What is Borehole Drilling?
Borehole drilling is the process of drilling deep underground to access water stored in aquifers beneath rocks and soil layers.
The borehole is lined using casing pipes to prevent collapse and contamination. A pump is then installed to draw water to the surface.
In Machakos County, boreholes are important because rainfall is unreliable and many rivers dry up during long drought seasons.
Why Borehole Drilling in Machakos is Important
Machakos experiences semi-arid weather conditions. Rainfall is low and uneven in many areas such as Kathiani, Mwala, Yatta, Masinga, and Kangundo.
Because of this, many residents depend on:
- Water bowsers
- Seasonal rivers
- Water pans
- Community dams
- Municipal water supply
These sources are often unreliable during dry seasons.
Borehole Drilling in Machakos 2026 helps solve water shortages by providing a steady water supply throughout the year.
Main Benefits of Boreholes in Machakos
- Reliable water supply
- Reduced water bills
- Water for irrigation farming
- Better livestock management
- Increased property value
- Water independence
- Reduced drought effects
- Long-term investment
Weather Patterns in Machakos and Their Impact on Boreholes
Machakos County has hot and dry weather for most months of the year.
Rainfall Patterns
| Season | Rainfall Level |
|---|---|
| March – May | Moderate rains |
