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,
