We understand how to overcome the challenge of Perth Hills water bore drilling. BD Water is experience in Hills drilling.
The changing soil and uneven ground of the Perth Hills make the bore drilling process a different type of job.
We use custom made hybrid rigs for these jobs.
It’s rocky, it’s difficult to drill due to the nature of the soils including fractured rock, which is hard to break through, so we need to use the air hammer type of drilling to get through the tougher parts. The clay and granite require a less abrasive type of drilling.
For these reasons, we use specified hybrid drilling rigs that include Air Hammer and Mud Drilling processes, so that we can get through whatever materials we find.
Uneven topography is par for the course in the Perth Hills. When drilling a Hills water bore, the first step is to find the right site and determine accessibility. The drill rig is a large assembly, mounted on a rigid truck and with a support truck. From there, the rig is set up and drilling can begin.
It’s an unforgiving area, but we have the skill and expertise to deal with it.
We are very upfront with the challenges of drilling in the Hills and risks involved for all parties.
We deliver as best as possible, and we do everything in our power to find water, but if it physically doesn’t exist – and that is a real possibility – there’s nothing we can do.
It’s difficult to predict where water is in the majority of soils, but it gets even more complicated when dealing with water bore drilling in the Perth Hills, where we're looking for water in a rock fracture.
Our experienced and highly skilled drillers take soil samples every 2 metres to determine if we’ll find water, and which type of drilling to use.
Due to the inconsistency of materials, it’s necessary to apply different drilling techniques.
We have custom built our rigs especially for drilling through different layers of soil and to cope with the variety of soils of the Perth Hills water drilling, namely the clays and muds, as well as the rock.
Not every driller is the same. Drilling is an artform, especially in the Hills. It requires experience and craftsmanship to overcome the challenges of the soils in the Perth Hills.
Our drillers are some of the most experienced in the business and specifically in Hills drilling. We have a highly knowledgeable team, and we are used to and tailored to drilling in the Hills.
Our custom rigs are built to swap between processes for different soils efficiently. We are always investing in equipment, to make sure we are on the cutting edge of the industry.
What our clients and drillers say about us.
Our rigs are custom built for drilling in all types of surface around Perth.
For the Perth Hills, we have designed and built hybrid rigs, which apply a technique of Mud Rottary drilling for the clays and sandy soils, as well as a Air Hammer process for the rock layers. This ensures the drilling process is as smooth as possible, even in these surfaces.
No, not everywhere is suitable for a water bore. This is particularly relevant in the Perth Hills, where there are no aquifers, but rather rocks and water bodies in their fractures. The drilling technique in these conditions is aiming at intersecting a stream of water in those fractures.
There are certain factors that contribute to a higher chance of finding such water bodies, particularly the altitude of the Hill. Our drillers are experienced in this soil type, and they will happily suggest the better location in your property for the drilling. We are also happy to work in a location of your choice.
Finding water isn't certain, but selecting the best location will increase our odds.
It’s possible to drill in your front yeard or driveway. No lawn access doesn’t mean it’s impossible for you to have a water bore installed.
We can discuss the best option for your property and drilling needs during your free consultation.
In the majority of suburbs, we have a good level of confidence. However, there are some exceptions.
A water bore pulls water from an aquifer or groundwater body, so one needs to be physically present in your property. In some cases, particularly in the Hills, one house can have a consistent and plentiful water supply, and the next door neughbour can't find water!
We are happy to discuss this further if you contact us. It’s always best to take steps to ensure your property is suitable before we go any further in the consultation process.
It depends heavily on what you're looking to achieve with the bore and where you're drilling it.
Costing is generally worked out on a per meter basis, which will include drilling the bore, inserting the PVC casing and air developing of the bore until the water is clear of any muds.

Depths can vary depending on the area:
If your area is mapped by the Department of Water and Environmental Regulation, you can get a guide for what depth you should expect for the superficial aquifer. The water maps aren't always correct - we'll be happy to give you insights into drilling in your are that we gather from our drilling jobs in your area.
This can vary heavily, mainly it depends on where you’re drilling and what aquifer you’re targeting.
As a general guide:
The Department of Water and Environmental Regulation offers a guide map with the expected depth of the water bodies present in specific locations. Some areas are unmapped, as there is not sufficient information to estimate the depth of the aquifers. In the Perth Hills, drilling is slightly different, as we are targetting a fracture between rock bodies, and not an aquifer, so this area is never mapped.
This map is only a guideline for the depth of the drilling. Our drillers take soil samples every 1-2 metres to ensure we drill to the optimal depth for the best producing bore, so the depth can only be exactly determined during the drilling.
