The Morris County chronicle. [volume] (Morristown, N.J.) 1877-1915, 1907-10-01

This estimate is based on vitrifieC
pipe, except for the stretch covered by
the siphOn, and the 100 feet across the
MorriStoWn and Erie Railroad right OF
way, in order that it may be compar.
able with previous estimates made
over this route or similar routes.
There is about 900 feet across the
Whitnall Tract and adjacent to the
Morristown and Erie Railroad that we
could not advise laying as vitrified. 1t
is laid over private ways and through
woods and exposed to the roots OF
trees, which as is well known, will find
access to sewer through the most
minute hole or crevice.
To-Day vitriiedpipe with joints ever
so carefully made would we believe be
short sighted policy of economy. We
would recommend iron pipe or con-
crete, preferable the former. This
would add So, 120.G0.
Further, we have made no estimate
for lumber left in the trenches, nor for
pumping. 1t is fact easily deter
mined that the line for its entire dis
tance'will be laid below ground water,
ground water that will stand over the
pipes from six to ieight feet, and if Wit
rified pipe is laid through here, we
certainly recommend that the joints
be made in the most approved manner.
LII joints are used such as are being
used under the contract of Antonio
Costa for Pipe Sewers at the rate of 80
cents per joint, ft-would add $4,000 to
the estimate ofcost. AS before stated,
no allowance has been made for lum-
Der left in trench, nor for pumping In
heavy cutting the lumber item is con-
siderable, and for this trunk line, con-
sidering the nature of the soil, this
item will be considerable.
Summing up the cost of the trunk line
then we have:
Cost of gravity line, $50, 1896 90
Substitution of cast iron pipe 900
feet. a,l2O 90
Caskets for joints, 400 90
Lumber left in place, foundations,
drainage and incidentals, 5000 90
So, 600 90
To this estimate should be added the.
cost of the private ways, legal expenses and
engineering. For the siphon line 81. S6l 90
less,
DISPOSAL PLANT.
A disposal plant was located at the Hid
farm as shown on the accompanying map.
Four test nits were sunk to determine the
character of the bottom, and also to find if
any sand present could De saved to use in
the beds.
1t was the intention to dig the pits to a
depth OF 3 feet to reach subgrade On the
plant, but this was Impossible on account of
the immensesamOunt of water encountered
In every pit the ground water rose to prac-
tically the surface of the ground.
The pits showed an excellent quality of
.ts&.a ftf.eN. Al
OVERLAND with about feet of ciayey loan,
and underlaid with clay. This clay was
penetrated to depth oil about one foot.
This clay would make an excellent tOunda-,
ton for the contact beds and septic tanks,
but is not at proper elevation for the
filters.
Y The location for the disposal plant shown
requires $500 cubic yards of excavation for
the present needed plant, and 26,SC9 cubic
yards for the duplicate, which is considera
bly, more than half that required on the
WLitnall tract. Practically ali OF this would
be wasted, as the plant lie almost entirely in
e5 cavati0n.
An examination of the sites leads us TO
the following conclusions;
III No saving could be made in excaya-
ton by building plant on this site over the
one on the Whitnall tract because the TO-
Biography of the Hid farm is not so suitable
for building a disposal plant The unit
price or ~ cts. per yard for excavation on
the Whitnall tract would be greatly exceeded
on the Hid farm.
i2) The character of the soil on the Hid
farm is not so suitable for the building or
maintaining of disposal plant The test
pits showed water standing at the surface of
the ground in September, and further the
quality Of the grass growing on the site
being the kind that grows on alternately wet
and dry ground, some of the vegetation being
bull PUSHES, which grow only in swampy
ground.
,s) That the sand on the Hid farm
would have to be brought from the Hanoi
yer avenue bank, as none Is To be found
available on the Hid farm in sufficient
quantities. This would cost on an average
of 80 cts per yard more. or for the O,CjO
yards s., 0v0Oc. An outfall pipe to the
river would be required here, which would
be about $4,000 in excess Of that on the
Whitnall tract.
1t is safe TO place the figure for build ng
the disposal plant on the Hid farm at
81, .OO more.than on the Whitnall tract.
Altogether we would place the cost of
building on the Hid farm over the building
on the Whitnall tract at about the following:-
Gravity line, $46,2tj CO
Siphon line, 43 345. 90
Exclusive Of real estate, rights of way, etc.
We believe these estimates to be eonserva-
tive, and the lines chosen and the site chosen
on tue Hid farm to be the best and most
feasible.
10 regard to these estimates, we wish to
call your attention to the fact that our esti-
mates for the pipe sewers, the pipe aud the
disposal plant on the Whttnall tract exec eded
