Waterfull advances AFWERX-backed water resilience tech with larger military variant

Waterfull Inc. is moving its AFWERX-backed potable water storage system toward a larger 50-gallon military version after completing Phase I in the Open Topic SBIR program. The company is now seeking Direct-to-Phase II funding to support installation resilience, mission assurance, and contested logistics for Air Force and joint-force users.

Why it matters: - Military installations need resilient access to potable water when power, pipelines, or supply chains are disrupted. - Distributed, building-integrated storage can reduce dependence on bottled water deliveries and other logistics-heavy emergency responses. - Waterfull’s approach is designed to deliver water 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-focused variant of its patented Waterfull Barrel. - The announcement was made from Whittier, California, on July 23, 2026.

The details: - The existing 30-gallon Waterfull Barrel integrates directly into building plumbing infrastructure. - The system uses passive daily circulation to keep stored potable water fresh. - During a power outage or municipal water disruption, the barrel shifts to gravity-fed delivery. - The larger 50-gallon version is being evaluated to better meet military storage needs at the point of need. - Waterfull is assessing pressure management and structural integrity as capacity increases. - The company wants to preserve the same passive, power-independent architecture in the larger unit. - 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. - The system is protected under U.S. Patent D843766. - Waterfull says the technology may support fixed installations, forward operating locations, and other facilities where potable water access is critical.

Between the lines: - The military interest points to a broader shift toward infrastructure that can function during contested logistics and utility disruption. - A larger-capacity version suggests Waterfull is trying to move from a validated concept to a deployment-ready defense product. - The main challenge is scaling storage without compromising the passive design that makes the system useful in emergencies. - The focus on installation resilience signals that water security is being treated as part of mission assurance, not just facility maintenance.

What's next: - Waterfull is preparing its Direct-to-Phase II proposal. - The company is seeking engagement with Air Force and Army organizations, installation stakeholders, defense contractors, and other government partners. - Waterfull is open to pilot programs and additional development under the SBIR Direct-to-Phase II pathway. - The company expects the work to continue around military applications, including installation and forward-location use cases.

The bottom line: - Waterfull is trying to turn a passive potable-water storage concept into a larger defense-oriented resilience tool that can support operations when conventional supply systems fail.
