Anacostia Reclamation Work Going For
ward, Engineer Chief Says-Urges Re-
moval of Old Aqueduct Bridge.

Steady progress in the execution of
the project instituted in 1923 for
doubling the water supply of the Dis
trict of Columbia, at total author.
lied cost of $9,169 900, is shown in the
annual report of Maj. Gen. Edgar Jad.
win. chief of engineers, submitted to
Congress today. Though no official
statement is made as to the date of
completion, the engineers In charge o.
the work privately have expressed the
hope and belief that the auxiliary sys-
tenn will be practically completed and
ready for operation during the next
fiscal year, and possibly as early as
January l, 1928, within the limits Of
the original estimate Of cost.
Gen. Jadwin outlines the status Of
waterways development In this sec-
ton. tells Of the progress of the rec
| lamation work on the Anacostia Flats
Aqueduct Bridge.
During the past fiscal year 81 ,934,.
ITO was expended in the construction
of the filtration plant and pumping
stations at Dalecarlia, two high.ser-
vice reservoirs, high.service tunnels
and pipe lines, substructures, etc.
Gen. Jadwin saws that the sum of
$127,600 can profitably be- expended in
completing and testing the work dur.
ing the fiscal year ending June 80,
1928. He saws that all the major fea-
lures of the project are practically
completed, and that the remaining
items, with the exception of the nee
essary repair of the old tunnel to the
Mcmillan filtration plant and tests of
various sections OF the system. will be
completed during the next fiscal year
The additional supply water works, he
says, are to be used for purifying and
supplying water to all the high areas
within the District of Columbia where
pumping Is required to lift the water.
Publication Satisfactory.
Regarding the existing supply sys.
tenn, Gen. Jadwin says that the
publication of the water during the
past fiscal year was very satisfactory.
/ the average turbility having been re.
terial content from 4,I65 to per
cubic centimeter. The average con.
sumption was 69.2S million gallons
per day. making the average per
capita consumption 140 gallons per
day. Twenty-Five thousand four hun.
dred and f1fty-nine pounds Of liquid
chlorine, at the rate of OF per million
gallons, were applied for sterilizatio
to the water leaving the filtered water
reservoir for 2S7 days during the
year.
The operation and maintenance of
the existing system during the past
year cost $197,210 and Gen. Jadwin
says that $202.210 can profitably be
expended for that purpose during the
coming fiscal year. An accompanying
table shows the high daily consump.
ton Of water in the various Govern
ment buildings in this city. The Navy
Yard heads the list with a daily con.
sumption Of 1,35s.S05 gallons, fol.
lowed in order by the Bureau Of En-
craving and Printing at 935,520 gal.
Ions, the State, War and Navy Build
ing at 6S7,227 gallons, the Agricul.
tural Department at 466,7S5 gallons,
the Geological Park at 431,S76 gal
Ions, the Government Printing Office
at 3S7,9SS gallons. the Post Office at
372,0S6 gallons, the Treasury Depart
ment at 232,017 gallons, parks and
reservations at 227,576 gallons, and
smaller quantities for all the other
Government buildings.
Gen. Jadwin makes a strong plea
for additional funds for the continued
improvement of the channels of the
Potomac River between this city and
the mouth of the river, a distance of
10S miles, and also for the channels
of the river opposite this city. Shoal.
ing has recurred at Kettle Bottom,
Maryland Point. Smith Point, Malta
woman, Marshall Hall and Naval
Magazine and threatens to interfere
with navigation. An allotment Of
100000 has been reserved from the
1926 appropriation, Gen. Jadwin says,
and will be expended in maintenance
dredging. That sum will be exhausted
by June 80 next and the Chief of En-
gineers says that $156,000 can be
profitably expended during the fiscal
year 1928 in continuing the work. The
existing project provides for dredg-
ing a channel "a feet deep at mean
low water, and 200 feet wide, from
this city to the mouth of the river.
Commerce for the calendar year 1925
is reported as 2,439.36 short tons,
valued at S54 ,043 800, the principal
items in order of tonnage being sand
and gravel, petroleum and it's
products, forest products, general mer-
chandise, fertilizers and bituminous
