“Anytime there is a natural disaster, [Project Manager] Force Projection gets a call asking ‘What can you give?’ When disaster strikes, water is usually the first thing that is destroyed,” said Project Manager Patricia Plotkowski.
Potable H2O—A Soldier’s Necessity
All of the Army’s water purification sys- tems use RO as the primary method of treatment, and the purification systems work on the same basic principles. A raw water pump is used to draw water from any source, fresh or salt water. The water is delivered to the system where it enters the “pretreatment” filters. “This is where all of the suspended solids are removed,” added Plotkowski.
From there, the water is delivered to a high-pressure pump where it is pressur- ized enough to overcome the osmotic pressure of the RO membranes and all of the dissolved solids are removed. If nuclear, biological, or chemical con- taminants are present, the treated water enters a series of activated carbon and resin exchange filters, which work to remove those contaminants.
“After that, the water is delivered to a product water storage tank where cal- cium hypochlorite is added to disinfect the water. Enough disinfectant must be added to maintain a constant and adequate residual,” said Schulkins.
The EWPS can reliably produce 600–700 1-liter bottles per hour. In theater, the EWPS produces more than 500 bottles of water per hour and operates 6 days a week. (U.S. Army photo.)
The Army’s PM PAWS is revolutionizing the battlefield, providing the most critical necessity to our Soldiers.
The water is checked for quality assur- ance to ensure that it is potable and safe for Soldiers. Strict water quality is directed by the U.S. Army Public Health Command.
The initially deployed EWPS produced more than 1 million 1-liter bottles of water without any incidents of quality. “Soldiers in Iraq said the best thing the Army could have done was get [them] bottled water,” added Mayfield.

Keeping our warfighters hydrated is imperative to the success of missions— both day-to-day operations and while in combat. The Army’s PM PAWS is revolutionizing the battlefield, provid- ing the most critical necessity to our Soldiers. PM PAWS is managed under the leadership of Project Manager Force Projection within Program Executive Office Combat Support and Combat Service Support (PEO CS&CSS).
