ARLINGTON COURT HOUSE. Va,
August 12.-Rearrangement of the water
supply system of Arlington County to
relieve the pressure on the two 8-inch
mains crossing Chain Bridge, thereby
eliminating the danger of water short
age, was announced today by County
Manager Roy S. Braden in behalf of the
County Board The changes are being
made in conjunction with the United
States engineers Office, which also will
aid by making certain improvements on
the District of Columbia side Of Chain
Bridge.
The changes, which will include con-
Struction of several new mains in the
county, will be made at a cost of ap-
proximately $4,000. while the improve
ments on the District of Columbia side
will be made at the expense of the Fed
eral Government
The District engineers. it was stated
by Braden, have ordered material to re-
place the standard fittings at the north
end of the bridge where several breaks
have occurred during the past months,
and these will be replaced with extra
ASo'y oeSCA AlteAAA6o.
Extensions in Arlington.
Extensions to be made in Arlington
County will include completion of the
20-inch main on Military road from
Algonquin Way to the Lee Highway, q
distance of 2,400 feet: construction of a
12-inch line on Donaldson road from
the Lee Highway to the 1z-inch main
on Garrison road, distane Of 3,700
feet; construction of connecting link
from the end of the present 12-inch
line on Glebe road from College lane,
near the Lee Boulevard, to the existing
line at Brookdell avenue. in Alcova
Heights. a distance of $500 feet, and
installation Of pump with a capacity
of l,100 gallons per minute at the county
reservoir at Lyonhurst.
The lines across Chain Bridge. he
points out were designed for working
pressure of ITS pounds, but are subject
to much heavier pressure, land the
United States engineers are insisting
that something be done to relieve the
situation at this point"
The new installations, for which bids
will be opened at the meeting of the
County Board on August 81, will per-
nit the War Department to furnish
water to Arlington County by gravity
by pump pressure from Dalecarlia. as
at present, and will reduce the pressure
at Chain Bridge to point where 1t
will be below that set forth In the origi-
nal design, permitting 80 per cent of
the water users in the county to be
served by gravity instead of pumping,
the county manager said.
BY making these extensions, he as
serts, the county will be able to realize
full value on the investment made last
year on the 20-inch Military road main,
which was built to connect with the
8-inch existing main in order to pre-
ent year, "and 1t has served its pur-
pose well"
Will Relieve Pressure.
The Chain Bridge line will be relieved
from the exceptionally high pressure
pumping II hours a day, which will be
entirely eliminated, and in its stead 1t
will be necessary to operate q new pump
at the county reservoir maximum OF
only three hours day, with no result
ant high pressure, in order to serve the
small portion of the county that will
not be reached by gravity flow.
Pointing to the movement now on
foot to secure construction of a new
Chain Bridge, Braden states that it has
been agreed between the county and
War Department engineers that the
changes to be made will amply care for
the supply for some time to come, and
if the new bridge should be built, new
line could be placed in a conduit In its
construction, saving the county the high
cost of constructing a 24-inch main
across the river in the vicinity of the
bridge, as would be necessary If this line
were constructed at the present time.
