In May 1968 Alcan Australia Ltd in the construction of its smelter works
at Hart Road, Loxford on the Wentworth Swamps adjacent to Kurri and Weston
introducedits own sewerage link. The sewer wastes were pumped into the Weston-
Kurri Gravitational pipe reticulation.

As part of the construction of the Kurri "Yawarra" Boys Home on
Government Road, Loxford, water from the H.D.W.B. mains at Kurri connected.
Also a small sewerage scheme was designed in this State Government Development.
This sewerage scheme required a pumping station for it to be placed into the
Kurri Sewerage gravitational reticulation pipes: . On 7th May,1968 on authority
of Contract No. 227 at a price of nine hundred ($900.00) dollars, suppliers
Watermove Equipment Co. provided to the project contractors two (2) electrically
driven submersible sewerage pumps. These submersible pumps were single port
"Model C~P.A.-100" type. They operated at 1450 revolutions per minute and had
a three and a quarter inch 3~" suction and a four-inch (4") drive to produce
sixty-four (64) feet lift. The pumps were driven by two "Hagglund" submersible
squirrel-caged electric motors. (415 volts, 3 phase, 50 cycles) which also
operated at 1450 revolutions per minute.

Yet still another village "Mulbring" was connected to the H.D.W.B.
mains on 2nd September, 1970. The reticulated water supply for the Mulbring
area consisted of a pumping station at Pelaw Main, a high level water tank at
Mulbring, 9.25 miles of six (6 11 ) inch water mains and four-inch (4") cement
lined cast-iron village-reticulation water-mains. The Mulbring elevated tank is
situated on Lot 14, Portion 17, Parish of Mulbring. The land was acquired by
purchase from J.F. Forster and finally settled on 15th January, 1975. The
tank is of circular design; twenty-five (25') feet in diameter; built of steel
construction. The depth is seventeen and one third (17.1/3') feet when full
and this level is then 275 feet above sea level. Mr. J. Thompson was the Water
Board's construction engineer.

In September 1970 a temporary pumping station was built at Pelaw Main.
The permanent pumpe were two electrically driven units being "Worthinton" water
pumps, centrifugal type 3DR12. The supplier, "KAB" projects had won the contract
with their quote of $3267.00. The pumps operated at 1450 revolutions per
minute to produce two hundred (200) gallons per minute for an eighty (80') feet
lift. Two ten (10) H.P. Brooks Dripproof motors (450 Volts, 3 phase, 50 cycle)
were use to drive the pumps. On 12th October, 1977 the "Worthington" water
pumps at a cost of $733.00.
