With increasing water shortages in many parts of Kenya, borehole drilling has become a reliable solution for homes, farms, institutions, and businesses. A borehole provides a consistent and independent water supply, making it a valuable long-term investment.
At NICS Hardware and Borehole Services, we offer professional borehole drilling services across Kenya. This guide explains the entire process step by step.
Hydrogeological Survey
Before drilling begins, a hydrogeological survey is conducted.
Purpose:
- Identify underground water sources
- Determine drilling location
- Estimate water yield
Methods:
- Geological mapping
- Geophysical surveys
Site Selection and Approval
Once a suitable location is identified, approvals are required.
Requirements:
- Permits from relevant authorities (e.g., WRA)
- Environmental considerations
Mobilization of Equipment
Drilling equipment is transported to the site.
Equipment Includes:
- Drilling rig
- Water tankers
- Support machinery
Drilling the Borehole
Drilling is carried out to reach the aquifer.
Process:
- Drilling through soil and rock layers
- Reaching water-bearing zones
Depth:
Typically ranges from 50m to 300m depending on location.
Casing Installation
Casing pipes are installed to support the borehole walls.
Materials:
- PVC or steel casing
Purpose:
- Prevent collapse
- Protect water from contamination
Gravel Packing
Gravel is placed around the casing.
Function:
- Filters water
- Prevents sand entry
Well Development
The borehole is cleaned and tested.
Methods:
- Airlifting
- Pumping
Pump Installation
A suitable pump is installed.
Types:
- Submersible pumps
- Solar-powered pumps
Water Testing
Water quality is tested for safety.
Tests Include:
- Chemical analysis
- Bacteriological analysis
Borehole Completion
Final touches include:
- Installing a well cover
- Connecting water systems
Benefits of Borehole Drilling
- Reliable water supply
- Reduced water bills
- Increased property value
Conclusion
Borehole drilling is a smart investment for anyone seeking water independence in Kenya. Understanding the process helps you make informed decisions and ensures a successful project.
