them from being cleaned or from
operating at all. Concrete vaulting
with earth covering would be best kind

basis of what I would recommend il I

plant with maximum capacity OF 5000, :
OGO gallons daily. The storage reser-
yoir would be necessary part of filter
plant here unless filter beds were twice
as large as has been proposed. This is
because pumping is all done in half Of

slow sand filter in this city at s9l,97l"
At the opening Of the afternoon ses-
sion. Engineer Hazen OF New York. re-
sumed the stand: Have estimated
the total cost of operation of such a fill
fer. plant Of $3,305. This does not in
clude taxes or interest. The deprecia-
ton Sl,OS5, covers replacement of plant
in 40 wears. Parts of physical plant
would doubtless last longer than that.
Have estimated cost of mechanical fill
ter plant here at s65,225. Have built
two plants almost exactly like one pro-
posed here. This would cost $3.50
yearly to operate. the depreciation be
ing 81 go of this total. More skill is
required in operation than in sand fill
ter. This plant requires much less
area. For a cOagulent have allowed
IA grains of alum per gallon. Have
estimated useful life of such a mechan-
citation accordingly. Think Mr.. Vests
La af oil a lf.-ys
plant here is not much different than
mine. The area of the filter plant here
now is given us 100 square feet. Water
absolutely free from pollution is very
rare
On cross examination: would ex-
pect good filtration plant to romove 9S
to 99.5 per cent. of bacteria from water.
Should expect from 20 to 200 bacteria
per cubic centimeter in filtered water
here. The number of bacteria in wa
ter is not a safe guide as to quality.
Think the good and bad bacteria would
be eliminated together. Do not know
that typhoid bacteria are larger than
others, or that they would be filtered
out sooner than others. The ultimate
test of water is the health of the COM
munity. and the death rate which falls
after filtered water is introduced"
Mr.. Leland, being called ON re-cross
examination: IF Togus put in a plant
of it's own it would have to have {:
,, steam pump to pump the water. Have
not figured how much coal would be
required. Probably about 1900 pounds
daily. About 10 to II horse power
would be needed to lift the water to re-
Quired height there. Should think coal
there would cost $3.50 or S. per ton.
Did not allow for engineer or fireman.
as | assumed steam would be kept up
there anyway. Made no allowance for
superintendent or repairs
On redirect examination: There
is Il large steam plant at Togus now
and no additional labor would be re-
quired to run water pump. They re-
pair their own services there now.

f. +. Lewis. chief engineer at Togus,
was next called: Have been at Togus
Is years. Designed all the buildings at
Togus. Keep a pressure gauge near
the boiler house. Its record is taken
eight times each day. In January the
highest pressure was Al pounds. On
several days it reached 40. The low
est was 90 pounds on Jan. Z. In Feb
ruary the highest pressure was 43
pounds on Nthe 22d. The lowest was 30
pounds. In March the highest pressure
reached was As on the 10Th and eth,
and the lowest was 26 on the 10th.
When we run the pump we draw water
from Greeley pond and put it through
the whole system. Have to have Il
pressure of 40 pounds to give water on
upper floors of buildings. With this
pressure there would be no efficient fire
service without starting pumps. For
fire purposes OH upper floors 80 pounds
is needed. The consumption at TOguS
is 100000 gallons daily. The pipe
whose waste has been testified to
comes from the steam condenser 1t is
a necessary part of heating system.
1t is Pinch pipe. There is no head to
the water escaping there. Half the
opening into this pipe is closed. By
measurements we found that the os-
cape here would amount to about $4,000
gallons i'm "a hours. This only occurs
i'm winter months. 1t is a wasted water
because it has been used once in heat
ing system. In summer the water
pressure at LOCUS is very SATISFACTORY,
The fountains in the summer offset use
of water in heating in winter. At 40
pounds pressure there are seven feet
| of water in standpipe. At 59l. pounds
pressure the standpipe is full"
On cross examination: DO not think
amount of water used while measure
ments were made was less than usua l..
The closets flush automatically every
| five or eight minutes. | inspect these
every week. If there is waste there it
will be the same throughout the year.
| Do not know what Mr.. Shedd may have
| seen as regards the waste pipe from the
boiler room. There is never force
enough to throw water over roof of
| highest building at TOgus. Do not re-
member ever telling Mr.. Shedd that
such q stream could be thrown. Can
