NEW WATERPLAN
FOR D. c. DEVISED
Supt. Phillips Proposes
Greater Supply at Saving
of Millions.
SYSTEM IS DESCRIBED
SYSTEM IS DESCRIBED

Danger of a water famine in Wash
ington today appeared likely to be
eliminated in the announcement OF a
plan devised by Asa e. Phillips. Dis
trict superintendent Of sewers under
which. it is claimed, the Capitals wa
ter supply can be adequately increas-
ed at saving in cost Of millions OF
dollars over all previous estimates and
in time required for construction Of
approximately six years.
The Phillips report, made after a
two-month Investigation, and in his
capacity as citizen and engineer
rather than a District official. was
submitted to Engineer Commissioner
Kutz today.
while 1t is not an official document,
steps thus far taken looking toward
| increasing the. water supply OF the
District, The District appropriation
bill which died with the last Con-
eross carried a rider authorizing an
| Investigation to determine the pest
45-Million-dallon Increase Seen.
According to the plan submitted by
Mr.. Phillips. which is worked out in
great detail, the capacity of the water
system can be increased to 120.000.000
gallons a day, as compared with the
present estimated safe daily capacity
Of the conduit of 100000 gallons. at
| a cost Of not more than 100000. The
time required for the work is placed
| at six months
| To increase the supply in accord
ance with plans heretofore submitted
| would cost not less than $12,O0O,OOO,
on the basis of present prices, Mr..
Phillips estimates, while the time re-
quired for doing the work probably
would be seven years.
| Former plans have contemplated
construction of an additional conduit.
Mr.. Phillips breaks away from this
line of figuring and endeavors to show
that the results desired can be ac-
complished as satisfactorily by an
other method, and far more economi-
cally.
Phillips Plan Outlined.
In brief. his proposal is for the
maintenance of a higher level in the
Dalecarlia reservoir than the present
| gravity system permits, and also the
furnishing of an additional supply of
mum consumption requirements. by
pumping from the Potomac level
| above Little Falls
] In detail, it is proposed to install a
screw pump. capable Of delivering
10000, 900 gallons per day against a
head of six feet. either in the recon
| structed upper end of the Dalecarlia
by-conduit or in a dam across the in
let end Of the reservoir. together with
suitable controlling gates, for which
diagrams are submitted.
In addition to this. it is proposed
to install a pumping station in the
vicinity of Chesapeake and Ohio
canal lock No. S, the station to be
equipped with three ten-million- gal
lon, 13O-foot-lift, turbine-driven CEN
trifugal pumps and with but one tur-
bine generator for operating the lift

about 1000 feet and the length OF

cation of this pumping station along
side the Chesapeake and Ohio canal
permits convenient delivery Of coal with
ample storage space"
Construction Costs Estimated.
For the construction of the pump
ing station and cost of installing mo-
tors Mr. Phillips estimates cost OF
SITS, 300. The next largest item OF
cost is one of 100000 for the force
| MAN. including gates and connections
while the third largest is in the esti-
mated amount of $4,000 for the lif,
station, including lift pump and oper-
| ating motor.
Other items make total estimated
cost of $508,875, but Mr.. Phillips ex.
plains that his estimates are liberal
and that the cost would almost GER
tainly fall under 100000.

ports previously made as to means OF
