The Navy operates several water treatment facilities at remote installations around the world. Water contingencies at these locations can result in significant risk to personnel, loss of mission capability, and cost to recover. This study considers the feasibility of employing mobile desalination systems to support water contingencies at remote Navy installations. Most Navy installations that currently produce their own potable water do not have simple, reliable backup systems to sustain production if a water plant becomes inoperable. This study considers the viability of developing, strategically pre-positioning, and maintaining such assets, making them available to provide potable water from various water sources including ocean desalination and brackish water in support of global water contingencies. This study will also determine the risks associated with the greater NAVFAC community in the absence of such contingency assets, and will conduct a risks and benefits analysis to determine total costs, benefits, and risks associated with having such a system pre-deployed versus continuing at the current state with no such response capability.
