Generally, this can take up to 3 hours but may vary with the hole. Well head Slab: This is done using cement, sand and gravel in proper ratios to prevent contamination of the hole. Capping: A cap is fitted over the hole until installation of pump.
How long does it take to drill a borehole?
The length of time required to drill a borehole depends on the required depth of the borehole as well as the underlying geology of the site. A general guideline is 1 to 2 days for the completion of the drilling process.
How deep is a borehole in Kenya?

How much does it cost to drill water?
Drilling a well costs $5,500 for an average depth of 150 feet. Most projects range between $1,500 and $12,000. Expect to pay between $15 and $30 per foot of depth, or up to $50 for difficult terrain. Digging might be enough for shallow depths, ranging between $10 and $25 per square foot.
How many years does a borehole last?
A borehole is an asset that should last 50-80 years, with very low maintenance costs in the first 10-15 years. But for this to happen, you need to make the right decisions at the start of the process and invest wisely for long-term returns.
How long do boreholes last?
As a general rule of thumb, a properly installed and sized borehole should last 8-10 years. If you have only just installed a borehole, you’re likely to see years of service from your current equipment. This is extendable with good care and frequent maintenance.
How much it costs to drill a borehole in Kenya?

Do you need permission to drill a borehole?
Borehole drilling for new builds
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.
Can you drill for water anywhere?
If the ground is soft and the water table is shallow,then dug wells can work. … They cannot be dug much deeper than the water table — just as you cannot dig a hole very deep when you are at the beach… it keeps filling up with water!
Can boreholes dry up?
Boreholes can also dry up! Hydro-geologists have cautioned that groundwater has an important ecological function and for that reason its use should be meticulously monitored to ensure that the water source is not exploited.
Can I drill my own borehole?
They are typically installed by a specialist company – such as Teckna Group – but you may be wondering if it’s possible to drill a water borehole yourself? The short answer to this question is, no!
Do boreholes run out of water?
Each borehole will have its own characteristics. Boreholes that are only metres apart can have completely different water levels and delivery capabilities. But, if you and your neighbour are pumping from the same aquifer, over-pumping your borehole could cause their borehole to dry up.

How much is it to sink a borehole?
A borehole installation can cost anything from R60 000 to R100 000, but can cost more depending on how deep you need to drill, the amount of casing used, type of rock that needs to be drilled, ground conditions, equipment and other purpose-for-use related costs.
