Peak Period Population Calculated Daily Per Capita Usage (Gallons) Distillation of water on a relatively large scale was generally the result of development for the armed forces during World War II, and although present day equipment is greatly improved over wartime equipment, the vagaries of certain of its imperfections result in interruptions of service which rendered difficult the maintenance of the actual production rate of distilled water at or near the theoretical rated capacity of the installed plant. In the final stages of the Project, when the influx of popula- tion exceeded all anticipations, it was necessary to reservice and reuse all of the advance base type distillation units that were available at the site and which had previously been used by the military and by early contingents of the civilian construction force. Eight were installed at Eniwetok, eighteen at Parry, two at Runit, three at the Aomon Group, and four at Engebi. These old units were sub- ject to frequent mechanical failure and required considerable attention and maintenance; consequently total production from these units was far below total rated capacity. But the net production of these units enabled service to be maintained during these periods of extreme overload, Additional service through this additional mented concrete water storage was also necessary to maintain adequate the peak period at experiment time, On Parry Island, storage was provided by the construction of a canpartsurface storage reservoir having capacity of approxi- 9-195
