PROLOGUE
First
settlement in Port Phillip
The original settlement in Port Phillip was at Sullivan’s Bay, near Sorrento,
in 1803. Water was supplied to the 400 marines, convicts and settlers via 6 wooden barrels sunk into the ground to capture
groundwater.
In 1835 John Batman officially claimed the establishment of the Town of Melbourne. Within five years
the population of the town was 7,000 and water pumps were installed on the northern bank of the Yarra River, above the falls
(the falls prevented salt water flowing further up the river). Men with water carts travelled the town door-to-door selling
water at three shillings a barrel.
As the town continued to grow it became apparent that pollution from human settlement
and the limited availability of good quality drinking water were presenting significant health issues and would limit the
future growth of the settlement.
In 1842 the newly-formed Town of Melbourne Council was given responsibility for water
and sewerage for the Town but it did not have the taxing or borrowing powers or resources to be able to carry out the undertaking
effectively. The Council lobbied the Government (then based in Sydney) for funds but they were loathe to hand over such large
amounts to the new body.
By late 1849 James Blackburn's privately owned Melbourne Water Company was pumping water
from the Yarra River into large iron tanks in the City. The water was filtered through charcoal and sand and sold to water
carriers for distribution in horse-drawn water carriers.
Early Water Distribution System
The
system is described in more detail as follows:
"In 1849 James Blackburn and J. W. Peppers formed a partnership known as the "Water Company"
to construct a water works at the junction of Elizabeth and Flinders Street. A large trunk brought water from the Yarra to
a reservoir in the centre of their premises. From there a steam engine pumped the water to another reservoir at one end of
the building which was raised about six feet from the ground. From there it was filtered through sand and charcoal and passed
into a tank from which it was able to flow by means of tubes into water carts below. Eight carts could be loaded at once,
with each cart being filled in 30 to 40 seconds. The planned price per load was said to be one penny. However when operations
commenced in early September 1849 the price was set at a halfpenny more".
Blackburn was an experienced
engineer from London who had been transported to Tasmania as a convict but earned his freedom. He designed and supervised
the construction of Launceston's water supply system and devised a plan for Hobart's water supply system, before moving to
Melbourne in 1849. He was probably the most innovative and skilled engineer in the Colony at the time and was soon appointed
to the position of City Engineer at the Town of Melbourne Council.
Blackburn began surveying sites for possible future
water supplies for Melbourne in the late 1850's. Initially, Blackburn chose the Plenty River as the next supply source for
Melbourne's water - he was planning for a population of 70,000 people requiring 40 gallons per day each (Melbourne's population
at the time was only 23,000 and the rapid growth resulting from the gold influx had not yet occurred).
Blackburn was
distrustful of "modern machinery" and preferred to use the simple and time-proven method of moving water by gravitation "as
extensively practiced by the ancients". He sought to find a water source at sufficient elevation then "diverting the same
from its natural course and by means of an aqueduct, open or closed, leading it on a series of inclines to its destination".
It was this view that provided the foundation for the subsequent development of Melbourne's extensive network of aqueducts.
The capital cost of such a system would be greater than other alternatives but the operating costs and reliability of such
a system were considered to be much preferred.
