PLANS SUBMITTED
FOR WATER SUPPLY
Specifications Are Sent to
Hurley and Gen. Brown
for Approval.

Washingtons water supply will be
increased by 345 900 900 gallons and the
National Capital will have sufficient
water en- hand for five days, instead OF
only day and half as at present. when
plans now before Secretary Hurley and
Maj Gen. Lytle Brown. chief of Army
Engineers, for approval, are executed.
Specifications for the rev work. for
which Congress has made available
$150,O00 In the District appropriation
act, were drawn up in the Office Of Maj.
joseph D. Arthur. ir.. district engineer
for the War Department for the Wash
ington area AS soon as the plans
receive the approval Of the War Depart
ment heads bids will be called for the
construction of a dam at the west end
Of the Dalecarlia Reservoir.
Pump manufacturers will be asked to
design four special pumps for handling
the increased capacity. and when it is
decided what type is best suited for the
Dalecarlia filtration plant located on
Conduit road near the District line.
arrangements will be made to construct
q new building to house the new pumps.
Work to Take a Year.
E. D. Hardy, superintendent of the
Dalecarlia and Mcmillan filtration
plants, said today that this work will
take about a year, about six months
being needed for the design and build
ing OF the special pumps alone. A To-
foot dam is to be constructed. Ct the
rock fill type. at the west end of the
Dalecarlia Reservoir making the main
part Of the reservoir 7 feet higher than
the other part. This is calculated to in
crease the capacity Of the conduits.
enabling the water to flow mere quickly
to Washington through the great tubes
from Great Falls. Mr.. Hardy explained
that this will make for lot more water
and much better operating conditions.
Mai. Arthur explained that the pro-
posed new booster pump at the Dale
carlia Reservoir Inlet will provide for
construction of pumping plant at the
outlets of both the old and the new
conduits. where they discharge into the
Dalecarlia Reservoir. Two purposes will
be served by the new construction-it
will draw down the water in both con-
duitS, increasing the slope and greatly
increasing the capacities Of the con-
duits and raise the water level in the
Dalecarlia Reservoir, the district en-
gineer said
The generation of more electric power
Tor the operation OF the Dalecarna nigh
service pumping station Will be made
possible, the major asserted. decreaS-
ing the amount OF electric power to be
purchased. Maj. Arthur estimates that
a net saving of about $4,000 per an
mum will be effected, after deducting
per cent interest and per cent for
depreciation.
Five Days Supply.
The water not used for drinking pur-
poses or other use in the city is utilized
by the District engineer to generate
power which is used for pumping the
purified water.
Maj. Arthur told Congress that it was
a matter Of safety for the City of Wash
ington that appropriation of the $780,
0Oc should not be deferred for a year.
The amount OF water stored in the
reservoirs throughout the city, he said,
will be increased by the new construc-
ton by 45,000,000 gallons. At present,
should something happen to one Of the
conduits. the ma ior asserted, there is
water enough only for a day and a
half's consumption. The new improve
ment will increase this capacity to five
days supply.
There is small likelihood Of water
famine here, however, Maj. Arthur
says. as even during the height Of the
drought, two years ago, the city's sup
ply vas not ieopardized
