The Oskaloosa herald. (Oskaloosa, Mahaska County, Iowa) 1885-1919, 1903-09-03

J, recommended that there should be
two systems for the whole city. The
cost Of constructing sewers Of abe
J quate capacity to take all OF the
storm water falling on certain area
is many times the cost Of construct
ing sewers necessary to remove only
the sewerage proper of that area.
All parts Of the city should be sup.
piled with sanitary sewers, but with
the exception OF the comparatively
hat parts Of town and those parts
where the concentration of storm
\ water might do serious damage, it
would be unwise to attempt the con-
struction of complete system of
/ storm sewers. In many parts of
town, thanks to the fine natural drain
age, the storm water can be quickly
carried on the surface to the nearest
natural outlet. The cost Of carrying
the storm water under ground in tho
streets would be out of all proper
ton to the benflts to be derived.
Old Sewers.
The designing Of a system of sew
erage for the City of Oskaloosa is
much complicated by the fact that
there are in existence a great many
sewers. These sewers have been
built from time to time without much
regard to plan or thought of the fu-
ture. The location, size, grade, ca
pacity and condition of many Oh
| these are unknown. However, so
much money has been spent in the
construction of these sewers and so
many connections have been made
Herewith, that their existence can
not be ignored in preparing plans for
new ones. Although from the stand
point OF sanitary engineering these
sewers have many defects, all Of
which will be pointed out and recon-.
mendations for their improvement
made in later report, it is proposed
to make use Of these old sewers as
much as possible and incorporate
them into the Sanitary system. This
will be done only with the idea that
ultimately the defects they now have
will be remedied ami that storm wat
er now carried by some of these sew
ers will be finally excluded, when
other sewers now proposed shall have
been built.
Storm Sewers.
1t is proposed to build new storm
sewers for the business part of the
city and parts where the fall per
block is comparatively small. These
parts of the city it is proposed to
drain by. the following mains:
Third Avenue Main, extending from
H street to Fourth street on Third
avenue, with branches running north
ward and draining the territory be-
tween and including High avenue and
Third avenue as far east as Third
street and the blocks between High
avenue and B avenue and F and D
streets.
H Street Main will drain all that
part north of Third avenue west of F
street south of e avenue and east of
I street, with branch in street be-
tween High avenue and B avenue.
The H street main and Third avenue
main will unite and discharge into
the ravine near Fourth avenue and I
street. ...
Sixth avenue main, discharging in
to the rayine near First street south
of the c., r. I. & P. Ry., draining the
territory north of the c., r. /. &c p.
Ry, west of Eighth street extended
south of Third avenue and east of
Market street. To relieve the longest
ion of water at intersection of High
avenue and Sixth street, a storm sew
err can be constructed on Sixth street
with branch on Second avenue
from Sixth street to Fifth street.
In the parts of the city reached by
these mains the water can be taken
off the streets at the block corners,
or at intermediate points. Storm
sewers on B avenue from G street to
A street to combine at Market street
with storm sewer on G avenue COM
ing from Z street, will be continued in
a northeasterly direction to junction
with a storm sewer coming from ID
street near F avenue. Combining
these two and continuing the main in
northeasterly direction the storm
water can be discharged at the juno
ton Of the east and west ravine with
the ravine coming from north Sixth
street.
BY means of these sewers inter
secting the north and south streets in
the northern part Of town, the water
can be carried on the surface OF the
streets and withdrawn before con-
centrating into too great volume
AMI without being discharged on pri-
vate property. In this way all other
parts Of the city not included in the
| areas to be drained at every block,
