The Science Behind Boreholes: How They Work and Why They're Reliable
Understanding the Basics
A borehole is essentially a hole drilled into the ground to access groundwater.
The Drilling Process
Borehole drilling involves a complex process that requires specialized equipment and skilled technicians.
- Site Selection: The first step is to identify a suitable location for the borehole.
This involves geological surveys and hydrogeological studies to determine the presence and depth of groundwater. - Drilling Rig Setup: A drilling rig, a powerful machine, is set up at the chosen site.
- Drilling Operation: The rig's drill bit penetrates the Earth's layers, creating a cylindrical hole.
As the drilling progresses, drilling mud is circulated to cool the bit, remove rock cuttings, and stabilize the borehole walls. - Groundwater Encounter: Once the drill bit reaches an aquifer, a layer of rock or sediment that can store and transmit water, groundwater flows into the borehole.
- Casing and Development: A casing, a strong pipe, is inserted into the borehole to prevent collapse and contamination.
The borehole is then developed to improve water flow by removing fine particles and sediment.
Why Boreholes Are Reliable
Boreholes offer a reliable and sustainable source of water for several reasons:
- Consistent Water Supply: Groundwater is a relatively stable resource, less susceptible to seasonal variations in rainfall compared to surface water sources like rivers and lakes.
- Improved Water Quality: Groundwater is often filtered naturally as it passes through layers of soil and rock, resulting in better water quality.
- Reduced Reliance on Municipal Water: By having your own borehole, you can reduce your dependence on municipal water supplies, which can be unreliable or subject to water shortages.
- Environmental Benefits: Boreholes minimize the environmental impact associated with water extraction from surface sources, such as river diversions and dam construction.

Fact 1: Know Your Borehole Casings
The Preferred Borehole Casing In Zimbabwe Is Class 9 and 10 (Pressure Classes.)
This is because Class 9 and Class 10 Casings are more collapse resistant. The strength of a Casing is often described as collapse resistance.
Fact 2: Borehole Drilling Depth
The exact depth, of where the water is located, cannot be established by the drilling contractor nor the Water Surveyor (Borehole Siter).
Fact 3: There Is No 100% Guarantee
It is important to note that it is never a 100% guarantee that any hole will yield water, the amount and water quality can also not be guaranteed by the drilling contractor and water surveyor.
Fact 4: Siting Is Important
Making use of a hydrologist or traditional water diviner will increase your chances of having a successful borehole that will yield a sufficient amount of water.
Fact 5: Know The Risks
The risk of the borehole drilling lies with the property owner. The client will still be liable for the drilling costs irrespective of a borehole yielding water or not.
