Drilling for water
Drilling for water involves substantial financial outlay. Many
dollars have been wasted by landholders commencing
drilling without considering important details which can
determine the success of a drilling program. This step-by-
step fact sheet will put you on track towards making the
correct decisions in developing a reliable groundwater
supply, whether it be for stock, domestic or irrigation
Before you contact a driller, there are a number of
questions that should be addressed:
• How much and what quality water do I need?
• What supply and water quality can be expected?
• What depth will the bore need to go to?
• What will it cost me?
• What type of drilling rig will be needed?
• Where is the best bore site on my property?
• Do I need a permit to drill a bore?
• How should the bore be designed?
The Department of Natural Resources and Water (NRW)
may hold information on previous drilling in your area.
Contact your local NRW office to determine if drilling or
water bore records are available.
You can also seek advice from a private hydrogeological
consultant who can provide a groundwater assessment on
Assessment of potential groundwater supplies will include
likely maximum depth, expected water quantity and quality
and preferred drilling sites.
Drilling contractors can be a good source of information
especially if they have a good working knowledge of a
You can make your own assessment if there are existing
bores nearby. If they are located in the same geological
and topographic setting then you could expect a similar
result. It is best to find out as much information as you
can on these bores including depth, strata penetrated
and any dry holes drilled.
Water divining—does it work?
There is no scientific evidence to support the claims of
diviners that their methods work. In fact many 'divined'
sites have proven to be failures, although it is fair to say
