DISTRICT WATER SYSTEM
Gen. Craigh!ll's R port Treats Ex-
clus!veiy of 1t.
Detail of the Years improvements
and the Scheme Projected
for Future Work.

The water supply OF Washington is the
subject of an interesting report by Geh.
Craighill, chief OF engineers.
The improvements in the supply system
for the past year receive Considerable
share of the attention OF Gen. Craiehill.
These improvements embrace the change
of the Dal.carnial reservoir from the re-
serve of the service supply, which IN itself
doubled the service water, and the opera
tions for cleaning the conduit and It's
branches. The latter were provided for in
the act of March 2 1895, and at such
times when the conduit could be empticd
without interfering with the water sup
ply, 1t was carried forward and 63,O5l.22
linear feet of conduit Were cleaned the
cracks mended with cement cortar, and
S.9i6 cubic yards OF sedlmentary uepuist
removed.
The effect OF these improvements was
shown in the limited fluctuation OF the
water level in the distributing reservoir.
Where in the past, the range OF level had
been as great as A. L feet, az in s94-5, the
eXtrcIne IN 1885 was but | g feet. The
obstruction in the conduit varied from
| l2-S To 16.4 per cent Of the cross section,
and its removal has increased the useful
hess of the service pipes to that extent.
The average daily consumption OF water
| for the past year was "A, 1854 gallons,
| an nayerage of 73 gallons to each consumer,
| US gwen by the water department report.
The CHIEF engineers report covers III
detail the work done in raising the heish;
| OF the Great Falls dam. The total length
| of the dam is 2.e11 feet and the height
| added L. 20 feet AT the close of the
| fiscal year the dam had been raised 10 the
| full height for distance of ,39i IS fectaud
| rip-rap work had been done for total
| distance OF ,s25.S.
| Upon the subject Of the L ydcckcr tunnel,
| for the testing Of which $4,000 was
| appropriated by the act approved March
=, 1895, Gen. CraiGhill says:
Upon recommendation OF the chief of
engineers, approved by the Secretary Of
| War, an epert commission was appointed
| TO meet i'll Washington in December. 1888.
| to report upon the feasibility of completing
| the tunnel conduit. After a careful study
| of the subject and a thorough inspection Of
| the tunnel conduit, and the works connect
| ed therew with. the commission submitted
| their report, which concluded with the
| statement that it is our unanimous judg
| ment that IT is feasible to Inplctc the
tunnel conduit. with its appurtcnanccs,
| ready for service, for the sum OF SS9T ,S31,
| as stated III our estimate, and We believe
| that such completion will net te imprac-
| ucable or too expensive. inasmuch as We
| know of no more economical method for
| bringing increased water supply from the
| reservoir i'll Georgetown to Washington by
| pipes or otherwise.
"As an essential part of this system. it
is necessary TO complete the new reservoir
near Howard University at an estimated
additional cost of $l9S,O13.3O.
..In view of what precedes, therefore
| recommend that the sum of $500, coo be
made Immediately available for resuminG
the work of completing the tunnel conduit
| betw cen the distributing reservoir and the
new reservoir, near Howard University,
and for the other works connected there
| with including the latter reservoir.
