The herald-advance. (Milbank, S.D.) 1890-1922, 1904-01-08

800 feet of four inch cast iron pipes
are included in the estimate. This
makes something over two miles of
watermains. together with hydrants,
special castings, valves and boxes
are estimated at a total cost OF S1l, 9l3.

No mention is made in the report of
the watermains already laid on Main
street. and from the maps submitted
it would seem that the cost Of the
mains on Main street should be deduct
ed from the above estimate. Those
mains are eight inches in diameter,
and can be used and made a part of
the new system.
SEWERAGE SYSTEM
There are two general systems of
severance Ollc hIlOWh 90 YIN y
system and the other as the combined
system. The separate system Is where
the sewers carry off the sewerage
proper and the storm water Is earned
off by open cutters or independent
underground drains. In the combined
system the sewers are designed to
carry off the sewerage and the storm
waters in the same pipes. The sep
arate system is claimed to be better
adapted to the smaller towns and
villages where are no paved streets
and the surface of the ground is sandy
and where the dirt will easily wash
into the ewers, and also on account
of the size of the pipes required to
carry off the sewerage as they Will
permit of frequent and efficient flush
ing. 1t is probable that the combined
system ear be constructed at a less
cost than the separate system, but the
estimates in the report are all based
on the cost of the separate system,
which is also thought to be better in
the event that it might be necessary
to install a system for the publication
of the sewerage, consisting of a septic
tank, followed by alteration. 1t is
suggested that this matter need not be
considered in the present plans, except
for fixing the grade for the main
sewers, as the waste, in the opinion OF
the engineer, a be emptied into the
MILESTONE without inconvenience or
injury to anyone.
The portion of the city south of the
railroad is naturally divided into two
drainage districts. The smaller dis
trict comprising the are north OF
Fourth avenue and west of Fourth
| street, which includes the pond or
block l3:the larger district comprising
the low ground along Sixth avenue
and Sixth street and the adjacent terri
tory. In each of these districts the
mains for both the sanitary and storm
system must be carried along the
same lines and about the same depth
which are shown on the maps accom-
panying the report.
The mains for the first district men
toned will commence at the intersec
tiOn of Third avenue and Secon(
street andrun north to Railway avenue
thence east to Fourth street, theme,
north across the railroad track IL
the center of Milbank avenue, from
which point the storm water sewer
will continue directly north to thu
creek and the sanitary W will b.
carried east to connect with the mali
sewer from the second district on tn,
north and south quarter line.
In the second district the main will
commence at the intersection of MAR
street and Sixth avenue and rul
thence east to Fifth street, thenc'
north to Fourth avenue and thence cas-
md ronth olnnr tho m n pfnfp lin
to the creek. The elevation of tn,
high enough to permit of extending
the sanitary sewer further down TIN
stream whenever conditions SO require
For the present the sanitary sewer
can be safely discharged at the Quite
on the quarter line, and if abso
lutety necessary to reduce the frs
cost the sanitary sewer from the frs
district can be temporarily discharged
at the foot Fourth street, thus savin,
the cost of extending it east acros
unoccupied property to the quartz
line.
With the main sewers completed
the construction of laterals will b
comparatively easy and inexpensive
! The lateral sewers, with but few excep
tiOns, would be eight inches in diameter
which is the minimum size that shout,
be used for a street sewer. The ave.
age cost of the lateral sewers, includ
ing man holes, flush tanks and othe
appurtenances would be about eight,
cents per lineal foot or forty cents pc
front foot for each side of the street
The cost per fifty foot lot for tn
lateral sewers would, therefore, aver
age about twenty dollars, and If thi
is permitted to be paid in installment
with interest on deferred payments, j
would not be a burden to anyone.
If it is beyond the means of the cit,
to construct the sewers in both dis
tricts it is recommended that tn
sewer be constructed in district nun
Der one, and that will accomplish tn
most good and furnish an outlet TO
the greatest number.
