Our Borehole Drilling Charges
So “How much do you charge to dig a borehole?” That’s a common question we get from our clients. It varies on a lot of factors: The main cost of drilling borehole is largely dependent upon the depth and amount of casing that the borehole will require. The type of rock (Geology) that we have to drill through does have some influence as well as the actual ground conditions. Many people think that the easiest way to drill a borehole is through the soft and loose geologies. However, this is not the case, in fact, the opposite is true. This is made more difficult if the hole is collapsing due to the ground being loose and unstable. We use many different methods to prevent this phenomenon from occurring, including use of drilling fluids and additives as well as the installation of temporary steel casing. All these factors add up in the overall cost of a borehole.
We offer our quotes in an itemized and logical manner. Here is what to expect:
1. Geophysical Investigations / Ground Water Survey. Although we prefer doing our own survey, we do accept the report, if you have already done it prior to contacting us provided it’s done by a recognized Ground Surveyor. We will request you to send us a scanned copy of the report for our analysis before giving you the cost estimates of the whole drilling process.
2. Mobilization and demobilization of drilling equipments, materials,personnel and other required supplies.
3. Erecting and dismantling of the unit and camp
4. Cost of drilling. Charged per meter for different diameters. We usually start our borehole drilling at a larger diameter e.g 20.3 cm to allow the casing be installed thro the soft upper regions thereby prevent collapse. The borehole drilling is then continued at 16.5cm through the solid rock to the target depth or water strike.
(a) Drilling of a borehole 8″dia up to 100 metres
(b) Drilling of a borehole 8″dia from 100m upto 200metres
(c) Drilling of a borehole 8″ dia from 200m up to 300 metres
(d) Drilling of a borehole 8″ dia beyond 300 metres
5. Cost for casing and gravel packing the borehole
6. Borehole development by air jetting before test-pumping
7. Cost of supply and installation of well head slab
8. Cost of developing and flushing of the borehole
9. Cost of cleaning up the site
10 Supply and installation of a borehole cap
11. Test-pumping the borehole to determine its yield including recovery measurements
12. Water Chemical Analysis and borehole report
13. Water Filtration / Treatment
14. Cost of a pumping system
15. Service & Backup. Standby time beyond the control of the contractor
*******At a budget of Ksh. 1.2M to Ksh. 2.0M******
Even if you don’t get to hire us to drill your Borehole we will be happy to advise and assist you to get it right the first time. It’s such a pain hiring a unqualified borehole driller only to miss hitting the water. We are very passionate about ground water. We don’t leave your site until all the work is done. The first step for us after contacting us is to prepare and send you a personalized info-pack that we can talk you through making sure that this process goes on smoothly, and if in fact a borehole is even appropriate for you. All our services are professional so there is no quick-fixes or short-cuts. Please furnish us with your borehole drilling details including exact Geographical location by filling out contact form and we will get back to you. Please note that borehole drilling doesn’t come cheap.
