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.

If you are interested in drilling a borehole on your property, get in touch with one of the experts at Enviro Boreholes. With over 10-year experience in the industry, you can be sure to receive professional and advice and great service.

  • 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

  1. hey.,i have 2man made boreholes around wangige area in kabete . i would want the same to go deeper by way of machine drilling ,

    please advise me how to make that happen and how much it would cost.both are 90-100ft deep with 17ft water deep.
