Q. We are considering a bore, however
some people have told us there is no water underground
and what's there is salty. Other neighbours
are using bore water with lovely green gardens.
We are a little unsure as to how to proceed?
A. Records are available about
water quality of bores in surrounding areas,
as well as depth etc. This information is available
via the link http://www.dse.vic.gov.au/waterdata.
Bores are listed by parish and information is
available free. As we advise all new clients
“ do your research first”. An experienced
driller with a good knowledge of the area should
also be able to advise you.
Q. We have heard that all bores will
have to have meters fitted and people will have
to pay for water. Is this true?
A. This is only true for irrigation
and commercial extraction. Stock and domestic
bores have no requirement for meters. Stock
and domestic usage is set at no more than .1
ML per day, which is roughly 100,000 Lt per
day or 22,000 Gallons per day in the old scale.
Q. We are experiencing difficulties
with a driller for various reasons. He will
not return or answer our phone calls. What do
we do?
A. Contact the water authority that issued
your bore permit and ask for their drilling
inspector. He will be able to advise you as
to the drillers obligations, what is expected
of him and his standard of work. He will also
be able to advise you as to the Minimum Construction
Requirements for Waterbores in Australia (ARMCANZ1997).
Q. We have had a bore drilled and were
told there is “plenty of water”.
The bore is 42Mt deep but that’s all we
know. How do we find more information about
the bore?
A. When a bore is drilled,
both the landowner and the relevant water authority
must receive a “bore completion report”
by the driller. The report will outline all
details of the bore, from depth, yield, geological
conditions, borecasing etc etc. As a matter
of law, these details must be forthcoming from
the driller.
Q. We are considering a bore but have
not decided on a driller yet. What should our
decision be based on?
A. I would suggest two main
things. Use a driller who will provide both
a bore and pump PACKAGE and guarantee them both.
Make it clear you do not wish to pay for the
bore until the pump has been installed, so you
know exactly what you have. Many times we have
heard horror stories of people being told there
was plenty of water, then finding later when
the pump is installed that there is little or
no water. By this stage, the driller has been
paid and is long gone and will not return phone
calls etc.
Q. We had a bore drilled after getting
the cheaper of two quotes. The second driller
asked to see the first quote, promising to “get
under it”. Our bore worked fine for two
days, now it is pumping dirty muddy water for
a short time, then nothing. The driller will
not return our calls and the pump installer
(recommended by the driller) said the problem
is with the bore. What is wrong with our bore
and what do we do?
A. As you have discovered,
cheaper is not better, usually worse, especially
when there is a Labour/Skill/Knowledge/Professionalism
factor involved. I would suggest the driller
did not line the bore to full depth with borecasing,
saving time and materials etc. Or he did not
develop the bore after casing was installed,
once again saving time and fuel etc. If the
driller will not return to rectify the problem,
you will need to have a camera inspection of
the bore to determine how much casing has been
installed. The bore will need to be cased to
full depth and developed as well. The bore may
possibly need a screen or gravel pack (filter
systems) as well. If this is not done, apart
from running out of water, the bore may collapse
and you have lost everything, or continue pumping
dirty water, which will destroy the pump. People
really need to ask themselves what type of work
is carried out by “cut price” contractors?
Q. What sort of Guarantee do you offer
on a bore and pump package?
A. Centre State Drilling offer
a lifetime guarantee on the construction of
the bore and a standard 12 month warranty on
the pump and components. Longer pump warranties
are available on request. On completion of your
installation, you will be given a bore completion
report, pump and motor manuals, proof and date
of purchase/installation and any advice requested
etc. Whilst we can guarantee to find you water,
we cannot guarantee either the quality or quantity
of water.
Q. We have decided to engage your company
to construct a bore for us. What exactly happens?
A. After divining the best
location, the bore will be drilled to the optimum
depth. It will be developed (flushed clean of
drilling slurry), then cased, that is lined
to full depth with not less than class9 PVC
lead free bore casing. It will then be developed
again and flow tested to determine the amount
of water available. Your bore will be logged
to determine different geological formations
and water intersections and flow rates etc.
It will then have a concrete surface seal and
cap fitted, ready for pump selection and installation.
All work will either be in accordance to or
exceed the Minimum Construction Standard For
Waterbores in Australia (ARMCANZ1997). You will
then be given a bore completion report and all
details pertaining to the bore.
Q. We have an existing bore on the
property, about 12 years old, and the flow has
started to diminish in the last few weeks. Is
the bore running out of water?
A. It is possible, however
there are a number of more likely reasons. If
the pump and control system have been checked
and found to be within tolerances, then the
bore may have a buildup of mineral deposits,
such as Iron, Calcium, Manganese or simply sediment.
Either chemical treatment or air development
will resolve the problem and hopefully restore
the bore to its full capacity.
Q. Our bore pump has a pressure controller
connected to our watering system. Even with
the taps turned off, the bore pump still cycles
on and off. Why does this happen and is it bad
for the pump?
A. Your pump operates on a
pressure sensing system. With the taps turned
off, the pump should build up to pressure, usually
40-60PSI, then switch off, not turning back
on until a tap is opened and the pressure drops.
Cycling of the pump is due to either two reasons.
Either there is a leak in the watering system,
stopping it from holding pressure, or there
is air in the system. Either way, the problem
needs to be rectified or it will burn out the
pump.
Q. We want a bore to water our garden,
fill a tank and wash down horses. Will the bore
pump do all these things or do we need more
than one pump?
A. A good bore pump with the right control
system will do all these things. Both the garden
and tank can be filled and watered automatically
and water for washdown also available.
