DRINKING WATER SYSTEMS 511
distance to a faucet or tank; perhaps he must wait his turn there,
and while he waits, he gossips a bit, usually to no good purpose.
If the supply is city reservoir water, he runs off a certain quan-
tity in the belief that he can get it cool; if it is tank water, it is
either too warm to be satisfying or, if iced, too cold to be healthful.
It is a well-established fact that the usual methods of drinking
water supply are wasteful to a high degree—wasteful of time and
water, conducive to ill health, and frequently responsible for a
good share of the peevishness and unrest so manifest among workers
in the warmer months of the year.
FIG. 224.—CORK PIPE COVERING ON THE LINES OF A REFRIGERATED
DRINKING WATER SYSTEM.
The Solution.—Progressive and well-informed managements are
in <strong>complete</strong> agreement with doctors on the important part that
drinking water plays in maintaining health, morale and efficiency
under modern working conditions. And thus the refrigerated drink-
ing water distribution system has come into extensive use. It
has been found not only <strong>complete</strong>ly practical and satisfactory from
the hygienic and the production standpoints, but actually cheaper to
operate than the cruder methods previously used.
This modern system is very simple both in principle and operation.
It consists of refrigerating equipment, an insulated water tank lo-
cated at the correct point, and properly insulated distributing lines
connected to sanitary drinking fountains conveniently and correctly
placed throughout the plant or building. It is readily adaptable to
any industrial requirements, and is elastic enough to be expanded or
contracted as future needs may require. With it a constant supply
of properly cooled water is instantly available, without waste or effort,
with no slop or muss, and at no risk of contamination from dirt or
communicable disease. Its operation vastly simplifies a problem
that has become more and more troublesome with the passing of
time, and which in many mill?, factories and public buildings is to-
day crying for solution.
