believe these estimates were made with the
same painstaking care.
These estimates as stated are made to Won
for our information, and to furnish a basis
for comparison of cost of the two sites in
question. 1t Is hoped that if change Of
site is made the legal phases of the question
will allow some chances to be made in the
design of the disposa al plant, because of the
change of location. while the plant can be
built ON the Hid Farm, the sewage will be
considerably older, and must necessarily re-.
ceive somewhat different treatment. 1t is
well known among engineers converse MT
with the design of sewage disposal plants
that the age of the sewage is an important
factor in its treatment.
Our attention has been called to the fact
that it has been suggested by critics that the
"a inch outfall from Ridgedale avenue TO the
Whitnall Tract be laid with vitrited pipe in
stead of iron, as proposed In the contract
with Antonio Costa. 1t seems hardlyneces.
sary to remind you that the outfall sewer is
laid through wood lot, and the sewer will
always be endangered by the roots of trees,
unless concrete or iron pipe sewer is laid
SO as to eliminate joints and crevices through
which the 70 It's might grow. 1t would be
cheaper in the end } lay an iron pipe or one
that roots will not penetrate, than be subject
to the expense and annoyance OF the con-
tinual repairs to vitrifed pipe.
This is the trunk hat carries the sewage of
the entire Town and stoppage in this trunk
would be of considerable moment and ie-
quire by-passing the raw sewage into the
Whippany River.
We might remind you also that the City
Engineer for the Board of Aldermen went
over the plans of this outfall and as he re-
commended its increase from 20 inches to "a
inches, and further recommended the use of
iron pipe in Ridgedale avenue to Albeit ave-
nue., where we had called for clay pipe, so
we are led to the opinion that he is one local
engineer who believes the reasons for laying
an iron pipe along the raceway are adequate.
An error in the criticism of this iron pipe
affects the results somewhat. The engineer
who makes the criticism states that the con-
tract calls for the use of extra heavy iron
pipe. On the other hand the iron pipe called
for by the contract, IS standard weight pipe,
a much lighter weight than extra heavy.
You should perhaps know that the map of
the Hid Farm presented to you by the par
ties holding an option on the same is mis-
leading, ine smuch as it shows the upper
portion Of the Hid Farm to be about i've
feet lower than the facts warrant
This will be apparent to you by COM
pa. son of the map mentioned and the one
furnished you by us. This error in no way
effects the disposal plant as laid down by us
ON the Hid Farm. as we have used our own
information in preparing our plans and costs.
In conclusion we wish to say that we do
not SUBSCRIBE TO tne opinion Jhat the 1liu
Farm is more suitable, cheaper and better
than the Whiinail Tract. We do not believe
it has been proven so.
We believe that to build on the Hid Farm
would cost from forty to fifty thousand dol
lars more than on the Whitnall Tract, as
shown by our estimates. We believe with
Col. Fuller of the State Sewerage Commits
sion that neither site would prove objection
able if the plant could>be built over night.
However. the questions relating TO effect
on real estateva lues bv either location, and
the sentimental reasons against either loca-
ton. are matters for your Honorable body to
consider.
To aid you in this consideration, and to
furnish you basis for comparison of costs,
the above is
