these reasons-That it is great advantage to
have all the steam power concentrated at one
point; that the works are provided with an
ample forobay 20 supply double the number of
engines now drawing from 1t; that coal can
here be delivered at great advantage; that
from this point the highest of our reservoirs
can be easily reached by mains of moderate
length; and, finally, that auxiliary power can
here be made available sooner than at Fair
mount.
1t is proposed to take out Engine No. 9, which,
with its boilers, has been In almost constant
use for over twenty-four years, and erect In its
place side-wheel Cornish engine, and as soon
thereafter as possible to remove Engine No. 3,
and replace it by one of much increased power
and improved construction; this will fill the old
engine-house, and will probably he sufficient for
several years. 1t is then proposed to erect
new engine and boiler house on the western side
of the torebay, between the present coal shutes
and the river, and place therein engines OF ade-
qlate power to pump through stand-ptpe to be
placed upon the rocky bluff behind the proposed
house, into any new reservoir which may be
erected within n reasonable distance, while, at
the Delaware works, new engine is positively
a necessity.
Mr. Graf states that the water power at Fair
mount will be greatly improved by increasing
the height of the dam two feet, for then the
wheels could be run with the expenditure of
about % per cent. less water than at present.
Inasmuch as, by the raising of the dam the
Schuyllill Navigation Company would be bene-
fitted he suggests that they share in the expense.
The Twentieth and Twenty-eighth wards call
loudly for better supply than can now be fur
nished them. To remedy this, the Chief Engi-
neer suggests five eXpedients:-To continue the
twenty-inch main now laid from the RoXborough
reservoir to Ridge avenue and jefferson street.
which may be considered as the centre of distri-
button of the ward; tolay mains from the reservoir
now building near Georges HILL across the
Grard avenue bridge; to construct a reservoir
west of the Schuylliill for the special supply of
at1
construct new reservoir at Strawberry Man
sion, and to use engines to pump into stand
pipes, taking their supply from present reser-
yoirs. The Twenty-eighth ward covers 300,
and the Twentieth, 1l14 square acres. MIR.
Graft estimates that the Twentieth ward will re-
quire 4,500,000 gallons per day, assuming its
population now to be 60,000, and the Twenty
eighth ward about 235,000 gallons, taking its
population ut 1000. In view, however, of the
rapid increase of these wards, the department
should calculate for a supply of 100000 gal
Ions per day
The Chief Engineer goes into quite discus
sion as to the best of the eXpedients he has sug
gested for the relief of these wards, and con-
cludes that the one proposing the erection of a
new reservoir on Strawberry Mansion property,
Of about 10000, 600 gallons capacity, is the
soundest The site is upon the grounds of the
city, and the reservoir could readily be supplied
from the Schuylliill works by main 1900 feet
in length. As to the balance of the city, it is
proposed to erect q reservoir capable of storing
635, ,704, 200 gallons upon the eastern park, high
and adequate enough to supply all but the Twen-
tieth, Twenty-frst, Twenty-second, and Twenty
eighth wards, these to be supplied by the pre-
sent system and the new one mentioned above.
If the reservoirs described are built, the entire
storage capacity in them and the old ones. eX
cepting RoXborough and Germantown, will be
S21, ,603,311 gallons, equal to "a days supply, or
22 days longer than ut present.
The Engineer ends his report with an approxi-
mate estimate for all the works described in it,
OF which the following is an epitome:-Reser-
voir on Strawberry Mansion, capacity, 80, 120 900
gallons, for the Fifteenth, Twentieth, and
Twenty-eighth wards $4,000; reservoir on
East Park, capacity, 635, ,99s, 200 gallons,
81, 1914. 407; reservoir near Delaware works, ca
pacity, 13,39S 475 gallons, $160000; to enlarge
Belmont reservoir, $4,000 Total for all reser-
vors 81, ,779, 007.
Ascending and descending mains to said reser-
voirs. of all kinds Ss76S, 700; two new Cornish
engines at Schuyllill works, $4,000; boilers,
etc, $74,S50; new turbine at Fairmount,
$145,0O0; rebuilding dam, $215,0O0, making a
complete total for the projected improvements
Of 81 100 o51.
