Bores into the confined and semi-confined aquifers go to large depths to produce high quality and quantity of water.
This type of drilling requires more than putting a hole in the ground. There are tight regulations and frameworks that licensees must comply with before, during and after the drilling.
We proudly offer help with the whole process of Mirrabooka and Leederville water bores.
Assessing the property and lodging the application for a bore construction permit with the Department of Water and Environmental Regulation.
Drilling a pilot bore and submitting its wireline log for DWER’s assessment, to then confidently drill into the correct depth and complete any further works on the bore.
Lodging the information of the drilling to DWER, through the corresponding form and supporting bore log with the record of soil samples taken every 2 metres.
The process is complex. We take care of each and every step.
One of the most important aspects of drilling a deep confined high quality water bore is high-quality equipment and highly-skilled drillers.
It takes longer to drill, so we have Level 2 drillers with precision skills that operate hybrid rigs, appropriate to get through the different soils and build a bore at the optimal depth. We are ADIA members and certified.
Drilling is not just putting a hole in the ground, especially when going into confined and semi-confined aquifers. We take care of all the documentation with the Department of Water and Environmental Regulation. You can be involved as much or as little as you want.
For you, drilling can be just making use of your hole in the ground.
We can get you to high-quality water with a healthy water bore that will serve you for years to come.
We construct bores and select materials based on your needs. We only ever use quality materials, from stainless steel screening to PVC casing, to ensure a reliable and sustainable water supply.
You don’t have to worry about it. We can take care of the whole drilling process, from the application forms, to planning and executing the drilling, and following up with DWER.
We have large rigs, sized to the appropriate drilling technique and required depth to reach the confined and semi-confined aquifers safely and effectively.
We want your system to operate optimally throughout its lifespan. All of our bores are constructed with the highest quality materials and techniques in the industry.
What our clients and drillers say about us.
We offer both of those free. We will offer a quote once we have had time to go through a consultation with you, and in some cases view the property. This will ensure you get the most accurate quote possible. It also provides us with an opportunity to get to know you and your needs.
If the quote cannot be provided without testing your bore or system, we will discuss the costs of these services before doing anything, to ensure you are informed of any costs associated.
Depending on the depth of the drilling, the construction of the hole itself can take longer.
Generally, for the Standard Superficial Aquifer or the Perth Hills Fractures, it takes us one day to drill and construct the bore. We can arrange to get your pump installation and connection to irrigation system the next day. In all, the project takes about 2 days.
Bores into the Mirrabooka and Leederville Aquifers are a longer process, as they require a pilot bore so that a wireline log is conducted and sent to Department of Water and Environmental Regulation for their approval, before the final bore and construction can be finalised. In this case, the project takes about a week once the drilling itself commences.
An aquifer is a body of water below the ground that is made of permeable rock, soil or clay that enables water to flow through it. Aquifers are generally referred to as confined and unconfined.
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.
We recommend you contact us directly so we can provide advice specific to your situation, to ensure you are compliant with the legislation applicable to you.
Most residential bores do not need a licence to be drilled and utilised.
If you are doing any of the following you'll most likely need a groundwater licence to take water:
Another type of licence is a 26D licence to drill a borehole, which you need in case you are:
The Department of Water and Environmental Regulation offers a flow guide as to whether you require a license or not.
