Springwood Water Supply
PUMPING FROM LINDEN CREEK
ESTIMATE PREPARED.
Hon. J. C. L. Fitzpatrick, M.L.A.,
has received the following communica-
tion from the Under-Secretary Public
Works Department:-
Adverting to previous correspondence
regarding the proposed scheme of
water supply for Springwood, I have
now to inform you that a survey has
been made and an estimate prepared
for supplying Springwood with water
by pumping from Linden Creek.
The present population of Spring-
wood is computed to be about 1,200.
In view of the numerous visitors in
the summer, provision has been made
for a population of 3000. The source
of supply would be a storage reservoir
formed by the construction of a dam
in Linden Creek, at a point about 2½
miles distant, in a direct line from
Springwood Railway Station. The
area of the catchment is about 5½ sq.
miles, and the capacity of the storage
about 120 million gallons, with a max-
imum depth of water of 53ft. The dam
would be constructed of concrete curv-
ed in plan. From the storage reservoir
the water would flow in a suction main
to a pumping station a short distance
downstream of the dam. The machin-
ery would consist of suction gas en-
gines driving two sets of centrifugal
pumps. The capacity of the two when
working together would be 15.000 gall-
ons per hour. Thus with two sets
working 8 hours per day, 6 days per
week a volume of water would be sup-
plied sufficient for a population of
2,060 with 50 gallons per head per day.
Should the consumption in summer be-
come larger than this volume the de-
mand could be met by pumping for a
daily period of more than 1 shift. The
water would be pumped through a
raising main of cast iron pipes 8 inches
diameter and 1 mile long to a service
reservoir having a capacity of 200,000
gallons and constructed of reinforced
concrete 0n the high land near
Faulconbridge. From the reservoir
the water would flow in a gravitation
main to the reticulation of the town.
The service main and reticulation
will comprise the following cast-iron
pipes: 8in. diameter x 235 chains, 6in.
x 114 chains, 4in. x 190 chains, 3in. x
11 chains; total, 550 chains (nearly 7
miles).

ing Machinery, £3,500; Rising Main,
£4,500; Service Reservoir. £3000; Grav-

£47,700; Engineering and contingencies
10 per ent., £4,770; Expenditure to
date as per accountant's statement of
13/8/23 on survey for this scheme,
£182 do part expenditure on Blue
Mountains villages generally, say
£300; Interest during comtruction,
>«en ii period, about I year at 5.81 per
ecnt.,!Bny, £3;048. Total, £56,000.
Estimated Annual Cliargo:-Annual
i©payment to cover intorest and sink
ing fund on £50,000, with interest at
per cent., 0.21 por cont
Por annum, £3,478; Konowal
fund to provide for replacing items
J, and 7, with intercut nt 4 tier
Fiji'.' £a\°00 f 2,4 Por C(-'ut- 1^' nuuum,
£144; Administration charges, £200
Engine Drivers' wages, including pro-
vision for annual leave, £350; Wages
of turncock, half time at £5 per week,
£130; Repairs and stores, £100; Fuel
for pumping 22,000,000 gals., 84 cord
of wood at 25/-, £105. Total £4,597.
Cost of water per 1,000 gallons for
present requirements, 4/1.
A general plan of the works and a
plan of the reticulation, together with
the information contained in this letter
has been forwarded for the considerat-
ion of the Blue Mountain Shire
Council.
