Hydrogeological Survey in Kenya
Site assessment using geophysical methods to locate aquifers and recommend the drilling point before any ground is broken.
Every successful borehole starts with understanding what lies beneath the surface. Powerwell hydrogeologists conduct electrical resistivity and related geophysical surveys to map soil and rock layers and identify formations that can store and transmit groundwater.
The survey also reveals fractures, fault lines and weathered zones that often yield strong flows. You receive a technical report with the recommended drilling location, expected depth and estimated yield so drilling is a planned operation, not a gamble.
We work across Nairobi, Kiambu, Nakuru, Machakos, Kajiado, Mombasa, Uasin Gishu, Kisumu, Nyeri, Turkana and other counties. Local geology changes quickly — a neighbour’s successful well does not guarantee the same result twenty metres away.
Survey findings feed directly into WRA permitting, casing design and later pump selection. That is why we treat this as stage one of the sixteen-stage Powerwell process, not an optional extra.
If you are comparing quotes, ask whether a written hydrogeological report is included and whether the same firm will stand behind the recommended point when the rig arrives. Powerwell surveys are designed to be used on site, not filed and forgotten.
Request a survey quote with your plot location, intended use (domestic, irrigation, institutional or commercial) and any existing borehole data. We respond within 24 hours and will not drill until you approve the scope.
Process
- Desktop and site walkover — We review location, intended use and access, then walk the plot to identify constraints, neighbouring wells and likely survey lines.
- Geophysical investigation — Electrical resistivity and related methods map subsurface layers, fractures and weathered zones that can store and transmit groundwater.
- Interpretation and siting — Results are interpreted to recommend a drilling point, expected depth range and qualitative yield outlook.
- Technical report — You receive a report suitable for WRA permitting and for briefing the drilling crew — not a verbal guess.
FAQs
Do I need a survey before drilling in Kenya?
Yes. Skipping a hydrogeological survey is one of the most common reasons boreholes fail, come in over budget, or miss the aquifer. The survey protects your investment before the rig is hired.
Is the survey used for the WRA permit?
Powerwell includes the hydrogeological report, GPS coordinates and intended use in the Water Resources Authority permit application we prepare on your behalf.
How long does a hydrogeological survey take?
Most residential and farm plots are surveyed in a single site visit, with a written report following shortly after. Complex or multi-plot sites may need extra lines or a return visit. We confirm timing when you share the location and intended use.
Can you survey if I already have a preferred drill point?
Yes. We still run a proper geophysical investigation. If your preferred point is weak, the report recommends a better location before you commit the rig.
