in Europe. Was personally connected
with work on filters at Berlin. Such a
filter removes - Fer cent. or more OF
the bacteria. In Germany the govern
mcnt requires filter plants to purify
water so that Il cubic centimcter shall
not contain over 100 bacteria. The
plant such as ] have estimated here
would be of that efficiency.
Il have estimated cost of storage

Ssh! 400. TO this | have added II per

rate Of consumption.
Also considered the cost and lo>a-
ton OF mechanical or rapid filtration
plant here. 10 not consider this so
well adartod 10 the soft water of this
river. such i tlter works 40 times
faster than Il SLOW sand filter. ana the
chemical used is alum which causes
the bacteria to gather in masses. If
water is lacking in alkalnity, as this
water is. line must be used.

but much safer"

Redirect: BY useful life of filter |
plant | mean its period Of efficient and |
economical service. 1t is Il business
proposition to put aside ] sum each
year fer Il fund to replace the plant
when the advance of science gives bet
ter methods of filtration. Already cN-
pcrimcutS are being made to purify
water by use of ozone ana also II"
electricity. An illustration of what |
mean by uScfu! life Of a filtration plant
is shown in the existing filter plant OF
the Augusta Water Company. which IS
now useless from sanitary standpoint
after Is wears Of service. If Il sum had
been put aside each year for d"prcCla-
tirn. the Water company would hay"
hal Il good sum HOW toward modern

posed plant would accomplish tn ~
