Drilling a borehole in Kenya can provide a long-term, independent water supply for homes, farms, factories, and institutions. However, the process requires planning, permits, and the right contractors to ensure the borehole is legal, sustainable, and high-yielding.
This step-by-step guide explains the borehole drilling process in Kenya, including permits, costs, and best practices so you can confidently invest in your water project.
Step 1: Conduct a Hydrogeological Survey
Before drilling, you must hire a licensed hydrogeologist to conduct a hydrogeological survey.
This survey:
- Determines whether groundwater exists at your site
- Identifies the depth and quality of the water
- Recommends the best drilling location
- Is a legal requirement for WRA permit/ approval
Cost: Hydrogeological surveys in Kenya range from KSh 50,000 to KSh 150,000, depending on location and complexity.
Step 2: Apply for a Borehole Drilling Permit
You must obtain approval from the Water Resources Authority (WRA) before drilling.
The WRA application requires:
- Hydrogeological survey report
- Land ownership documents (title deed or lease)
- National ID copy
- Completed WRA application forms
- Payment of application fees
Processing Time: 2–4 weeks, depending on workload and documentation.
Tip: Your borehole drilling company or hydrogeologist can handle the application on your behalf.
Step 3: Get Environmental Approval from NEMA
The National Environment Management Authority (NEMA) must assess your project to ensure it does not harm the environment.
This involves:
- Environmental Impact Assessment (EIA)
- Site inspection
- Public consultation (for large projects)
Cost: KSh 30,000–KSh 70,000 for most small to medium boreholes.
Step 4: Select a Licensed Borehole Drilling Company
Once permits are approved, choose a licensed borehole drilling contractor in Kenya with:
- Valid WRA and NEMA licenses
- Experience in your county’s geology
- Modern drilling rigs and equipment
- Clear contracts and transparent pricing

Step 5: Drilling the Borehole
The drilling process typically includes:
- Mobilization – Moving rigs, compressors, and support vehicles to the site.
- Drilling – Using rotary or percussion methods depending on geology.
- Casing Installation – PVC or steel pipes inserted to keep borehole walls stable.
- Gravel Packing – Prevents fine particles from entering the borehole.
- Sanitary Sealing – Protects water from contamination.
Timeline: 3–7 days depending on depth and soil type.
Step 6: Pump Installation (Equipping) and Water Testing
After drilling, the borehole is fitted with a submersible pump or solar pump.
You should also:
- Test the water for fluoride, salinity, and bacteria as per the KS EAS 12:2018 specifications for portable water https://webstore.kebs.org/index.php?route=product/product&product_id=14909 and guidelines for drinking water quality of WHO 4th Edition https://www.who.int/publications/i/item/9789241549950
- Install filtration or treatment if necessary
- Build water storage tanks for distribution
Cost of Pump and accessories: KSh 200,000–KSh 800,000 depending on type and capacity.
Step 7: Registration and Maintenance
Once complete, register your borehole with WRA and schedule routine maintenance.
Maintenance includes:
- Pump servicing
- Borehole cleaning every 2–3 years
- Regular water quality checks
Typical Borehole Drilling Costs in Kenya (2025)
| Stage | Estimated Cost (KSh) |
| Hydrogeological Survey | 50,000 – 100,000 |
| WRA & NEMA Permits | 30,000 – 100,000 |
| Drilling (per meter) | 6,500 – 8,500 |
| Pump Installation (Equipping) | 200,000 – 800,000 |
💡 Note: Costs vary by county, geology, and depth.
Frequently Asked Questions about Borehole Drilling in Kenya
Q1: How long does it take to drill a borehole in Kenya?
Typically 1–2 months from survey to completion, depending on permits and drilling conditions.
Q2: Can I drill without WRA and NEMA permits?
No. It is illegal and may result in fines or borehole closure.
Q3: How deep should a borehole be in Kenya?
Usually 70–250 meters depending on water table levels.
Conclusion
The borehole drilling process in Kenya involves several legal, technical, and environmental steps. By following this guide — from hydrogeological survey to final pump installation — you can ensure your borehole is legal, efficient, and long-lasting.
