Whether you’re a home-owner, farmer or industrial business having your own borehole drilled is a big job. It’s one that requires a lot of research, plenty of consideration and you have to be absolutely sure of what you’re getting and how it will benefit you.
With that in mind here are some of the most frequently asked questions about our borehole drilling services we get asked by customers on a daily basis.
How do boreholes reduce/save money?
By tapping into borehole water you essentially remove your dependency on mains water. Borehole water is much cheaper than mains water (with bills continually rising) and although there is the up-front cost of drilling the borehole and mobilising a borehole drilling team in many cases they can be paid back within a year
I have found an old borehole on my property. Can I use it?
In many cases yes, the old borehole will need to be assessed and if it is still producing water than it can be brought back into commission. It may require maintenance works and a cleaning process to re-develop the borehole yield
How deep should a borehole be?
There is no set answer for how deep a borehole needs to be. Put simply the borehole should be as deep as is required to reach the aquifer (water bearing rock). The average depth of a borehole is between 60m and 80m but this can be less as well as significantly more. The depth of a borehole very much depends on where you are based
How far from a septic tank does a borehole hafe to be?
Where possible boreholes should always be a minimum of 50m away from any potential source of contamination such as septic tanks, this is in accordance with Environment Agency guidelines. On some sites this just isn’t possible but as long as the septic tank or other source of contamination is modern and well maintained and the borehole has been constructed properly with sufficient casing then it should be ok.
Will my water be brown?
This can only be determined once the installation has been completed and the water has been tested. In most cases we would be able to give you an indication of your water quality before the installation, based on years of experience.
What is the long term advantage of having a borehole?
The use of ground water takes the pressure of our potable water resources, considerably reducing your Municipal bill as well as adding value to your property.
Can I link my irrigation system to my borehole?
Yes, if requested we can link your borehole to your existing irrigation system provided the water volume is sufficient to operate the irrigation system. Should this not be the case, various options are available to rectify this. Each client's particular needs will be assessed and recommendations discussed.
Is my borehole water safe to drink?
The short answer is a resounding YES! All spring and most bottled water is derived from the ground, while both spring and bottled water sources pump water from boreholes. 64% of South Africans survive on groundwater. If you are going to drink from this water source, we always advise to have it analysed at a water lab just to make 100% sure that it is fit for consumption. A simple SANS-241 test will confirm if the water is potable or not.
Do I need to register my borehole?
No registration is required if the water is to be used for domestic purposes. Borehole water that is used for commercial or agricultural use needs to be registered and metered.
Do I need a filtration system?
The answer to this question depends on the results of your water analysis tests. If you're water test results shows no adverse content whatsoever, we would always recommend a simple ultra violet filter at the point of use if you intend to drink it. However, if you're pumping directly to an irrigation system for example, usually no filtration is required, though a pH adjustment may be necessary to protect your irrigation equipment. Other forms of filtration for example, might be if your test results show high levels of iron, manganese, lead, or any one of a host of other metals, or if your water is excessively hard or soft.
Will my borehole need a pump?
Usually, yes. A submersible pump is electrically operated pump which is located at the bottom of the borehole to bring water to the surface. However, if the underground supply is under pressure, this creates an artesian well where water simply flows out, and which does not require a pump.
How much space is required to drill a borehole?
Our equipment setup varies on the layout of your property, trees, walkways and driveways, etc. When you are ready to schedule the project, we will meet with you onsite before a rig is dispatched, in order to provide you with all the information that you need.
How much does a borehole cost?
There are many factors that determine the final price of a borehole e.g. the depth, the amount of casing installed, the pump specifications and more.
How long does it take to install a pump?
The installation of the borehole pump normally takes one day. The installation of a tank system and booster pump can take an additional day or two.
Should I have a yield test done?
A yield test will determine the amount of water in the borehole and also give you the rate at which it can be pumped. This information is useful so that the correct size pump is installed. If this is done and the correct pump is installed it should give you many years of service.
