Drilling Procedure

Step-by-step guide to the borehole drilling lifecycle in Kenya: scientific hydrogeological siting, statutory WRA and NEMA permitting, precision drilling, 24-hr test pumping, and system commissioning.

Drilling Procedure

Our borehole drilling process

We follow a structured, professional borehole drilling procedure to ensure safety, reliability and long-term performance of every borehole we construct.

1
Hydrogeological Survey & Permits
A hydrogeological surveys analyse subsurface geology and aquifer properties to determine the best drilling location and depth, supporting EIA, WRA and NEMA permit applications.
2
Drilling Equipment Mobilization
Once payment is settled, drilling rigs and support equipment are mobilized from the operations base and sent to the borehole site for drilling work.
3
Borehole Drilling & Construction
The drilling rig is positioned at the identified point, a rotating bit cuts through formations, gravel packing is added and steel casing installed to stabilizes the borehole.
4
Water Testing & Pump Test
A 24‑hour chemical and yield test confirms water safety for domestic, commercial and agricultural use, after which we size and quote final pumping equipment.
