P. ]. Moran completed his contract
ON the City creek aquednct Saturday,
and water will be turned into the new
channel Easter Sunday at II O'Clock.
Bv completing the immense work, Mr'

terest when it is considered what the
work consists OF snd the time required
10 complete the Job, which WAS sixteen
davs ahead of the agreed date.
The work was ordered by the board
OF public works February Il, ana on

a Tribune reporter was at the scene and

Here are the more interesting hgnres
and features of the new aqueduct that
is designed TO carry the Hood waters
of CITY creek i'll safety through the
city. including a catch basin ut the
head Of the aqueduct;
Some of the Dimensions.
The aoueduct is 2000 feet IN length,
with five feet diameter inside. 1t IS
seven inches thick from center to cen
ter over top and nine inches thick at
the bottom. Reinforced with three.
eighths-inch bars twisted seven and
one half inch centers and fve-elghths
bars twisted twelve-inch centers. The
rate of grade of flow line is 3.5l7 per
cent, and there are four curves.
Approximately the following quanti-
lies were used in the construction: Con-
crete, dam, 800 cubic yards, aqueduct,
$500 cubic yards. Excavation, dam and
basin, 5000 cubic yards; aqueduct, 3oU0
cubic wards. The aquednct Is covered
with two feet of earth. The reinforce
ment consisted of $4,000 pounds of
steel.
The bids were opened February 4,
1910, and the lowest bidder, next to
Moran, in number Of days required

Catch Basin and Dam.
The most interesting feature of the
work is the catch basin and dam IN
the canyon. This consists OF the main
dam running from east TO west length
of twenty nine feet. A wing wall TO
the northeast, fifty-four feet long. and
one TO the northwest. twenty-seven feet
long, making the total length of the
dam, with wings, 40 feet. From the
northwest end rip-rap work continues
mp the canvon. From the inside of
the main wall runs twelve.inch con
crete floor for distance of nineteen
feet six inches, and at the north edge
sloping TO the ground or bed of the
canyon stream. The height of the dam
is seventeen feet. and it Is surmounted
by three-foot siX-inch coping. At the
top of the dam is threefoot opening,
with one-inch iron rods spaced eight
and one-half inches for screen, and be-
low tins screen are three rows of ten
inch cast iron pipe.
Cares for High Water.
The high water can be we'll taken
care of with all rock and gravel find.
ing its temporary lodging in this catch
basin, and at low water the basin can
be cleaned, thus preventing gravel from
finding its way into the aqueduct.
1t is certainly creditable piece of
work. Those who handled the job for
Mr.. Moran were T. B, Gawan, superin-
tendent: +. j. Householder, engineer,
and J. r. Player, general foreman. At
one time 20S men were employed.
