What Is Borehole Drilling?
Borehole drilling is the process of drilling deep into the ground to access underground water known as groundwater.
The water is pumped using:
- Electric pumps
- Solar pumps
- Diesel systems
Boreholes provide long-term water supply for:
- Domestic use
- Irrigation
- Livestock
- Commercial buildings
- Schools
- Hotels
- Factories
Why Borehole Drilling Is Growing in Kenya
Water demand in Kenya continues to increase because of:
- Population growth
- Urban development
- Climate changes
- Water shortages
- Rising water bills
Many areas experience unreliable county water supply. This has increased demand for private boreholes.
Solar-powered boreholes are also becoming popular because they reduce electricity costs.

- Aquifer location
- Region
Borehole Casing
PVC or steel casing pipes are installed to protect the borehole walls.
Test Pumping
Water yield is tested to measure:
- Water quantity
- Recovery rate
- Sustainability
Water Quality Testing
Water is tested for:
- Salinity
- Bacteria
- Minerals
- Safety
Borehole Equipping
