The Prices Of Drilling A Borehole In Zimbabwe - Are You Being Ripped Off?
How Much Does Drilling A Borehole In Zimbabwe Cost? These are common questions. And the answer for each is: “It depends.”
That is not being evasive. It is a sign of just how the geology of Zimbabwe varies, ranging from the sedimentary rocks to the metamorphosed rocks, to the granite intrusions. In addition, Zimbabwe’s groundwater produces varying yields and quality.
It is, therefore, to be expected that boreholes will differ in-depth, their construction, and how they are drilled.
Depth is invariably the main determining factor when it comes to the borehole cost. Most drill quotes are based on metres to be drilled. So whether you are drilling 10m, 100m or 300m will have a significant bearing on the price.
Borehole Drilling Depth In Borehole Cost:
The Borehole Drilling depth will depend on the depth of the aquifer you are targeting. So a good knowledge of the area’s hydrogeology is essential. A sure way to waste money is to drill on and on without knowing exactly what you are targeting. Different drilling methods are required for different formations, and this will affect the borehole cost. In some settings, it’s possible to case off the top 6m of unconsolidated material. That is, using a pipe to protect the open hole – and then drilling down using air percussion.
This is where the drill hammer breaks the rock, and the chips are blown up out of the borehole using compressed air. In alluvial aquifers, mud rotary drilling uses drilling mud to keep the sand from collapsing and a rotating bit to bore through the sand.
Construction: Borehole construction is another big contributor to cost. It is very important that a borehole is constructed appropriately. With an alluvial aquifer, you will need to choose your gravel pack and slot size correctly to avoid it silting up, while in a competent rock formation you will need to decide carefully whether there is a risk of borehole collapse.

The construction of a borehole contributes greatly to water-use costs.
Where there is deep weathering or changes in information competency or lots of clays, Odex drilling is necessary. This method involves pulling down the borehole casing during the drilling process. This keeps the borehole from collapsing, and can also enable you to drill through hard formations.Construction: Borehole construction is another big contributor to cost.

If the driller needs to bring their drill rig some distance to get to you, the establishment cost may be higher.
Site access can also sometimes pose a problem, further complicating pricing the process.
Understand The Price:
Some tips to help you with drilling quotes: Make sure you understand the items listed. If something isn’t clear – ask for advice.
Seek out people in the area who have had boreholes drilled. What they tell you can be very valuable in determining borehole cost.

If you feel a quote is too high, get another one from a different company. Just make sure you are comparing apples with apples. Check the quoted drill depth, the drill method, and the borehole construction to ensure the quotes are for the same things.
Finally, remember the cheapest option is not always the best option. You get what you pay for, and you want your borehole to last. Make sure you design, drill and construct it so that it does just that, even if it costs a bit more.
