Access to clean and reliable water is essential for households, businesses, and industries in Nigeria. One of the best ways to ensure a steady water supply is by drilling a borehole. However, understanding the cost of borehole drilling in Nigeria is crucial before starting the process.
This guide provides a detailed quotation for borehole drilling in Nigeria, covering factors affecting costs, price estimates, and key considerations for hiring a drilling company.
Factors Affecting Borehole Drilling Costs in Nigeria
The cost of drilling a borehole in Nigeria depends on several factors, including:
1. Location of the Site
- Areas with soft soil require less drilling effort, making the process cheaper.
- Hard rock formations or deep drilling areas increase labor and equipment costs.
- Urban areas may have higher charges due to logistics and accessibility.
2. Depth of the Borehole
- A shallow borehole (30-50 meters) is cheaper than a deep borehole (100+ meters).
- Water table depth varies by region, affecting how deep drilling is required.
3. Type of Borehole
- Manual drilling is more affordable but suitable for shallow wells.
- Machine drilling is necessary for deep boreholes, increasing costs.
4. Casing Material Used
- PVC casing is cheaper but may not last as long as steel casing.
- Stainless steel casing is more durable but costs significantly more.
5. Pump Type and Installation
- Hand pumps are the cheapest option.
- Electric and solar-powered pumps are more expensive but provide efficient water flow.
6. Water Treatment and Filtration
- In areas with high iron or salt content, water treatment systems are needed.
- Additional filtration increases the total cost of borehole installation.
Estimated Cost of Borehole Drilling in Nigeria

| Item | Estimated Cost (₦) | Estimated Cost (USD) |
|---|---|---|
| Site Survey | 30,000 – 100,000 | $40 – $120 |
| Drilling (per meter) | 10,000 – 25,000 | $13 – $32 |
| PVC Casing (per meter) | 5,000 – 12,000 | $6 – $15 |
| Steel Casing (per meter) | 20,000 – 40,000 | $25 – $50 |
| Submersible Pump | 100,000 – 500,000 | $130 – $650 |
| Hand Pump | 50,000 – 150,000 | $65 – $195 |
| Water Filtration | 50,000 – 300,000 | $65 – $390 |
| Plumbing & Piping | 50,000 – 250,000 | $65 – $325 |
| Total Estimated Cost | 500,000 – 3,000,000 | $650 – $3,900 |
Notes:
- Costs vary based on region, borehole depth, and materials used.
- Manual drilling is cheaper but not suitable for all locations.
- Deep boreholes require more casing and pumping power, increasing expenses.
Steps Involved in Borehole Drilling
1. Site Survey and Feasibility Study
A professional survey is conducted to determine:
- Best location for drilling
- Expected water table depth
- Soil and rock conditions
2. Drilling Process
- A rig machine or manual drilling method is used.
- Drilling continues until sufficient water is found.
- The depth of the borehole depends on the water table and rock formation.
3. Casing Installation
- A casing is inserted to prevent borehole collapse.
- PVC casing is common for household boreholes, while steel casing is used for industrial boreholes.
4. Pump Installation
- A submersible pump or hand pump is installed.
- Solar pumps are ideal for off-grid locations.
5. Water Testing and Filtration
- Water is tested for quality and safety.
- Filtration systems may be added if contaminants are found.
6. Plumbing and Final Setup
- Pipes are connected to the main water system.
- The borehole is sealed and protected from contaminants.
Choosing the Right Borehole Drilling Company
1. Experience and Reputation
- Work with licensed and experienced drilling companies.
- Check customer reviews and project history.
2. Equipment and Technology
- Ensure the company has modern drilling rigs and testing tools.
- Machine drilling provides faster and deeper drilling capabilities.
3. Pricing and Transparency
- Get multiple quotations from different drilling companies.
- Ensure there are no hidden fees in the pricing structure.
4. After-Sales Services
- Choose a company that offers maintenance, repairs, and warranty.
- Regular servicing ensures longevity and efficiency.
Common Borehole Drilling Challenges in Nigeria
1. Unstable Soil Conditions
- Some regions have loose soil that collapses easily, requiring additional casing.
2. Water Table Variations
- In some areas, water levels fluctuate, making deep drilling necessary.
3. Power Supply Issues
- Electric pumps require a stable power source.
- Solar pumps are a good alternative but cost more upfront.
4. Seasonal Water Scarcity
- Boreholes may dry up during dry seasons, especially if not drilled deep enough.
5. Poor-Quality Drilling Services
- Some drilling companies cut corners, leading to low water yield or borehole failure.
Benefits of Drilling a Borehole in Nigeria
- Independence from unreliable public water supply
- Cost savings on water bills
- Consistent water access for homes, farms, and businesses
- Increased property value
- Improved water quality and sanitation
Drilling a borehole in Nigeria is a long-term investment that provides reliable water access. The cost depends on location, depth, casing materials, and pump type. A typical borehole costs between ₦500,000 and ₦3,000,000 ($650 – $3,900), depending on the specifications.
To ensure a successful borehole project, choose a reputable drilling company, get a detailed quotation, and consider future maintenance costs.
