What Lieutenant UoNie Thinks of the Plan
for Increasing the supply.
Lieutenant Hoxic has transmitted to Engi.
neer Commissioner Twining the following
statement in regard to the supply Of water on
Capitol Hill:
! have considered the plan for increasing the
supply to Capitol Hill by shutting off the 3G.inch
main from the 30.inch and 12.inCh mains, and re.
serving the former for the high grounds and the
latter for the low grounds This was TO be effected
by closing the 30 inch stop ut the intersection Of
New Jersey avenue aud Massachusetts, avenue, and
the 2O.iuch stop at the intersection Of Delaware
avenue and street, and laying a Pinch main on
First street west from Massachusetts, avenue to
stop at New Jersey avenue and Massachusetts ave
nue.. and of the 2linch stop at New Jersey
avenue and street northwest completes
the isolation Of the S0inch from the S6.inch
main. The effect is to shut Off the sup.
ply TO the Island and to raise the head Of water on
Capitol Hill about seven feet. 1t also cuts off the
supply which reinforces the Pinch maiu ut Penn.
svlvaniN avenue from the 2O.inch. leading to the
Island. This Is all the increase OF head that can
be given on Capitol Hill by the separation Of the Sc
inch from the u and 20.inch mains, and turning
the supply of the former to the northwest section
Of the city and to Capitol Hill. The flow to the
Island through the 3Olnch main down New Jersey
avenue being cut of, as well as the additional sup
ply TO the j. inch main at Pennsylvania avenue
and First street northwest these quantities must
be supplied by other connections between the 30.
Inch min on X street, the Pennsylvania avenue
main and the Island. Assuming the quantity
I
Of head in. delivering it through the 3o'imcn
main on New Jersey avenue, past the nearly
closed stop on Is street TO the 2O-inch Island main,
Is about rs feet, and the elevation at which IL is de-
livered is none too high. TO restore this quantity
of water to the Island and the Pennsylvania avenue
main with only the same loss Of head will require
two l2inch mains laid upon the liuo of First street
west II only one main he laid, the @0nch stop
must lie left partly open, with proportional di-
minu,iOn of the seven ca feet additional head ON
Capitol llill Seven feet additional head on Capitol
| Hin will be Of little practical benefit If 2Onch
main should prove inadequate TO the supply of the
low grounds 1t would have to be further reinforced
| from the SG-inch man with q further re-
| ducion of the head on Capitol Hill. If not
ut once the case, this would happen sooner
| or later First street west is not the proper
! line for either one or two circulating mains. The
line is too near the parallel line of New jersey ave-
nue. which is the 3O-inch main. 10 accom-
| rish the better circulation of the supply of the
80 inch street main, three II inch mains are nee
! cssaIy to be laid nj proper intervals from the
| street main TO the Pennsylvania avenue main and
the lSlaud-say on Fourth street Eleventh street and
Fifteenth street. The aggregate length of pipe will
! be - and the cost about 81 900 These maint
viii form part Of the permanent distribution sys
TEN and should be put down, They will fail L
give the desired relief to the high grounds bccaus,
that relief can ONLY be given by large increase OF
| the water supply by a universal reduction of tho
| consumption OF water throughout the city or by
pumping the entire supply for the high grounds.
