems, satellite imaging, and soil-moisture sensors that gather weather and soil data and use it to optimize irrigation schedules. Smart irrigation means that each turf area gets the amount of water it needs only when necessary. The system calculates how much water is required based on humidity, radiation, turf stress, and other factors, so that each gallon that can be saved is indeed saved. Subsurface drip irrigation, which delivers water directly to the grass roots, also helps save up to 40% of the irrigated water. Replacing old turf varieties with drought-tolerant grasses such as Bermuda or Zoysiagrass is another measure increasingly adopted by golf courses to cut water consumption. According to the USGA, grassing changes can deliver water savings of 25% or more.
Today’s golf course irrigation in Arizona no longer relies on guesswork or fixed schedules. Many courses use AI-driven precision irrigation to tailor their turf management strategy and decrease their water use. These changes quietly happen in the background while the visible part, the lush fairways, continues to fuel disputes over public water use. Despite its bad reputation in terms of water consumption, golf has proven that sustainability and profitability are perfectly compatible. If anything about golf should trigger water-related debates today, it is how other industries can adopt similar measures to decrease water consumption.
