REPORT.
Commission of Sewers and Water Supply~ Melbourne,
Engineer's Office, February lOth, 1857.
To THE ColrMISS.IoNERS oF SEWERS AND WATER SuPPLY.
GENTLEl\il<lN,f!i:..
In accordance with your directions instructing me to lay before you a general plan
for supplying the suburbs of the city with water, together with an estimate of the probable
cost, I beg to state that I have again carefully considered the subject, and ~hat I do not see
any reason to induce me to depart from the original plan laid out by me prior to the
commencement of the Yan' Yean Works.
In that plan I laid down one main extending to the western portion of the city (now
laid along Queensberry-strcet) of a sufficient size to supply the whole of North Melbourne,
Flemington, the Moonee Ponds, Williamstown, and, if necessary, Geelong.
A second main along Spring-street (now laid) of a sufficient size to supply not only
the eastern portion of the city, but to allow of its being carried along Flinders-street and all
the wharves to work hydraulic engines, cranes, and hoists, and to supply Emerald Hill and
Sandridge.
.
.
A third main along Victoria-parade (now laid as far as Smith-street) of a sufficient
size not only to supply FitzRoy Ward, but East Collingwood, Richmond, South Yarra,
Windsor, Prahran, St. Kilda, Elsternwick, and Brighton.
In addition to the precaution taken of making each main of sufficient calibre to allow
for extensions, provision has been made on the line of main pipes between Y an Y ean and
Melbourne (by laying down branches at intervals varying from half-a-mile to a mile) for
supplying the various townships on the line, and I am convinced that Preston, Northcote,
Pentridge, and Brunswick can be supplied from your main for a very small sum.
In the extension of· the works it will however now be necessary to consider what
districts are to be supplied from Y an Yea:1 and what are not. If, for instance, Gcelong and
Williamstown (or either of them) are to be supplied from that source, it will be necessary to
consider that the continuation of the western main ft•om Howard-street must be made of such
a size as to meet the requirements of the case ; and in the estimates appended for the supply
of North Melbourne I wish that it should be understood that I have considered what would
be the cost of a main sufficiently large for the supply of North Melbourne, or more properly,
that portion of _it known as Hotham Ward, and have set that dovm as the sum properly
chargeable against Hotham Ward; though, of course, if either Williamstown or Geelong be
supplied from the Yan Yean reservoir, the cheapest plan would be to make the continuation
of the western main beyond Ho ward-street of an increased diameter rather than to lay down
a separate main.
,
A separate Commission having been appointed for the purpose of considering what is
·
the best and cheapest plan of supplying Geelong with water, I do not consider it necessary
that I should here enlarge on the subject of the supply of that town, further than that I
still hold the opinions expressed by me upwards of two years ago, i. e., that Geelong might
be well and cheaply supplied from Yan Yean, and that the laying down of waterpipes along
the Geelong Railway would, in addition to supplying Geelong, very much improve a large
district now indifferently supplied, and by inducing persons to settle along the line be the
source indirectly of considerable profit to the shareholders, to say nothing of the important
fact that Geelong could be much more cheaply supplied from this source than any other.
With regard, however, to the advantages to be derived from the use of the water as
a motive power, more especially in such cases as those where it may be made largely available
4
without. running any portion of it to waste, as would be the case were the eastern or Springstreet main extended down Flinders-street and along the wharves, I am of opinion that too
much can scarcely be said.
I simply however at the present moment content myself (having entered upon this
subject at greater length several years ago) with stating, that I propose to eoritinue the
Spring-street main d0wn FEnders-street, to work a large number of hydraulic cranes, hoists
and engines, and to convey the water after having been used as a motive power, by a return
main, over the Yarra, on the Railway Company's proposed new bridge (for the use of which
arrangements might doubtless be made) to Emerald Hill and Sandridge.
The population of Emerald Hill at the present time is alJout 6,500, and of Sandridge
about 2,500, to which should be added a considerable )Dargin for the extension of each, for
which I have allowed in the,estimate !lnnexed. By the third main (if continued), i.e., that
passing down Victoria-parade, the extensive and important -districts of East Collingwood,
Richmond, South Yarra, Windsor, Prahran, St. Kildl.\., Elsternwick and Brighton, can be
SJ.Ipplied ; and I would urge upon your Board the great desirability of extending your
operations in this direction.
·
The superficial area and population of each of these distric.ts is very great ; . and I
3;m of opinion that the period has now arrived when it is necessary to consider the wants of
each and all of them.
·
With regard Lo East Collingwood and Richmond, the course to be pursued is quite·
clear, but on crossing the Yarra a difficulty will arise, inasmuch as the late Council passed a
Bill granting to a certain Company styled the "South Yarra Water Works ComP,~ny,';>
certain rights and privileges. With regard to this Company I am of opinion decidedly, that
sooner or later the district supplied by it must receive its supply from your Board, and the
question will then arise, can your Board supply that district without buying up the interests
of the shareholders constituting this company? .If .not, I believe that the sooner thos!7.
interests are bought up the better· will it be for the community, or at least for that portion of'
it affected by the operations of the South Y arra Comprtny.
,The populati01i residing at South Yarra, Prahran, Windsor,, and St. Kilda, now .
depending entirely upon this Company or the rainfall for their supply of water, may be·
estimated at 22,000 perSOI{S at the present time, and there can be little doub~ that this
population will rapidly increase, so that it has now become a matter of importance to consider
whether this large population shall continue to derive an insufficient and unsatisfactory
supply from the South Yarra Water Works Company, whether that ·Company shall be
induced to extend their operations, or whether your Board shall take such mea.ns, "[>y the
·
sanction of the Houses of Legislature," to effectually supply these districts.
. I am myself firmly convinced that an extension of the gravitation. system from the
Yan Yean source is infinitely the. cheapest and best means <?f supplying all the suburbs of
Melbomne, as well as Williamstown and Geelong. ·No other plan could by possibility be
brought forward for the supply of the suburbs of Jliielbourne with water at the same pre2sure
and in the same volume at anything like the cost ; for supposing, for example, that in the
centre of Prahran borings were taken for the purpose of ascertaining if an Artesian Well
could be found-supposing fqrther, that the first bore was successful, and that the water rose ·
to the surface of the ground-and in five cases out of six in Artesian WeHs the water does.
not rise to the surface, still machinery would be required for the purpose of raising it to. a
sufficient elevation to give a satisfactory column or pressure, and a tank or stand-pipe
·
would be required.
Moreover, having had some experience respectin~ Artesian Wells, I am enabled to·
state positively that there i~ scarcely any. work in which so many r~eks are run and where
there ·are so many cl1ances of del!.y and fatlure.
'
,
The cases of Grenoble and Southampton may be cited amongst many others; and as
I believe an·attempt was made to find an A1;tesianWell at Toorak-the cost of that attempt.
of one bore might, if. generally known, be the means of enabling the public to judge of the
value of Artesi~m Wells in this Colony n,s a means of supplying districts with water.
In some feiv cases they might be found to be successful, but in very few-for in
addition to the great expense w11ich I haye seen la,tely puiDicly put down at a less figure per
foo~ than would pay for the piping at the manufactory, and in addition to the great risk of
having to make several unsuccessful bores before the water is obtained, the surface of the
water ia :1~1 ·\rtcsian Well is liable in ,a season of drought to sink lower every day, and
there have been instances where the water has absolutely disappeared in a single night.
I have simply alluded to the subject of Artesian Wells as at the present time there
appea1·s to be .an impression on the minds of many . Colonists that it would be very. desirable
.to endeavor to supply several districts with water by such wells.
In conclusion; I wish to remark. that the following estimates are sueP, as I feel convinced are sufficient to execut€1 the works· but as mv calculat~ons are based upon the
assumption that the Government . maps supplied to I!lC a~re correct, " which I believe .is the·
case," some little variations might be found 'requisite in getting out the working drawmgs.
5
I would also observe, that I have not considered it necessary to carry pipes through
every street in East Collingwood, Richmond, Prahran, or St. Kilda, but have made such
provisions that subsidiary mains can be laid down at some future time when the population
has increased to such an extent as to render. such a course desirable.
The first estimate is for the cost of laying pipes to complete the reticulation in Smith
and Hotham Wards, and in this estimate the cost of the main along Queensberry-street,
west of Eoward-street, is only put down as what would be sufficient supposing nothing
further than Hotham Ward is to be supplied from it. The other estimates are sufficiently
explanatory.
