To further improve the efficiency of the existing water supply system, during
this year (1941) the smaller street water-mains within the Cessnock Division
were cleaned and cement-lined. This internal cement-lining of water-mains
was done 'in situ' by a contractor. Cement Linings Pty. Ltd. This problem
was quite lengthy and it was just over ten (10) year before it was completed.
Cement lining of the reticulation pipes not only improved the suppl¥, but also
the quantity of water distributed.

Like the Cessnock Sewerage Scheme, a proposal to introduce a sewerage
scheme for Kurri and Weston areas received quite some consideration by the H.D.W.B.
before it actually came to fruition. The implementation of this type of scheme
was as always, dependant on the availability of funds. The Board with its wide
area cover was at all times committed to the amplication of exisiting water
supply and sewerage schemes. During 1939 it was decided to proceed with the
sewerage scheme for Kurri and Weston. A large area of land, 178 acres, being
part of portion 8, 9 & 538, Parish of Heddon was acquired as a treatment works area.

The Department of Public Works was the construction Authority and the
major portion of the scheme was transferred to the H.D.W.B. on 24th May, 1940.
This scheme in the main involved gravitational sewer mains with three strategically
placed pumping stations. This scheme was a biological filter system, with the
chlorinated effulent finally being discharged into Fishery Creek.

Kurri No. 1 Sewerage Pumping Station is located just off Mitchell Street,
Kurri near the South Maitland Railways track. Tbe pumps at .this pumpin_g station
like those at the other two Kurri Pumping Stations were supplied by J.T. Jay on
the 6th Dec~ber~ 1940 to meet the Board's contract No. 422. The two pumps, as
Units 1 and 2, are both seven-inches (7") "J.&S." vertical centrifugal sewer pumps.
Each pump works at 960 revolutions per minute with a seven-inch (7") suction section.
The pumps are driven by a 40 H.P. Crompton Parkinson electric motor (Note: 415
volts, 3 phase, 50 cycles). The pumps work at 75- gallons per minute to lift
a seventy feet (70') level. These two pumps cost £1180.0.0 ($2360.00).

Kurri No. 2 Sewerage Pumping Station is situated just off Cantwell Street,

Kurri. It too has two Units, No. 1 & 2; each unit pump is a six-inch (6 11
),

single stage, centrifugal sewer pump. Each pump works at 950 revolutions per

minute with a six-inch (6 11 ) suction and a six-inch (6 11 ) drive sections 550 gallons

per minute to lift a forty-two (42') feet level. The pumps are driven by a 12~ H.P.

electric motor, (Note: 415 Volts, 3 phase, 50 cycles). The brand of the motor

is not known, but it was a 'protected S.R. induction' type. The two units cost

£77 1. 10. 0 ($154 3. 00 ) .
