INTO THE SEWER AGAIN.
Another Report on the Best System
to Adopt.
Civil Engineer Maddox Submits
Plan on Request 80 Com
pared With Others.

Some weeks ago Mr.. Healy, a member of
the sewer committee who; has taken much
interest in that question, invited Mr.. H.
S. Maddox, civil engineer of Chicago.
who had charge of the construction of the
| Rock Island through the county to take
| the data already owned by the city on
| that question and figure on the sewer
question. Mir. Maddox has had CON
siderable experience IN that line of
engineering and has spent over a week
making estimates, which are the result OF
an examination of all the data on hand
! and some more gained by himself with in
struments. He figured on the part of the
city between Fifth avenue and the river
and Thirteenth to Lincoln street. He com
pleted his report Tuesday evening and a
summary Of the same is as follows:
Rosewater G. Christie's plan is gravity
system, which will cost as follows:
Cost of main sewer. S 65, $685. 60
Cost OF laterals and flush tanks. 1901. 80
forty-six flush tanks, 800 gallons
per day, require 1880 gallons
at 5 cents per 1000 gallons. or
90 cents per day. which at 6 per
cent interest is equivalent to
an investment Of. ............ 4,1s3. SO
And would require capital of...s149, O72. SO
No surface water can be admitted into
this system and in a number of places the
surface will have to be raised to put in
flush tanks, as they come too close to the
surface.
The main put In for this section of the
city will answer for that portion OF the
city east Of the Santa Fe railroad.
The plan suggested by Mr.. Maddox is
to construct the main sewer On Market
street and keep just above the quicksand
and follow the grade of the quicksand,
which is about four feet per mile, sub
mains to be placed in alternate north and
south streets, and laterals in each block;
the sub-mains TO be on a grade sufficient
to secure velocity Of two feet per second
for the sewage. When the sub-Inains
reach the Quicksand they are drawn to-
gether and the sewage is discharged into
the main on Market street and another set
of sub-mains are started. In this manner
system of sewers is obtained which are
self-cleansing as far as relates to sewage
a portion of the surface water can be ad
mitted into these sub-mains, and as
the street washings have a tendency
to harden in the sewers, the sub-mains
must be flushed. For this method the
cost of laterals will be ..........s f., 994
Cost of mains OBSERVATION-DISCLOSURES. 1913.
Total cost sll4, 346
To this will have to be added the cost of
securing water from either Chisholm creek
or bac it TOW lie rt,cl No
sub-mains, at present about 10000 gallons
of water would be required daily, for
which the water company would charge
so cents per day.
Pumping sewage is another method to
secure grades. BY this method the later
ais would cost 43,994-the same as the
other. There would be three pumping
stations each costing $4,000, or for the
three $4,000. Coal, wages of engineer,
etc, for each station would be at least
81, 500 per year, representing at 6 per cent.
an investment of $4,000 for one station:
for three would be s15s.0O0. The iron pipe
necessary to carry the sewage to the river
south Of the city would cost about $780, 600.
The total capital represented would be
s279, $685.
The laterals Of each one of these meth
DDS will require some attention, how much
can not be estimated, but it will be a small
amount The system proposed by Rose
water e. Christie, on account Of their
grades being lighter, would naturally re-
quire more attention.
Although the grades of each plan are
twice as great as by Rosewater & Christie's,
still they should be flushed occasionally, !

The West system has its friends in the
city, and it is used at Atlantic City |
which has some points in common with |
Both are on a sandy soil. Both |
are underlaid with water. AS the water |
rises in the Atlantic ocean, either by the |
tide or from storms, it also rises in the soil |
Of Atlantic City.
AS the water in the Arkansas river rises. !
so rises the water in the soil of Wichita.
But right here the similarity stops. At |
Atlantic City the water rises at level all |
over the city.
In Wichita the water rises on an inclined |
plane, having the slope of the Arkansas
river; the slope Of which is sufficient for
main sewer. And right here comes the
point, the sewerage Of no two towns can
be carried out on the same plan; each city
/. a separate study in itself.
BY either the pumping or the plan pro-
posed grades TO make sewers self cleaning
AN be secured.
But the pumping system will not care for
Any storm water, while the other plan
will Storm water is quite Objectionable
md should in this problem receive some
attention"
