Borehole Cost Calculator Nigeria: How Much Does a Borehole Cost in 2026?

In a country where public water supply is unreliable in almost every state, a borehole is not a luxury — it is a necessity for most Nigerian properties above subsistence level. Residential homes, commercial buildings, industrial facilities, schools, hospitals, and estate developments all depend on privately drilled boreholes for water supply. Yet borehole pricing is one of the most opaque parts of the Nigerian construction market, with quotes varying by 200% to 400% for seemingly similar jobs depending on location, driller, and market conditions.

Our free Borehole Cost Calculator demystifies borehole pricing in Nigeria, providing a clear, item-by-item estimate for drilling, casing, pumping equipment, overhead tank, and electrical connection — all calibrated to 2026 market rates by region.

What Determines Borehole Cost in Nigeria?

1. Target Depth

This is the single largest variable in borehole pricing. Borehole depth varies by geological formation and location:

• Lagos coastal plain: 30m to 80m to reach a productive aquifer in most areas. Some locations in Lekki and Ikoyi require 100m+ for good quality water.
• Abuja / FCT: Basement rock geology means water is found in fractured rock at depths of 40m to 120m. Some sites in Abuja require 150m+ drilling.
• Port Harcourt / Rivers State: Shallow aquifers often at 20m to 50m due to the river delta geology, but water quality can be problematic (iron-rich or brackish at shallow depths).
• Southwest Nigeria (Ibadan, Abeokuta): 30m to 80m typically, with basement rock encountered in some areas.
• Northern Nigeria (Kano, Kaduna, Jos): Highly variable — 30m to 200m+ depending on location. Jos Plateau requires very deep drilling to reach water below the fractured rock.

2. Borehole Diameter

Standard residential boreholes in Nigeria are typically drilled at 6 inches (150mm) diameter, providing enough space for a 4-inch submersible pump. Larger commercial or industrial boreholes (8 inch or 10 inch diameter) allow higher yield pumps and greater water production but cost significantly more per metre of drilling.

3. Casing Type and Length

The borehole must be lined (cased) from the surface down to the aquifer entry point to prevent collapse and surface water contamination. Two main casing types:

• uPVC casing: Standard for most Nigerian residential boreholes. Cheaper, non-corrosive, widely available. Appropriate for depths to approximately 80m.
• Steel casing: Required for deeper boreholes and rock drilling. More expensive but necessary for structural integrity in deep basement rock formations.

4. Pump Type and Specification

The pump selection depends on static water level (the depth at which water stabilises in the casing after drilling) and required flow rate. Two main pump types:

• Submersible pump: The standard for Nigerian boreholes. The pump unit is lowered into the borehole on a discharge pipe, connected to the power supply by a submersible cable. Submersible pumps are quiet, efficient, and reliable. Brands commonly used in Nigeria include Grundfos, Pedrollo, DAB, and locally-sourced Chinese brands. Quality varies enormously — always specify brand and model.
• Surface suction pump: Only suitable for boreholes where static water level is within 7m to 8m of surface (rare in most Nigerian locations). Cheaper than submersible but limited in application.

5. Overhead Tank

Most Nigerian borehole installations include an overhead tank (typically 1,000 to 5,000 litres capacity) to store pumped water and provide gravity feed to the building. Tank size, material (PVC, polyethylene, or galvanised steel) and tank stand height all affect cost. Our calculator includes tank and stand sizing based on number of building occupants and desired days of storage.

6. Electrical Connection and Control Panel

A borehole pump requires a dedicated electrical connection from the main distribution board, typically on a separate circuit with appropriate cable sizing. An automatic pump controller (level switch or pressure switch) prevents the pump running dry and enables automatic filling of the overhead tank. This electrical work is often quoted separately by the driller and needs to be included in the total budget.

Typical Borehole Costs in Nigeria (2026)

• Drilling (per metre, 6-inch uPVC casing, Lagos/SW Nigeria): ₦35,000 – ₦60,000
• Drilling (per metre, 6-inch, Abuja rock formation): ₦55,000 – ₦90,000
• uPVC casing supply and installation: Typically included in drilling rate above
• Submersible pump (0.75kW, quality brand, 60m head): ₦180,000 – ₦350,000
• Pump installation (cable, pipe, fitting): ₦45,000 – ₦90,000
• 1,000L polyethylene overhead tank + 3m steel stand: ₦120,000 – ₦200,000
• 2,000L polyethylene overhead tank + 4m steel stand: ₦200,000 – ₦320,000
• Electrical connection and automatic controller: ₦60,000 – ₦120,000

Example total: residential borehole, 60m depth, Lagos:

• Drilling (60m × ₦45,000): ₦2,700,000
• Submersible pump and installation: ₦380,000
• 2,000L tank + stand: ₦280,000
• Electrical + controller: ₦90,000
• Total: approximately ₦3,450,000

Frequently Asked Questions

How long does a borehole last in Nigeria?

A properly drilled and cased borehole with a quality submersible pump can last 20 to 30+ years with regular maintenance. The pump is the component most likely to require replacement (typical submersible pump life: 5 to 10 years depending on usage, water quality, and brand). Casing lasts the life of the borehole.

Do I need a permit to drill a borehole in Nigeria?

Yes. Most Nigerian states require a borehole permit from the state water agency or ministry of water resources. In the FCT, permits are issued by the FCT Water Board. In practice, enforcement is inconsistent, but drilling without a permit creates title risk and may affect property sale in future.

How do I know if my borehole water is safe to drink?

Always commission a water quality test from a certified laboratory before using borehole water for drinking or cooking. Common contaminants in Nigerian borehole water include iron, total dissolved solids, coliform bacteria (contamination from surface seepage), and in some areas, nitrates. Treatment (filtration and UV sterilisation) may be required depending on test results.
