Is a Commercial Water Bore a Good Investment for Your Business in WA?
For many businesses in Western Australia, water is a significant operating cost. Irrigation, washdown, dust suppression and landscaping can consume large volumes of water, especially during long dry summers.
As water costs continue to rise, more business owners are asking whether a commercial water bore is a worthwhile investment. The answer depends on your water demand, location and long-term operating goals, but for many businesses the combination of lower ongoing costs and improved water security makes a bore an attractive option.
This guide explains which industries commonly use commercial bores in WA, how the economics typically work, and why location, particularly west of the Darling Scarp, can have a major impact on project viability.
Good investment
Often a strong fit when annual irrigation or process-water use is high
Commercial bores are most commonly justified by high ongoing water demand, reliable groundwater availability and a multi-year ownership horizon. Properties west of the Darling Scarp often have the strongest groundwater conditions.
Who Typically Uses Commercial Water Bores in WA?
Before looking at costs and return on investment, it helps to understand which types of businesses commonly rely on groundwater.
In Western Australia, commercial water bores are often used by organisations with substantial outdoor water demand or high ongoing scheme water costs.
| Industry | Typical Bore Water Uses |
|---|---|
| Agriculture & Farming | Irrigation, stock water, washdown |
| Vineyards & Orchards | Crop irrigation |
| Caravan Parks & Holiday Parks | Lawn and landscape irrigation |
| Sports Clubs & Sporting Grounds | Ovals, turf management and grounds maintenance |
| Schools & Educational Facilities | Playing fields and landscaped areas |
| Industrial Facilities | Dust suppression, washdown and process water |
| Lifestyle Developments & Acreage Estates | Shared irrigation systems |
| Local Governments | Parks, reserves and public open spaces |
| Golf Courses | Turf irrigation and course maintenance |
Many of these organisations use large volumes of water throughout the year, making groundwater an attractive option for reducing operating costs and improving long-term water security.
The suitability of a commercial bore depends on factors such as groundwater availability, expected water demand, local licensing requirements and the property’s location. In many parts of coastal Western Australia, particularly west of the Darling Scarp, groundwater conditions can make commercial bore projects highly viable.
Why Businesses Consider Commercial Water Bores
Commercial bore projects are usually driven by three factors:
1. Reducing ongoing water costs
If you’d like to explore whether a commercial bore is likely to deliver meaningful savings for your property, a local assessment is the most reliable place to start.
2. Improving water security
A dedicated groundwater source can provide greater control over irrigation and operational water use, reducing dependence on external supply restrictions.
3. Supporting long-term operations
Businesses that expect to remain on a property for many years often view a bore as infrastructure that supports ongoing operations and property value.
Commercial Water Bore vs Scheme Water
| Factor | Commercial Water Bore | Scheme Water |
|---|---|---|
| Upfront Cost | Higher initial investment | Lower upfront cost |
| Ongoing Cost | Primarily electricity and maintenance | Ongoing water usage charges |
| Water Restrictions | Often more flexible for irrigation (subject to regulations) | Subject to watering rosters and restrictions |
| Water Quality | Untreated, varies by location | Treated and potable |
| Long-Term Cost Control | Potentially strong | Less predictable due to future pricing changes |
For irrigation-heavy businesses, the lower ongoing operating cost is often the primary financial driver.
What Determines the ROI?
| Factor | Effect on ROI |
|---|---|
| Annual Water Usage | Higher usage generally improves ROI |
| Groundwater Availability | Reliable aquifers improve project viability |
| Drilling Depth | Shallower bores typically reduce installation costs |
| Pump Efficiency | Lower energy consumption improves returns |
| Property Ownership Horizon | Longer ownership generally increases value |
| Regulatory Requirements | Licensing and approvals can affect costs and timelines |
Return on investment varies widely, but the main factors are relatively consistent.
As a general rule, businesses with high and consistent irrigation demand tend to see the strongest financial case for a bore installation.
Why Location Matters
One of the biggest factors affecting commercial bore viability is whether the property is located west or east of the Darling Scarp.
West of the Darling Scarp
Coastal areas west of the scarp are typically underlain by:
Sandy soils
Limestone formations
Sedimentary aquifers
These conditions generally provide:
Shallower groundwater
More consistent aquifers
More predictable drilling depths
This is one reason Australind WBC reports 99%+ success rates in suitable areas west of the Darling Scarp.
East of the Darling Scarp
Inland areas are often dominated by:
Granite
Metamorphic rock
Fractured aquifers
Groundwater can still be found, but drilling outcomes are generally less predictable and may require deeper exploration.

Licensing and Compliance
Commercial bore projects are often subject to different regulatory requirements than small domestic garden bores.
Depending on extraction volume and intended use, you may need:
Groundwater licensing
Approvals for commercial extraction
Ongoing compliance with licence conditions
These requirements vary by groundwater area and intended use. Early assessment is important to avoid delays later in the project.
Typical Commercial Bore Depths
Depth varies significantly by location and geology.
| Location Type | Typical Commercial Bore Depth |
|---|---|
| Coastal South West | 20–60 m |
| Semi-Rural Areas | 30–80 m |
| Inland / Fractured Rock Areas | 80 m+ |
These are indicative ranges only. Site-specific investigation is always required.
When Does a Commercial Bore Make the Most Sense?
A commercial water bore is often worth considering when:
Annual irrigation or process-water use is high
Scheme water costs are a significant operating expense
The property is expected to be held long-term
Groundwater conditions are favourable
Reliable irrigation is important to the business
It may be less attractive when water use is minimal, groundwater access is uncertain, or the property is short-term.
| Situation | Commercial Bore Suitability |
|---|---|
| Large irrigation demand | High |
| Sports grounds and public open space | High |
| Caravan parks and resorts | High |
| Agricultural operations | High |
| Low annual water consumption | Lower |
| Short-term property ownership | Lower |
| Areas with uncertain groundwater availability | Lower |
| Properties west of the Darling Scarp | Typically High |
How Australind WBC Evaluates Commercial Projects
Australind WBC approaches commercial projects differently from a simple drilling quote.
The assessment typically includes:
Review of local bore records
Geological mapping
Groundwater data analysis
Expected water demand
Pump and system sizing based on actual performance data
This helps determine not just whether water is available, but whether the project is likely to deliver the performance and economics the business expects.
To understand the process in more detail, see Australind WBC’s water bore drilling services or request a property assessment .
Final Summary
So, is a commercial water bore a good investment for your business in WA? In many cases, yes, particularly for businesses with substantial irrigation or operational water demand and properties located in favourable groundwater areas west of the Darling Scarp.
The strongest financial case usually comes from:
High ongoing water usage
Reliable local groundwater
Long-term ownership
Well-designed bore and pump systems
Because every property is different, the best next step is a site-specific assessment that evaluates groundwater availability, expected yield and overall project viability before drilling begins.
If you’d like to explore whether a commercial bore is likely to deliver meaningful savings for your property, a local assessment is the most reliable place to start.
