A hydrogeological survey is the foundation of every successful borehole project.
Drilling a borehole without a professional hydrogeological survey is one of the most expensive mistakes a property owner can make. Surveys are an essential investment that saves money, protects your aquifer, and ensures you drill in the right location with confidence.
At Kisima Well Drillers, our hydrogeological surveys combine advanced geophysical instruments, scientific field methods, and decades of professional experience to identify the most productive water zones, estimate sustainable yields, and assess water quality before you invest in drilling.
Why Hydrogeological Surveys Are Critical
Without a survey, you're making blind assumptions about your geology. Surveys eliminate guesswork and provide scientific certainty.
- Optimal Drilling Location: Ensures you drill in the most productive area
- Reliable Yield Estimates: Know exactly how much water your aquifer can deliver sustainably
- Water Quality Pre-Assessment: Identifies potential contamination before drilling
- Cost Planning: Calculate complete project cost accurately
- Multiple Aquifer Mapping: Identifies at least 3 separate water-bearing zones
- Long-term Sustainability: Ensures your borehole will deliver reliable water for 20+ years
Risks of Drilling Without a Survey
Drilling without a survey is extremely risky. Clients who skip surveys often encounter:
- Dry Boreholes: Drilling in the wrong location wastes thousands
- Excessive Drilling Costs: Drilling too deep multiplies expenses
- Poor Water Quality: Unknown contamination discovered too late
- Oversized Pumps: Selecting pumps without yield data damages equipment
- Aquifer Depletion: Pumping unsustainable volumes dries up the borehole
- Wasted Investment: A failed borehole is an expensive dead loss

Regional Geology Overview
We've conducted surveys across all 47 Kenyan counties, adapting our methodology to diverse geological conditions.
Highland Regions
Areas: Central Kenya, Mount Kenya, Aberdares
Volcanic geology with excellent water availability. High rainfall provides good aquifer recharge.
- Typical drilling depth: 100–150m
- Average yield: 6–40 m³/day
- Water quality: Excellent (low TDS)
Arid & Semi-Arid Regions
Areas: Turkana, Samburu, Kajiado, Isiolo
Challenging geology with deep aquifers and low recharge rates. Careful yield assessment critical.
- Typical drilling depth: 200–350m
- Average yield: 5–15 m³/day
- Water quality: Variable (higher TDS)
Cost Analysis: Survey Investment vs. Drilling Disaster
A hydrogeological survey costs KES 35,000 and takes 1–3 days. This is a fraction of drilling costs and protects you from far more expensive failures.
With Professional Survey
Survey Cost: KES 35,000
Drilling Cost: KES 400,000–1,800,000
- 99% chance of successful water discovery
- Accurate cost projections prevent budget shocks
- Optimal location minimizes complications
- Water quality assessed upfront
- Long-term sustainability assured
Total: KES 435,000–1,835,000
Without Survey (High Risk)
Survey Cost: KES 0 (skipped)
Drilling Cost: KES 600,000–2,000,000+
- 20–30% chance of dry borehole
- No cost certainty — may exceed 50–100%
- Possible poor water quality discovered too late
- Risk of aquifer depletion
- No recourse if borehole fails
Potential Loss: KES 500,000–1,000,000+
The Clear Choice
