Estimated costs of borehole drilling services in Kenya
Pricing varies by county, method (air vs mud‑rotary), depth, and contractor, but recent estimates give a useful baseline.
Typical cost components (per project)
For a typical Nairobi‑area borehole drilled to 60–100 m using the air‑drilling method, total project costs often fall between KSh 1M and KSh 2M, depending on pump choice and tank size.
Example cost breakdown (Nairobi‑based project)
A 80‑meter borehole using air drilling therefore runs roughly KSh 536,000–670,000 for the drilling and related field work, before pump and tank costs.
How to choose the right borehole drilling company
When selecting among borehole drilling companies in Nairobi and Kenya, consider the following:
-
Licensing and registration: Confirm registration with WRA and the relevant county and ability to obtain permits.
-
Experience and references: Ask for past projects in your area and check reviews or case studies.
-
Survey‑first approach: Avoid firms that skip or downplay hydro‑geological surveys; this increases dry‑hole risk.
-
Written quotations: Request itemized quotes that separate survey, drilling, casing, testing, and pump costs.
-
After‑sales service: Warranty on pumps, maintenance options, and emergency call‑out availability.
