At WaHa, we believe the future of water security lies in the air we breathe. Today, we announce a milestone.
We have officially partnered with the Arizona Atmospheric Water Harvesting (AzAWH) testbed at Arizona State University, one of the leading facilities dedicated to accelerating real-world deployment of atmospheric water technologies. As part of this collaboration, our advanced WaHa Vaporator® has been integrated into the AzAWH testbed, where it is now undergoing rigorous, independent evaluation in authentic desert conditions.
Why This Partnership Matters
Arizona’s desert environment is one of the most demanding proving grounds on Earth. With extremely low humidity, intense solar radiation, and minimal rainfall, it mirrors the water-stressed regions where decentralized water solutions are needed most.
The AzAWH testbed’s mission to speed the development and commercialization of water vapor harvesting technologies aligns with WaHa’s goal: making pure water accessible anywhere, regardless of traditional infrastructure.
By placing the Vaporator® in this real-world laboratory, we are validating performance in the field.
Real-World Results
Initial performance data from the AzAWH facility shows:
- At just 18% relative humidity, typical for arid desert conditions, the WaHa Vaporator delivered its full specified output of 24 liters of pure water per day.
- This is not a reduced or lab-optimized figure. It is the exact production rate the system is rated to achieve.
- The Vaporator is engineered to operate reliably in air as dry as 7% relative humidity.
These results demonstrate that the Vaporator with a novel solid desiccant recognized through the 2025 Nobel Prize in Chemistry performs exactly as specified under the harsh, variable conditions found in real desert environments.
The Technology Behind the Results
The WaHa Vaporator uses a novel solid desiccant to capture water vapor even when humidity levels are extremely low. Unlike older atmospheric water technologies that struggle below 30–40% RH, our system maintains high efficiency and output in the driest conditions.
This capability matters for regions like the American Southwest, the Middle East, North Africa, and parts of Australia and Central Asia. These are places where water scarcity is acute and conventional solutions are expensive or environmentally costly.
A Shared Vision for Water Security
This collaboration represents more than a successful test. It is a validation of atmospheric water harvesting as a scalable complement to traditional water sources.
Together, WaHa and AzAWH are proving that we can harvest water from the atmosphere in the very places where water is scarcest, turning one of nature’s most abundant resources (air) into a reliable supply of pure water.
As climate patterns shift and populations grow in arid regions, solutions like the Vaporator offer a decentralized, low-impact path forward that doesn’t require new dams, pipelines, or desalination plants.
What’s Next
The integration of the WaHa Vaporator into the AzAWH testbed is just the beginning. We will continue working closely with Arizona State University researchers to gather long-term performance data, optimize system efficiency, and explore new deployment models for communities, agriculture, and humanitarian applications.
This partnership supports development of the technology and broader adoption of atmospheric water generation worldwide.
Pure water generation in arid conditions is no longer theoretical.
It is performing as designed in the Arizona desert.
