Water technology firm, Water Harvesting Inc. (WaHa), has secured $8 million in Series A-1 financing as it looks to scale the deployment of its atmospheric water generation (AWG) systems across the Gulf region and beyond.
The fundraising round was led by Chairman Mike Phillips and board member Christian Thirion, with additional backing from institutional investors including Berkeley Catalyst Fund, Anthropocene Institute, Vestafund, and Japan’s Mitsui Mining & Smelting Co., Ltd.
The funding eliminates WaHa’s outstanding debt and simplifies its capital structure ahead of a broader commercial push, including new partnerships and a forthcoming product launch at WETEX 2025 in Dubai.
WaHa’s proprietary technology, branded as the WaHa Vaporator®, has demonstrated exceptional performance in arid and off-grid environments. Field trials in Abu Dhabi, Riyadh, West Texas, Stockholm, and a remote UAE desert site have achieved 99.998% mechanical reliability and delivered 98.3% of targeted water output, marking what the company claims is the highest sustained performance in the AWG industry.
“Our systems are purpose-built to withstand the harshest climates,” said Mike Phillips, Chairman of WaHa. “This new investment enables us to rapidly expand our reach in the GCC and strengthen water security across key sectors.”
The company’s field trials at Khalifa University in Abu Dhabi have shown its technology can consistently extract potable water under extreme heat, low humidity, and frequent sandstorms, conditions where most AWG systems struggle.
CEO Frank Ramirez added: “We’re now in active negotiations to establish commercial manufacturing, distribution, and long-term service agreements. This is a pivotal step in delivering sustainable water solutions where they are needed most.”
WaHa holds 14 patent families and 18 granted patents worldwide. Its modular technology is designed for integration with HVAC and agricultural systems, and is well-suited for utility-scale, industrial, and off-grid applications.
The first commercial unit will be unveiled at WETEX 2025 (September 30 – October 2), where WaHa aims to attract interest from utilities, developers, and industrial operators seeking to decarbonise water supply chains and bolster resilience.
