Installing a borehole at home has become increasingly popular in South Africa as water restrictions, municipal supply issues, and rising utility costs push homeowners to look for reliable alternatives.
A properly installed borehole can provide independent access to groundwater, reducing dependence on municipal water and potentially saving thousands of rand over time.
However, one of the most common questions homeowners ask is:
“What is the total cost of installing a borehole at home?”
The short answer is that the total cost typically ranges between R60,000 and R120,000+, depending on drilling depth, equipment, pump systems, and water treatment requirements.
In this guide, we’ll break down every cost involved so you can understand exactly what to expect when installing a borehole on your property in South Africa.
Average Total Cost of Installing a Borehole at Home
The total installation cost usually includes several components:
| Component | Typical Cost Range |
| Borehole drilling | R300 – R500 per meter |
| Borehole casing | R400 – R800 per meter |
| Pump installation | R10,000 – R25,000 |
| Electrical installation | R3,000 – R10,000 |
| Water storage tank | R3,000 – R15,000 |
| Filtration system | R2,000 – R10,000 |
Estimated Total Cost
Most homeowners spend:
R60,000 – R120,000 for a complete borehole system.
If drilling must go very deep or specialized equipment is needed, costs can exceed R150,000.
Cost Breakdown of Borehole Installation
Understanding where your money goes helps you plan the installation properly.
Let’s look at each cost component in detail.
1. Borehole Drilling Costs
Drilling is the largest part of the overall expense.
In South Africa, drilling companies usually charge per meter drilled.
Typical drilling prices:
- R300 – R500 per meter
If a borehole needs to reach 60 meters, drilling alone may cost:
- R18,000 – R30,000
However, in areas with deeper aquifers, drilling may reach 100 meters or more.
Factors that influence drilling cost
- Geological conditions
- Rock hardness
- Borehole depth
- Location accessibility
- Equipment required
2. Borehole Casing Costs
After drilling, the borehole must be lined with casing to prevent collapse and contamination.
Casing typically costs:
- R400 – R800 per meter
Common casing materials:
- PVC casing
- Steel casing
PVC is usually more affordable and corrosion-resistant, while steel is stronger but more expensive.
3. Borehole Pump Installation Costs
Once the borehole reaches water, a pump system must be installed to extract water.
Pump installation costs range from:
R10,000 – R25,000
This includes:
- Submersible pump
- Pump cables
- Control box
- Installation labour
The exact price depends on:
- Borehole depth
- Pump power
- Water yield

4. Electrical Installation
Most borehole pumps require electrical connections.
Typical electrical costs include:
- Wiring
- Pump control box
- Electrical protection systems
Estimated cost:
R3,000 – R10,000
In some cases, homeowners install solar-powered borehole pumps, which increases initial cost but reduces long-term electricity usage.
5. Water Storage Tank
Many borehole systems include storage tanks to ensure consistent water supply.
Tank sizes commonly used in homes:
- 2500L
- 5000L
- 10,000L
Estimated cost:
R3,000 – R15,000
Larger tanks are recommended for properties that rely completely on borehole water.
6. Water Filtration Systems
Borehole water may contain minerals or sediments that require treatment.
Common filtration systems include:
- Sediment filters
- Carbon filters
- Iron removal systems
- UV purification systems
Typical cost:
R2,000 – R10,000
Not all boreholes require extensive filtration, but water testing is strongly recommended.
Hidden Costs Homeowners Often Forget
Many homeowners underestimate the total installation cost because they overlook smaller expenses.
These may include:
- Geological surveys
- Borehole testing
- Pump protection equipment
- Trenching and piping
- System maintenance
These additional costs may add R5,000 – R20,000 to the project.
Factors That Affect Borehole Installation Cost
Several factors influence the final price.
1. Borehole Depth
The deeper the borehole, the higher the drilling cost.
Typical residential boreholes range from:
- 40m – 120m
2. Geological Conditions
Hard rock formations increase drilling difficulty and cost.
Areas with fractured rock aquifers may require deeper drilling.
3. Pump Size and Power
Higher water demand requires larger pumps.
Homes with gardens, pools, or irrigation systems may need stronger pumps.
4. Water Yield
Higher yielding boreholes may require larger pumps and storage tanks.
Low-yield boreholes sometimes need additional drilling.
Example Borehole Installation Cost
Here is a realistic example of a typical installation.
| Component | Cost |
| Drilling (70m) | R28,000 |
| Borehole casing | R15,000 |
| Pump system | R18,000 |
| Electrical installation | R6,000 |
| Water tank | R5,000 |
| Filtration system | R4,000 |
Total Installation Cost
Approximately R76,000
Is Installing a Borehole Worth It?
Despite the upfront cost, many homeowners find boreholes extremely valuable.
Benefits include:
- Reliable water supply
- Reduced municipal water bills
- Water independence during restrictions
- Increased property value
In many cases, boreholes pay for themselves over time, especially in areas with high water tariffs.
How Long Does Borehole Installation Take?
A typical residential borehole installation takes 2–5 days.
Steps include:
- Site inspection
- Borehole drilling
- Pump installation
- Electrical connection
- Water testing
However, drilling may take longer if geological conditions are challenging.
Tips for Reducing Borehole Installation Costs
Homeowners can reduce installation costs by:
- Comparing drilling contractors
- Testing groundwater potential first
- Installing correctly sized pumps
- Avoiding unnecessary equipment
Working with experienced drilling companies can also prevent costly mistakes.
Frequently Asked Questions

Yes, especially during drought conditions or if the borehole is poorly positioned.
Final Thoughts
The total cost of installing a borehole at home in South Africa typically ranges between R60,000 and R120,000, depending on drilling depth, pump systems, and additional equipment.
While the upfront cost may seem significant, a borehole offers long-term water security, independence from municipal supply, and potential savings on water bills.
