L. 1t is claimed that where sewer
No. "a joins sewer No. IA that the
| stub is about Is inches higher than
soundings and profile would indicate,
and as a. consequence in joining on to
| this stub 1t raised 1885 feet of ring
| and ring brick sewer Is inch es high
er than called for by the profile; or, in
1 other words, il is claimed that said
1886 feet of sewer No. "a is built at
least Is inches higher than what the
profile calls for and what the contrac-
| tors figured on.
1t would be well to state at this
time that all levels are run from a
given point called a datum which NAV
| be assumed, but is usually taken from
| some we'll known fixed point, for in
stance, its height above sea level. This
datum determined when the first sur
vey was made in your town, will re-
| main fixed throughout the years to
come. This entire sewer controversy
| is evidently based on L misconception
or lack of comprehension of this fact.
You can readily see that all surveys
would be chaos unless they were made
in relation to a fixed point. Subdata,
if you will permit me to coin a phrase,
are called ''bench marks" and are To-
Gated at convenient places, usually at
intersections of streets on fire hydrant
or any other we'll fixed point. The out
fall of your sewer system was fixed at
certain elevation above this datum
and the development of system of
| mains and lateralS is carried from this
point. The contention is that this
grade was raised which is ma nfeStiY
impossible, for the reason that outfall
of No. "a was cnnnected with No IA
some years ago. However. there was
an error made in station 90" By
consulting profile of old District No.
IA and following line through center
of manhole it is very plain to see that
the railroad dump is the point imme-
diately adjacent thereto. 1t is evident
that your craftsmen scaled back to

showing this stub somewhat out of
place. BY consulting the profile you
will note that the cut under the tracks

cut as is shown by the field notes
This means that this point is the same
today as 1t was when the original sur
vey was made and that this point is
therefore fixed. 1 transferred the
angle at which stub intersects old NO

driven an iron bolt about Is feet from
the center of the manhole and about
Z feet west of the tracks to mark same
The elevation of the surface of the
ground at this point is 14-O5. Whlcn Is

Santa Fe tracks, as stated, checks with
the profile within 0.O7. 1t is therefore
impossible that grade could nave Deen
raised IS inches at stub and made up
that a uniform fall or rather raise
from stub of IL to the 100 feet was
maintained to the tracks. Bearing IN

it would have meant a fiattening OF
the grade 10 to the 100 feet. Inc
profile shows a grade of is to the 100
feet maintained from the said 1lxed
point to the outlet; field notes snow
that sewer was laid at a grade of ~

statement therefore that grade was

illustrates the above in plain figures:

Analysis of the above means that the

O624 less than the average cut taken
from profile.

mo. 2 1t is claimed that the ring
As inch brick sewer under the Mis-
souri, Pacific. and Atchison, Topeka &
Santa F'e railway tracks is only 81 feet
long, while the city engineer allowed
for the construction of 106 feet Cor

feet past the manhole at the alley pc
tween Tyler and Polk streets, running
west on Huntington avenue, that the
city engineer came and ordered
foot raise in the plan of the sewer
making a discrepancy between the pro-
file and the sewer as actually con-
structed of from to 6 feet or more
1T is also claimed that this raise In
the grade compelled change in the
plan of the sewer so as to change the
fiow of the water in the sewer from
south TO north, so as to connect sewer
No "a with sewer No. IA instead or
with sewer No. "a as originally planned.
