4 Steps In The Process Of Drilling Boreholes
Dams are at all-time lows; municipal water costs are rising and people are getting angry. There has never been a better time to examine alternative water sources than right now. Drilling a borehole and becoming self-sustainable might be an option worth considering.
Here’s what you need to know about the process of drilling boreholes:
#1 Borehole siting
Determining where the water is and how to reach it, is the first step when it comes to drilling boreholes. It is crucial to employ professionals for this task to avoid drilling into natural hazards or pipelines and cables.
#2 Drilling and Construction
The next step is to commence with the drilling. Special machinery is used to drill deep into the earth’s surface. While the depth of an average borehole ranges between 60m – 80m, it can vary greatly from one borehole to another. Construction comes next in the form of steel casing to reinforce the borehole.
#3 Yield testing
Yield testing is done to determine the balance between the greatest amount of water that can be yielded from the borehole and the amount of water that flows back from the neighbouring groundwater source. In order to do yield testing, an aquifer test is carried out. A test pump is installed and water is pumped for a fixed time and set of variables to access the water level in the borehole.
#4 Pump and filter installation
Once the yield testing is done, you’ll be advised on the pump you need. The type of pump system will depend largely on your intended use of your new borehole. If your domestic borehole will be used for drinking water, you’ll need a filtration system to get rid of contaminants from your water supply.

- Purpose of borehole – will the water be used for irrigation, domestic usage or to fill up a reserve tank.
- Flow rate – which means the amount of water to be moved and the pressure needed to get it there
- Distance the water needs to travel – from under the ground to the top of the borehole, and from the borehole to your tap
- Refill rate – the water level in your borehole will drop when pumping water and will refill when it rains
