List of Boreholes in Botswana
What is Boreholes?
A borehole is a narrow shaft bored in the ground, either vertically or horizontally. A borehole may be constructed for many different purposes, including the extraction of water, other liquids, or gases.

Frequently Asked Questions
How much is it to drill a borehole in Botswana?
The average drilling cost is around R 600 a metre, according to the Borehole Water Association of Southern Africa (BWA).
How many boreholes are there in Botswana?
There are more than 25,000 officially registered boreholes in Botswana of which 10,000 are owned by the government for water supply
How many Litres of water can a borehole produce?
A single water well can produce up to 20,000 litres (4,400 gallons) of pure water every day without any permissions or licenses.
Why do boreholes fail?
Iron oxidation and iron bacteria are two of the main factors that have a detrimental effect on borehole pumps. When these contaminants accumulate, they begin to clog and corrode the pump’s parts and can eventually lead to complete system failure.
Do you need a licence for a bore hole?
If you wish to abstract water from an underground source, such as a well or borehole, you will usually require a groundwater investigation consent to construct and then carry out a pumping test before you can apply for an abstraction licence.
Do I need permission for a borehole?
Landowners have a right to access any water beneath their ground. This means there is no need to acquire planning permission to drill a water borehole, thus making it easy for a developer to install a borehole during a property build process.
Do you need a water use license for a borehole?
Registration is required if the intended abstraction volume falls within the quaternary catchment’s General Authorisation limit (but is not a Schedule 1 type use); and, authorisation (water use licence) is required for volumes exceeding the quaternary catchment’s General Authorisation limit.
Can I drill my own borehole?
Boreholes typically require installation by a specialist company – such as Teckna Group – but you may be wondering: is it possible to drill a water borehole by yourself? The short answer to this question is: no!
What is the maximum depth of Borewell?
The deepest known borewells in Bangalore now are at depths of over 1700 feet. Shallower ones exist at 100 feet. In Bangalore’s geology, deep aquifers start in most places at depth of about 100 feet, in the hard rock layer.
Can a bore run out of water?
In most situations, your bore is unlikely to dry up instantaneously. Generally, there would be a gradual decline in the water level over time. However because water levels in bores are often not monitored, it may appear as an instantaneous decline because the pump will stop.
How do you stop a borehole from collapsing?
It is well known that borehole collapse occurs when the mud weight is too low and because the hoop stress around the hole wall is very high. This is often resulting in rock failure (Aadnoy and Chenevert, 1987). The most important remedy is to increase the mud weight.
What are the problems with borehole?
Borehole stability problems can result from damaged casing and screens, borehole wall collapse, corrosion or excessive water velocities into the well. High water velocity can cause formation particles, like sand, to flow into the well, causing eventual collapse of the borehole wall.
