Waterfull advances military water resilience with larger 50-gallon variant

Waterfull Inc. is moving its AFWERX-backed potable water storage system toward a larger military-focused model after completing Phase I testing. The company is seeking Direct-to-Phase II funding as defense planners look for low-maintenance water resilience tools that can support installations and contested logistics.

Why it matters: - Military installations need reliable potable water when power, plumbing or supply chains are disrupted. - Waterfull’s system is designed to add water resilience without electricity, chemicals, pumps or moving parts. - A larger variant could help reduce dependence on bottled water deliveries and other logistics support.

What happened: - Waterfull Inc. said July 23, 2026, that it is advancing the Waterfull Barrel after completing a Phase I award through the AFWERX Open Topic SBIR program. - The Whittier, California company is pursuing Direct-to-Phase II funding to speed development for the Department of the Air Force and joint forces. - Waterfull is evaluating a 50-gallon military variant built on the validated 30-gallon design.

The details: - The 30-gallon Waterfull Barrel is a building-integrated potable water storage system. - The system ties into existing plumbing and uses passive daily circulation to keep water fresh. - During a power outage or municipal water disruption, the system shifts to gravity-fed delivery at the point of need. - Waterfull said the 50-gallon version raises engineering challenges tied to pressure management and structural integrity under heavier loads. - The company said it is assessing those limits while preserving the same passive, power-independent architecture. - The technology may fit fixed installations, forward operating locations and other facilities that need potable water on site. - The Waterfull Barrel has been third-party tested for material integrity, pressure performance and wind resistance up to 145 mph. - The system is NSF/ANSI 61 certified for potable water use. - The Waterfull Barrel is protected under U.S. Patent D843766. - Waterfull said it is looking to engage Air Force and Army organizations, installation stakeholders, defense contractors and other government partners. - The company also wants to support pilot programs and further SBIR Direct-to-Phase II development. - Waterfull Inc. says the Waterfull Barrel integrates with existing building plumbing to provide continuously refreshed potable water without electricity, chemicals, pumps or moving parts.

Between the lines: - The move to a 50-gallon military variant signals a push from proof of concept toward operational use. - The focus on distributed storage reflects a broader defense priority around installation resilience and contested logistics. - Waterfull is positioning the product as a complement to existing infrastructure, not a replacement for it.

What's next: - Waterfull will prepare its Direct-to-Phase II proposal. - The company is likely to seek defense partners for evaluation, pilots and additional development. - The larger military model will need to clear engineering and performance hurdles before broader deployment.

The bottom line: - Waterfull is turning a tested water-storage concept into a bigger military-ready system aimed at keeping potable water available when supply lines fail.
