The Small unit water purifier is a developing requirement in the Department of Defense. There is a current gap between the small scale Individual Water Purification Systems (IWPS) and the larger Light Weight Purification Systems (LWPS). The Small Unit Water Purifier (SUWP) fills the gap for company or platoon size teams that must go out in austere environments. The SUWP averages 15 gallons of purified water per hour from any salt, brackish or salt water sources. Taken in the summer of 2014 the video of Cpl. Colby Wallace, a water purification technician with Combat Logistics Battalion 3, and a 22-year-old native of Cape Coral, Fla., explains what the Small Unit Water Purification (SUWP) system is and how it operates. The SUWP was part of the Marine Corps Warfighting Lab’s Advanced Warfighting Experiment during Rim of the Pacific (RIMPAC) Exercise 2014.
