The U.S. Army Tank Automotive Research, Development, and Engineering Center TARDEC and the Defense Advanced Project Agency DARPA are partnering to develop fundamentally new water technologies to reduce the logistics footprint and enable the development of a decentralized water support concept. The individual soldier requires 1.5 to 3.5 gallons per day to prevent dehydration. When personal hygiene, meal rehydration, and emergency medical treatment are included the daily planning factor becomes 4.1 gal per soldier per day. Current state-of-the-art water purification equipment can purify any source of water, but this potable water must then be transported from the source to the point of use on the battlefield. Without advances in water sustainment technology, water distribution is projected to account for 30 to 40 of the Objective Force daily sustainment requirement. TARDEC and DARPA are developing a range of revolutionary technologies for water recovery and generation. These technologies will produce water anywhere on the battlefield, thereby enabling the development of distributed water production systems to augment the soldiers water supply and significantly reducing the frequency and quantity of resupply. The technology will provide military units with a radically more mobile and flexible water production capability. The technology will enable future sustainment concepts allowing units to operate without external resupply for 3 to 7 days.
