millions per diem.
Fifth, The statement that water can
not be filtered except by mechanical
filtration is no part of this question
as Mr. Underwood has not made any
proposition to filter the water except
by mechanical filters.
Sixth, In regard to the new building
to be erected, that it will be attract
i've and will be where it will show and
advertise the city; the committee will
simply say that we do not think that
the people of Ottumwa are desiring
waterworks for the advertisement it
will furnish, but for the purpose of
furnishing sufficient supply of clean
water for culinary purposes and of
capacity to furnish water for fire pro-
lection at present and what might be
expected to be needed in the future.
Seventh, In regard to the PROPOSE
ton to take water from the head race
and that water taken therefrom is bet
ter than that taken above the dam;
your committee will say that the state
ment that water taken from the race
near the pump house is better than
water taken from the river above the\
dam and above where any sewerage
enters the river is not correct, except
possibly during extraordinary high
water.
Eighth, In regard to the high SER
vice station the committee will say
that we do not believe that the people
living on Court Hill are interested in
the manner the water is furnished to
them, but only that it is furnished at
pressure sufficient to give them pro-
per service.
Ninth, In regard to the danger of
having too much pressure at hydrants
the committee will say that there is
no proposed increase in pressure be-
yond pressure from the reservoir for
| fire protection for the business and
manufacturing districts the commit
tee will say that from past expert
ence the pressure will not be sufficient
| in the future.
improvements.
The proposed improvements of the
pipe lines, the committee will not take
time to report on each pipe in detail
as presented by Mr.. Underwood, but
will inform the council what we find
this to amount to as a whole. The
plans call for about 1892 tons of stan
dard weight cast iron pipe and about
twenty-five tons of specials with the
necessary gates and proposed eighty
three additional fire hydrants.
In regard to the pipe to be laid we
will state that we do not think that
standard pipes as proposed to be laid
and pipe now laid is of sufficient
strength to stand the fire pressure
needed IN the future in the business
district of the city. Manufacturers of
pipe recommend this grade of pipe
for eighty-siX pounds pressure, while
pipe four and six inches in diameter
of this grade will be perfectly safe for
twice the pressure they are recon-
mended. 1t would not be the case with
the larger pipes where the factor of
safety is much smaller.
Clear Water Basin.
The porposed clear water basin is
necessity for any waterworks plant
that filters it's water, yet while the ba-
sin will have a capacity of only $780,
900 gallons, still we recommend it as
good improvement.
Sedimentation Basin.
| This improvement we consider over
estimated in it's capacity for filtration;
the Jewel filter with two additional
tanks will have capacity of 2-2-3
million gallons per diem. Mr.. Under
wood states that when the plant is
completed as proposed. he will be able
to thoroughly filter 4,500,00O per diem
In this statement we believe Mr. IN
derwood to be mistaken because we
have seen sedimentation tanks or bas-
ms, at other waterworks plants and
consider them great aid in getting
heavy sediment out Of the water be-
fore 1T enter into the regular filter.
With the sedimentation basins and adj
dition to the Jewel filters as proposed
We believe that when the water in the
river is in a turbid condition, 2-2-3
million gallons per diem will be as
much as they can filter.
Pumping Capacity.
i The present pumping capacity of s.
100000 gallons per diem, which Mr..
Underwood does not propose to in
crease until the consumption reaches
i an average of 600 nm gallons nor
