Waterfull advances military water resilience with 50-gallon variant

Waterfull Inc. is moving its AFWERX-backed water storage technology toward a larger military-focused version after finishing Phase I in the Air Force’s SBIR program. The company says the 50-gallon variant could help military installations and other sites maintain potable water access during outages and contested logistics disruptions.

Why it matters: - Military installations need reliable potable water to support mission assurance and resilience when power or supply chains are disrupted. - A distributed, building-integrated system could reduce dependence on bottled water deliveries and other logistics-heavy emergency water solutions. - Waterfull’s technology is designed to keep water available at the point of need without electricity, chemicals, pumps, or moving parts.

What happened: - Waterfull Inc. completed Phase I under the AFWERX Open Topic SBIR program and is now pursuing Direct-to-Phase II funding. - The company is developing a larger 50-gallon military variant of its patented Waterfull Barrel. - The announcement was dated July 23, 2026, in Whittier, California.

The details: - The current 30-gallon Waterfull Barrel integrates directly into existing building plumbing infrastructure. - The system uses passive daily circulation to keep potable water fresh. - During a power outage or municipal water disruption, the unit automatically shifts to gravity-fed delivery. - The larger 50-gallon version is being evaluated for pressure management and structural integrity under higher loads. - Waterfull says the goal is to preserve the same passive, power-independent architecture while increasing storage for military needs. - The technology has undergone third-party testing for material integrity, pressure performance, and wind resistance up to 145 mph. - The Waterfull Barrel is NSF/ANSI 61 certified for potable water use. - U.S. Patent D843766 protects the system. - Waterfull says the technology may fit fixed installations, forward operating locations, and other facilities where potable water access is essential.

Between the lines: - The move from a 30-gallon to a 50-gallon version suggests Waterfull is trying to move from a validated concept to a configuration that better matches defense use cases. - The emphasis on passive storage reflects a broader military push to reduce dependence on vulnerable supply lines and maintenance-intensive infrastructure. - Contested logistics has become a key design constraint for defense technologies, and water storage is part of that problem set.

What's next: - Waterfull is preparing a Direct-to-Phase II proposal. - The company is looking to engage Air Force and Army organizations, installation stakeholders, defense contractors, and other government partners. - Waterfull is also seeking pilot programs and further development opportunities under the SBIR D2P2 pathway. - The company says direct engagement is welcome from defense organizations interested in evaluating the technology for military use.

The bottom line: - Waterfull is positioning its patented water storage system as a low-maintenance resilience tool for defense users that need potable water even when electricity and supply chains fail. - More information
