Best borehole drilling company
As a leading borehole drilling company in Kenya, we not only drill wells but thoroughly guide farmers on what is needed to procure borehole drilling services from Grekkon Limited. When the borehole is complete, we provide a borehole water pump that evacuates water to a storage unit. Our borehole pumps are submersible solar or electric types. In this piece, we provide a breakdown of the average cost of drilling a borehole in Kenya depending on the drilling method adopted
Requirements for drilling a borehole in Kenya
Borehole drilling process
- Conduction of a hydro-geological survey to establish the point of drilling, depth, rock structure and amount of water present beneath
- Review of the hydro-geological survey report
- Client submission of licenses and permits from; Water resource management authority (WARMA), National environmental management authority (NEMA), and the county government (if the county government must approve)
- Physical site visit for logistics assessment
- Generation of a detailed quote
- Down-payment of 75% of the total amount
Our borehole drilling price in Kenya varies with the drilling method, which is determined by the rock structure. Below is an indicative price tabulation

Note that the mobilisation cost varies with the location. The cost of drilling a borehole in Nakuru will be different from the cost of drilling a borehole in Wajir
How to drill a borehole in Kenya; What the drilling cost entails
This is the transfer to the well site of the rig, equipment, and labor. We cost mobiliation by distance. A borehole project 500kms away from our office will pay more for mobilisation than one that is 50kms away
This is the actual process of sinking a well in the ground in order to obtain water. The depth of sinking depends on the reading of the hydro-geological survey report. This report states the depth, amount of water expected, and the geological structure of the soil and rock underneath. The normal size of the borehole is 8 inches in diameter, but the surface section is 10 inches.
We line the walls of the borehole with mild steel casings. This is to keep the wall from collapsing throughout the lifetime of the borehole. There are 2 types of casings3.1. Continuous casings. They line the sections where the aquifer(s) is absent
3.2. Slotted casings. They line the aquifer sections to allow water into the well. The slots are 1mm to 2mm in size
It is the application of gravel sand between the borehole walls and the mild steel casings. Gravel filters soil and other impurities and keeps the casings firmly in position
5. Well development and capping
The well is cleaned of all debris and sealed at the top with a cap to prevent dirt and other material from getting in
6. Test pumping
We draw out borehole water for 24 hours. This shows the yield of the well, recharge rate and water level. It is with this report that we determine the right solar or electric submersible water pump
7. Water chemical analysis
Laboratory analysis of the chemical composition of the borehole water
Borehole Drilling Questions
FAQs to Borehole Drilling Services in Kenya
As the best borehole drilling company in Kenya, we tailor our price according to the hydro-geological survey result finding.
How many meters is a borehole?
From 50M and below, a well qualifies as a borehole
What is the average depth of a borehole in Kenya?
None. This is by location only because the variances are large.
How do you know where to drill a borehole?
Through a hydro-geological survey by an independent hydro-geologist. It determines; water availability at which point, how much water, and at what depth
How long does a borehole last?
It lasts in as much as the water table or aquifer remains
What is a good borehole yield?
It depends on water usage. For domestic use, a yield of 2 cubic meters per day is sufficient for a homestead. For farming, a higher yield is better
Can a borehole be drilled anywhere?
No. Only where there is a water aquifer. This is why a hydro-geological survey is conducted to show exactly where the water source is
Can borehole water run out?
Yes it does when the water aquifer dries up
Do I need permission to drill a borehole?
Yes, permission must be sought. 3 certificates and permits are needed in order of priority listed below
- Water Resource Management Authority (WARMA) certificate
- National Environmental Management Authority (NEMA)
- County government permit (in conties that demnd this)
Besides drilling, Grekkon Limited’s agronomy team will design a crop irrigation system for all borehole clients without charge. We provide a detailed crop growing program with on the ground agronomy support for the first season of the crop
