How Much Does It Cost to Drill a Water Bore in WA?
If you're thinking about installing a bore for garden irrigation, one of the first questions you'll probably ask is how much it costs to drill a water bore in WA.
For most residential properties, the cost to drill a water bore in WA typically falls between $3,000 and $8,000, depending on several factors such as drilling depth, local geology, and the pump system required.
However, there isn’t a single fixed price. The final water bore cost in WA varies because groundwater conditions across Western Australia can differ significantly from one location to another. Factors such as soil layers, aquifer depth and property access all influence the overall drilling process.
In this guide, we’ll break down the typical cost to drill a water bore in WA, what influences pricing, and why some areas (particularly west of the Darling Scarp) often have favourable conditions for residential bore installations.
If you’re unfamiliar with the drilling process itself, the team at Australind Water Boring & Civil explains the full installation process on our water bore drilling services page.
Typical Water Bore Cost in WA
Across Western Australia, the cost to drill a water bore in WA for residential irrigation usually falls into the following ranges.
These figures reflect typical residential installations across coastal regions and the South West.
What Factors Affect the Cost to Drill a Water Bore in WA?
Several key variables influence the cost to drill a water bore in WA, and understanding these helps explain why prices can vary between properties.
1. Bore Depth
The depth required to reach groundwater is the single biggest factor affecting the cost to drill a water bore in WA.
Because drilling is usually priced per metre, deeper bores naturally increase the total cost.
For example:
Shallow coastal aquifers may be reached at 15–30 metres
Some inland areas may require 40–80 metres or more
Drilling depth depends on local groundwater conditions and geological formations beneath the property.
2. Ground Conditions and Geology
Western Australia has diverse geology, which can significantly affect the water bore cost in WA.
Common ground layers encountered during drilling include:
Coastal sands
Limestone formations
Clay layers
Hard rock formations
Some layers are relatively easy to drill through, while others require specialised equipment or slower drilling speeds.

These differences explain why two nearby properties can have slightly different water bore drilling costs in WA.
3. Pump and Irrigation System
After drilling is completed, the bore needs a pump system to deliver water to your irrigation network.
Pump systems typically cost $2,000 or more, depending on:
bore depth
required flow rate
pressure needed for reticulation systems
irrigation size
Choosing the correct pump ensures the bore runs efficiently and helps avoid unnecessary energy costs.
4. Licensing and Regulations
In some areas of Western Australia, groundwater extraction may require approval or licensing.
Water use regulations are managed by the Department of Water and Environmental Regulation, which oversees groundwater resources across the state.
Information about water licensing and bore regulations can be found here:

These rules usually apply to larger groundwater extraction projects, but it’s always worth confirming local requirements before drilling.
Typical Bore Depths Across WA
One question many homeowners ask when estimating the cost to drill a water bore in WA is how deep their bore might need to be.
While exact depths vary, typical residential bore depths across parts of Western Australia often look like this:
These depths influence the overall water bore drilling cost in WA, since drilling deeper naturally increases labour and equipment requirements.
Why Bore Success Rates Are Higher West of the Darling Scarp
Why Many WA Property Owners Install Garden Bores
Although installing a bore requires an upfront investment, many homeowners find that the cost to drill a water bore in WA can provide long-term value.
Some common benefits include:
reducing reliance on scheme water
lowering irrigation costs
watering larger lawns or gardens
maintaining gardens during restrictions
In areas with suitable groundwater, a bore can provide reliable irrigation water for many years.
FAQ: Cost to Drill a Water Bore in WA
How deep are most residential bores in WA?
Many residential garden bores across the coastal regions of Western Australia are drilled between 15 and 40 metres, depending on groundwater depth and local geology.
How long does it take to drill a bore?
Most residential bore drilling projects can be completed within one day, although installation of pumps and electrical systems may require additional time.
Do I need a permit to drill a bore in WA?
Many small garden bores used for domestic irrigation do not require licensing, but regulations vary depending on groundwater management areas. Checking with the Department of Water and Environmental Regulation is recommended.
How long does a garden bore last?
With proper installation and maintenance, a residential bore can often last 15–30 years or more, depending on groundwater quality and pump maintenance.
Final Thoughts
So, how much does it cost to drill a water bore in WA?
For most residential properties, the cost to drill a water bore in WA typically ranges from $3,000 to $8,000, depending on drilling depth, local geology, and pump installation.
Because groundwater conditions vary across Western Australia, the most accurate estimate always comes from reviewing local bore records and geological data before drilling begins.
For homeowners looking to reduce irrigation costs and maintain healthy gardens, installing a bore can be a valuable long-term investment—especially in areas with favourable groundwater conditions west of the Darling Scarp.
