WATER COSTS

Betts-is given below;
Investigation was made on jan
uary 14th, 1924, at which time Mr.,
Edward ]. Moonan, Mayor of Lam
bertvoille, and various representa-
tives of the water company were in
terviewed. 1t appears that the To-
cality known as Cottage Hill is at
approximately the same general ele
vation as the filter basins which
supply water by gravity to the entire
city. A large number of houses in
this area are located at a higher
elevation than the filter basins.
The Lambertville Water Works
operates entirely by gravity. No
pumps are employed anywhere in
the entire system. The water is
impounded in the collecting reservoir
from which it flows to the filter
basin and thence to the distribution
system. The greater portion of the
city is approximately at elevation
! so, while the elevation of the sec
ton to be supplied averages $50.
/ Under most favorable conditions,
water from the present system
would just reach to the level of
point located on Studdiford Street,
between Douglass and Lincoln
Street in the Cottage Hill section.
During the day when the factories
are operating and at times of fire
when large quantities of water are
required in the city proper there
would be no water in this section.
1t is quite evident, therefore, that in
order to render adequate and suffic-
lent supply of water from the pres
ent public supply to the Cottage
Hill section it would be necessary to
install booster system.
"There are approximately so
houses on Cottage Hill, as compared
with approximately GOO consumers in
the city proper. If all of the so
houses in the Cottage Hill district
agree to take water from the public
supply and the city agrees to pay
for ten hydrants the company would
obtain additional revenue approx
mating S700 per year. To obtain
this revenue it would however be
necessary to install 1900 of 6" cast
iron main from the present main on
j Quarry street to reach the Cottage
Hill section and approximately 5000
] fl. of distribution main along Swan
street, Lincoln avenue, Douglass
street. Highland avenue, Studdiford
street, Stryker street, Boozer street
and Cottage street. making the total
of approximately $500 fet of main.
! The soil in this location contains a
large proportion of shale and trap
rock, which materially increases the
cost Of installing cast iron mains
/ Assuming the cost of installing 6"
cast iron pipe at 50 per foot, which
/ is a very low estimate for the nature
Iof the ground, the total cost of the
main would amount to S29, 400 In
sary to install pumping station
and overhead storage tank of not
less than $4,000 gallons capacity on
Cottage Hill costing at least $4,000.
There should also be added about
1000 more for the installation of so
service connections main to curb
and another 1000 for the installa-
ton of ten fire hydrants, bringing
the total cost to the water company
of extending service to the Cottage
Hill district to at least S46,400. The
new pumping station would not be
of any service to any other portion
Of the city because the difference in
elevation between the source of sup
ply and the present distribution sys-
tenn is sufficient to give adequate
pressure at all times.
"At present real estate develop
ment in the Cottage Hill section
is practically at standstill. Con-
lsequently the water company could
not reasonably be compelled to
make the expenditure of such
large sum of money without cost to
or guarantee by the city or by the
residents benefited thereby.
"The following table shows the
fixed and operating charges that
would be incurred in extending SER
vice to the Cottage Hill district:
Operating charges Based on
consumption of $4,000 gallons per
year per consumer. Power to pump
2,500,000 gallons of water at &c. per
thousand gallons, 500; operating
labor (part time, automatic station)
S400-S500 Maintenance and water
supply expense per consumer S4.10;
general and administration expense
per consumer $2.35; total $6.45; for
80 consumers, S325; total operating
charges per annum, 1925. (*1922 an
nual report.)
"Fixed Charges On expenditure
of saga useful for Cottage Hill
section only, z p. c. interest, 2 pc.
depreciation, l pc. taxes, total of
10 p. c. per annum, $4,640.
Fixed Charges-On remainder of
plant valued at $4,000, 10 p. c. per
annum, $1,000; allocated to Cottage
Hill $50 divided by 700, multiplied
by $1,000, or $500; total fixed
charges per annum, S5,14O; total
charges per annum, $5,965. s5,965
corresponds to gross return of 10
lp. c. on an expenditure Of $46,400.
at is RECOMMENDED that the
Lambertville Water Company take
the necessary steps to give domestic
and fire service to the Cottage Hill
lsection of the City of LambertvilIe,
