Water Conservation Technologies
The Las Vegas Grand Prix is setting a new standard for water management at major sporting events by implementing cutting-edge technologies. These initiatives not only reduce water use but also create alternative water sources, replacing traditional systems that consume significant amounts of water. At the heart of this effort is the event's commitment to a net-zero water strategy.
The Grand Prix relies on two key technologies to achieve this: atmospheric water generators (AWGs), which extract water from the air, and dry-cooling systems, which eliminate the need for water-dependent cooling methods.
Atmospheric Water Generators (AWG)
AWGs work by pulling water vapor from the air and converting it into drinkable water.
In November 2023, the Las Vegas Grand Prix collaborated with MGM Resorts International, the Southern Nevada Water Authority (SNWA), and WaterStart to install a $400,000 atmospheric water generator at the MGM Grand. This system captures water vapor from an evaporative cooling tower, condenses it, and recycles it, turning what would have been wasted water into a valuable resource.
In its first year of operation, the AWG produced 230,000 gallons of water. This offset nearly 30,000 gallons used for cleaning the track and provided enough water for the Grand Prix Plaza's needs.
"That's 200,000 gallons less that came out of Lake Mead...We've all generated … more water than anticipated", said Michael Bernardo, Enterprise Conservation Division Manager for the water authority.
This technology addresses a critical issue in Las Vegas, where cooling towers are among the largest water users. By capturing moisture that would otherwise be lost, AWGs make a significant impact on water conservation.
"When major companies like F1 are willing to invest in new technologies such as atmospheric water capture and recycling, they can help prove - and improve - these technologies and make them more widely viable on the market", said Elizabeth Koebele, Associate Professor at the University of Nevada Reno.
Equally transformative is the adoption of dry-cooling systems, which further enhance water-saving efforts.
Dry-Cooling Systems
Dry-cooling systems complement AWGs by completely eliminating water use in cooling processes. Instead of relying on evaporation, these systems use air to dissipate heat, making them far less water-intensive.
At the Grand Prix Plaza, dry-cooling systems replaced evaporative systems, saving an estimated 3 million gallons of water each year.
"While the Las Vegas Grand Prix could have installed evaporative cooling before the moratorium, they made the conscious decision to install a dry-cooling unit that does not consume water...Using dry-cooling technology at the Las Vegas Grand Prix Plaza building saves an estimated three million gallons or more per year", explained Bronson Mack, Public Information Officer at SNWA.
Although dry-cooling systems require more electricity and space, and produce water at temperatures about 10°F above ambient, their water-saving benefits are invaluable in a state like Nevada. Moving away from evaporative cooling - responsible for about 20% of water use at some Las Vegas properties - is a major step toward conservation.
These technologies prove that conserving water doesn't mean compromising performance or comfort. Instead, they demonstrate how smart engineering can turn environmental challenges into sustainable solutions.
