A borehole site assessment — also called a hydrogeological survey or borehole siting survey — is a professional evaluation of your land before any drilling begins. It identifies the best drill point on your specific plot, predicts the likely depth and yield, flags water quality risks, and produces a written report. Done correctly, it is the single most cost-effective investment you can make in a borehole project.
The evidence: A study of 2,788 boreholes in Ghana's Ashanti Region found a 91% success rate when boreholes were correctly sited on the right geological zone. Without a survey, success depends on luck — and the same formation can swing from productive to completely dry over a horizontal distance of just 10 metres.
What Happens During an Assessment
- Desk study — we review CSIR-BRRI hydrogeological maps, satellite imagery and local drilling records before visiting your site
- Site walkover — our geologist observes surface geology, drainage, vegetation and topography to identify water-bearing zones
- Best drill point marked — optimal location physically marked on your plot with GPS coordinates recorded
- Water quality risk flagged — regional issues (iron, fluoride, salinity, bacteria) identified so you can plan treatment
- Written report delivered — within 48 hours, suitable for bank, donor or building permit submission

Is a site assessment the same as drilling?
No. An assessment is a pre-drilling survey — no drilling equipment is used. If you proceed to drilling after, that is a separate service.
How long does a site assessment take?
The site visit typically takes half a day. The written report is delivered within 48 hours.
Can AquaProbe also drill after the assessment?
Yes. AquaProbe conducts the site assessment and, if you choose, drills the borehole at the recommended point — full turnkey from survey to water-on-tap.
