National Standards.
1.-THE boards practice of installing
smaller standard sizes of fire by
drants at frequent intervals, rather
than large hydrants with numerous
outlets spaced at longer intervals, is
adopted generally in up to date works.
vehy generally fire MIGRANTS and gate
valves conform to the standard spec
ifcations of the American Water
Works Association, all parts Of
which are interchangeable, being the
same standards adopted by the board
four years ago.
Sterilization Of Water Supplies.
Passing to the, question of Ultra
ton. the use of extremely minute
quantities of chloride Of lime as used
at the local plant, has offered very
practical and simple solution OF the
sanitary troubles OF nearly every city
water supply. The value of chloride
Of lime for Strengthening out water
difficulties becomes manifest when 1t
is known that more than one hundred
of the larger cities use 1t success
fully. 1t has shown itself to fit in
with every situation and condition Of
water supply. New York City ster-
lilies the Croton water supply Of
3SO,OOO,O0O gallons daily, with sixteen
pounds per million gallons. Cleve-
land with a supply of one hundred
million gallons daily from Lake Erie,
likewise sterilizes with sixteen
pounds per million gallons. In To-
ronto where six pounds per million
gallons is used the water is reduced
as to bacterial count to point where
1t is absolutely sterile. The whole
supply in Montreal is sterllized with
chloride of lime at ratio OF from
five to seven pounds per million gall
Ions.
Thanks to this treatment, Cincin-
natl ranked most favorably in typhoid
rate IN 1912, among larger American
cities In Pittsbarg four pounds per
million gallons is used in connection
with slow sand filtration. Those who
are qualified to speak on the subject!
say that no reliable evidence has ever
been produced that this sterilization1
has anything but the most beneficial
influence on health.
From the foregoing it win be seen
that wherever municipal water sup
plies are very clear, as in the case of
the st. Lawrence river and Great
Lake region, they can be made per-
feet drinking waters by the use Of
chloride of lime; and that in cases OF
turbid waters this valuable agent fits
in with every established publication
system. 1t also must be concluded
that most small communities not pro-
vided with filtration have no choice
but to adopt this valuable sterilizingi
agent, even with somewhat turbid
waters.
ITO meet the growing demands Of
industrial consumers and other pat
rons for filtered water it will be nee
easary to increase the capacity OF the
Alter plant and install additional
pumping units, the original plans
having been drawn with the view OF
ultimately doubling its present ca
pacity, which may be accomplished at
one-half the initial cost.
The water board has contributed
freely Of It's time and practical bust
ness experience during the last four
years to the extensions and improve
ments in progress covering that per-
