4 Steps In The Process Of Drilling Boreholes (Water well)

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 a borehole:

#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 such as pipelines or cables.

#2 Drilling and Construction

The next step is to commence with the drilling. Specialized 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, up to 300m deep. Construction comes next in by inserting a steel casing to reinforce the and secure the borehole from collapsing.

#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 specifications of the pump you need. The installation and type of system will largely depend on the intended use of your new borehole. If your domestic borehole will be used for drinking water, a filtration system is needed to get rid of contaminants from your water supply, if the water test results prove it to be necessary.

• Purpose of borehole – will the water be used for irrigation, domestic usage or as reserve supply.
• Flow rate – means the amount of water to be moved and pressure required to get it where needed.
• Distance the water needs to travel – from under the ground to the top of the borehole, and from there to your tap.
• Refill rate – the water level in your borehole drops when pumping and will refill whilst the pump is off.
