to give greater force to the whole volum
Of water, this second tunnel was extende
under the city two miles or more, in south
west direction, to the junction Of Twenty
second street aud Ashland avenue. At thj
point the buildings, wells, and machinery Q
the existing pumping-works were duplicated
! It is this second pumping g-establishmen
which will be put in operation within fe,
days. The first lake tunnel was Of five fee
diameter, the second was seven fee
in diameter; but, for some reason unknown
to US, but doubtless satisfactory to tn
engineers, the present connection between
this new tunnel and the new pumping-work
is OF reduced dimensions, say five feel, ,whicl
fact, Of course, reduces the capacity Of tn
new tunnel proportionately. Both tunnel
are available at the original works, and th
supply there may be made 70, ,000, 900 o
more gallons daily, and at the new works tn
present supply will be about 10000, 900 gal
Ions; or total Of water from the lake O.
los, ,oo0,o 900 gallons Of water daily. Addi
tionnl tunnels can be constructed at any
time, the source being ine1haustib1e.
This much rel:tes only to the introduction
Of the water from the lake. At present, un
der the demand for water on occasions, as il
extreme hot weather, and the great waste BY
consumers, the remote districts of the city
are at certain hours of the day but scantily
supplied with water, and often have none.
In other districts the force is SO weak that the
water does not risa to the second floor. An
end sought by the wide separation Of the
pumping establishments was to equalize this
force more evenly, and to furnish all parts Of
the city with abundance of water and
with increased force. For this purpose
there was laid large main Of 24-
inch diameter, extending from the Water
Works at Chicago avenue through Rush,
Oak, Crosby, and Division streets two miles
and more westward to Ashland avenue, and
south on that street to Harrison street, @
distance of two miles, where it connected
new works On Twenty-second street one and
half miles south. Another main Of 24-inch
pipe was laid from the old Water Works on
Chicago avenue southwardly through Pine
and River streets to Wabash avenue, and
thence to Thirty-ffth street, n distance of
five miles. A third main Of 36 inches WAS
laid from the same starting point, which
crossed the river and extended south through
EaSalle street to Harrison street. From the
new works on Ashland avenue a 36-inch
main is laid north to Harrison street, where
it connects with the main from the north,
and also a 3G-inch main is laid on Twenty
second street extending east, through Canal
port avenue and Eighteenth street, to Wabash
avenue, connecting with the main from the
north. There is also 3G-inch main from
street running south on
Throop street and Main street to Archer ave-
nue., and thence from the latter street to
Wabash avenue at Thirty first street.
It will be seen thot these large mnins
extend like d balt around the city,
with other large mains connecting the
outer lines at various points. Since the fire
The laying Of four-inch and six-inch water
pipes has been abandoned, and those laid
since then have been s, II, and 1G-inch
pipes, fed by others If 24, %, and 36-inch
pipes In many places the smaller pipes
nave been left in the ground and furnish
dwellings, with water, while or 12-inch
pipes have been laid in the same streets, con-
aected exclusively with The fire-hydrants. At
various points through The city vast cisterns
lave been constructed ior the use Of the Fire
Department; these are supplied from the
AXE tunnel or from ths 3G-inch mains, and
ire inexhnustib1e-
On the 1st of January last there were laid
n Chicago 40 miles of water pipe, df which
miles were of 3C-inch, 13 miles of 24-inch,
1 miles Of 16-inch, 10 miles Of Pinch, 2
niles of 10-inch, II mills OF S-inch, and 155
niles of G-inch. In New York, Nov. -, 1875,
here were 255 miles Of s-inch water-pipe.
The engines at the old Water Works have |
capacity to pump daily 74,oo0,0 600 gallons
# water. These engines have been SUBJ
tantially duplicated at the new works. In
Iarch, 1876, the daily consumption Of water |
ras a, 900, 600 gallons.
When the new and The old works are both |
Il operation, each fordng water into the
anne system, the supply Of water will reach
very building in the extreme outskirts of |
be city, and it is estimated that there will |
e pressure of 30 pounds in the remotest !
in the city. And herein will be |
ne of the greatest Advantages and benefits
f the increased water service. When Chi
ago adopted the ordira nee prohibiting the
rection Of wooden Buildings, there were
,en in existence many thousands Of such
ructures in all parts Of the city. As gen.
raj thing, these buildings are small, ,-rnrely
NJ one exceeding two sories. To large
ztent, these buildings Els in districts where
1e streets have not been improved, and
ito which, in bad weather, it is often
npossibla to carry 1e FIRE apparatus.
