Borehole Drilling·February 8, 2026
What a good borehole survey actually looks like
Half of failed boreholes failed at the survey stage. Here's the geophysical workflow we run before we ever bring a rig on site.

Borehole Drilling
Geo-survey, drilling, equipping, and water treatment for sustainable supply.
Reliable water, anywhere
From hydrogeological survey to drilling, casing, equipping, and water-quality treatment — we deliver dependable potable water systems for homes, farms, schools, and municipalities.
A dry hole is the most expensive hole you will ever drill — so our borehole practice begins with data, not intuition. Every project starts with a geophysical survey using vertical electrical sounding and electromagnetic profiling, cross-referenced against regional hydrogeology to site the well with greater than 85% accuracy. We publish the survey report — expected yield, recommended casing depth, pump sizing — to the client before a rig ever moves on site. Then we drill, case, equip, and treat to deliver dependable potable water for homes, farms, schools, and municipalities. We have drilled 480+ wells, and we ring-fence 15% of our annual drilling capacity for subsidised boreholes in underserved communities.

How we work
Our process
01
Survey
VES and EM profiling map subsurface resistivity to site the well on data, not guesswork.
02
Report & plan
We publish expected yield, casing depth, and pump sizing before drilling begins.
03
Drill & equip
Drilling, casing, pump installation, and storage — built for the long term.
04
Test & maintain
Water-quality testing, treatment if needed, and an ongoing maintenance schedule.
