Cost of Drilling a Borehole in Nigeria
Access to clean water remains a challenge in many parts of Nigeria, with unreliable public water supply forcing individuals and businesses to seek alternative sources. Boreholes have become a popular solution, providing consistent and clean water for residential, commercial, and industrial use.
However, drilling a borehole requires careful planning and a significant financial commitment.
The cost of drilling a borehole in Nigeria varies based on several factors, including location, depth, materials used, and additional components like water pumps and purification systems.
This article provides a comprehensive breakdown of the costs associated with borehole drilling in Nigeria, helping you make informed decisions when planning your water supply project.
Factors Affecting the Cost of Drilling a Borehole in Nigeria
Several key factors influence how much it will cost to drill a borehole in Nigeria:
1. Location & Geology
The geographical location plays a crucial role in determining the cost of drilling a borehole. The soil and rock formation in different areas affect the drilling difficulty and cost. For example:
- Lagos and coastal areas: Sandy and soft soil may require specialized drilling techniques, increasing costs.
- Northern Nigeria: Rocky terrain makes drilling more expensive due to the need for heavy-duty drilling rigs and additional time.
- South-East and South-South regions: High water tables in these regions may reduce drilling depth, making it relatively cheaper.
2. Borehole Depth
The depth of the borehole is one of the most significant cost factors. Boreholes can be classified into:
- Shallow boreholes (less than 50m): Suitable for areas with a high water table and less expensive.
- Medium-depth boreholes (50m – 100m): Common for residential use.
- Deep boreholes (100m – 200m and above): Necessary for areas with deep water tables, making them costlier due to increased drilling time and material usage.
3. Drilling Method
There are two main drilling methods:
- Manual Drilling: Involves using hand-operated equipment and is only feasible for shallow boreholes (under 50m). It is cheaper but may not be reliable for long-term water supply.
- Machine Drilling: Uses modern drilling rigs and is more expensive but necessary for deeper boreholes. Machine drilling ensures durability and a higher water yield.
4. Casing and Piping Materials
The casing is an essential part of borehole construction, preventing soil collapse and maintaining water flow. Different materials come at different costs:
- PVC pipes: Common and affordable, suitable for shallow and medium-depth boreholes.
- Galvanized steel pipes: More expensive but highly durable, recommended for deep boreholes.
- Stainless steel pipes: The most expensive option, used for high-quality and long-lasting installations.
5. Water Pump Type
The type of water pump used affects the overall cost. There are three main types:
- Hand pumps: Suitable for low-budget projects but require manual effort.
- Electric pumps: Common in homes and businesses, running on the national grid or generators.
- Solar-powered pumps: Expensive upfront but cost-effective in the long run, especially in areas with unreliable electricity.
6. Additional Costs
Other expenses that influence the total borehole cost include:
- Water testing and treatment: Ensures safe drinking water and may require filtration or chemical treatment.
- Borehole maintenance: Regular servicing is necessary to prevent clogging and ensure longevity.
- Power source: In areas with erratic power supply, a backup generator or solar inverter system may be needed for electric pumps.

- Machine drilling: ₦500,000 – ₦3,000,000 (varies by depth and region)
How to Reduce Borehole Drilling Costs
Drilling a borehole can be expensive, but here are ways to reduce costs without compromising quality:
1. Get Multiple Quotes
Consult multiple drilling companies to compare prices and services. Ensure that all costs (including casing, pumping system, and installation) are included in the quotes.
2. Choose the Right Drilling Method
Opt for manual drilling only if the borehole depth is shallow and suitable for your water needs. Machine drilling is ideal for deep and durable boreholes.
3. Conduct a Proper Site Survey
A professional site survey helps determine the best location for drilling, reducing the risk of dry boreholes or excessive depth drilling.
4. Use Quality Materials
Invest in high-quality casing and pumps to avoid frequent repairs and long-term maintenance costs.
5. Consider Solar-Powered Pumps
If you live in an area with unreliable electricity, a solar-powered water pump can reduce energy costs in the long run.
