With municipal water tariffs rising and supply becoming increasingly unreliable across the country, more South African homeowners are turning to boreholes as a long-term water security solution. But one question dominates every conversation: how much does it actually cost?
The short answer is that borehole drilling in South Africa typically costs between R20,000 and R60,000 for drilling alone, while a complete system installation ranges from R60,000 to R120,000 or more. However, the final price depends on many factors unique to your property.
This guide breaks down every cost component, explains why prices vary so dramatically by province, and gives you the tools to budget accurately for your borehole project.
Borehole Drilling Price In South Africa
For a typical 60-metre domestic borehole in Gauteng with a submersible pump and basic testing, you can expect to pay approximately R51,300.
Drilling Costs By Province
Your location is one of the biggest determinants of price. Different provinces have different geological conditions, water table depths, and levels of contractor competition.
Estimated Drilling Cost Per Metre (60m Borehole Reference)
| Province | Cost Per Metre | Drilling Cost (60m) |
|---|---|---|
| Free State | R310/m | R18,600 |
| Limpopo | R320/m | R19,200 |
| North West | R320/m | R19,200 |
| Mpumalanga | R330/m | R19,800 |
| Eastern Cape | R340/m | R20,400 |
| KwaZulu-Natal | R350/m | R21,000 |
| Northern Cape | R350/m | R21,000 |
| Gauteng | R380/m | R22,800 |
| Western Cape | R420/m | R25,200 |
Why Prices Vary So Much By Province
Gauteng often involves hard rock formations and dolomite zones, which increase drilling time and complexity. The recent incident where a borehole was drilled into the Gautrain tunnel has also led to stricter consent processes and temporary industry slowdowns.
Western Cape has some of the highest costs due to challenging geology and high demand following the severe drought in previous years.
Free State and Northern Cape typically require deeper drilling, with water tables often past 100 metres. While the per-metre rate may be lower, the total cost is higher because of the extra depth.
KZN and Eastern Cape generally have softer sediments but higher water table variability, making yield unpredictable.
In provinces where drilling companies are scarce, like the Northern Cape, drill rigs must travel long distances, increasing transport and mobilisation fees.
Factors That Affect Borehole Drilling Cost
1. Depth
This is the single biggest factor. Drilling is charged per metre, and the deeper you go, the more you pay. Most domestic boreholes in South Africa are drilled to between 30 metres and 100 metres. In some areas, water is found at 20 metres; in others, you may need to go beyond 150 metres.
2. Ground Conditions (Geology)
Hard rock formations like granite and dolerite are slower and more expensive to drill through than softer materials like sandstone or clay. If your property sits on challenging geology, expect higher costs and longer drilling times.
3. Location and Site Access
The drilling rig needs to reach your property. If access is difficult, if the ground is steep, or if the site is remote, mobilisation fees increase. Some contractors charge a flat mobilisation fee (typically R3,500 to R5,000) to transport the rig to your site.
4. Water Yield (No Guarantee)
Here is the reality that many homeowners find difficult to accept: there is no guarantee of water. If the borehole is dry, you still pay for the drilling. This is why a geological survey before drilling (costing R3,000 to R8,000) is highly recommended to reduce the risk.
Once drilling is complete, a yield test (R4,500 to R5,000) confirms how much water the borehole actually produces.
5. Casing
In unstable ground, steel or PVC casing prevents the borehole from collapsing. Not all boreholes need casing, but when required, it adds R180 to R280 per metre. Total casing costs typically range from R5,000 to R25,000 depending on depth and material.
6. Pump Type
Your pump choice dramatically affects total cost:
| Pump Type | Cost Range | Best For |
|---|---|---|
| Standard Submersible Pump | R6,000 – R25,000 | Most domestic applications, reliable water delivery |
| Solar Borehole Pump | R12,000 – R40,000+ | Off‑grid properties, sustainable pumping without electricity bills |
| Pressure Pump & Controller | R1,200 – R6,000 | Boosting water pressure to household systems |
Most homeowners choose a standard submersible pump as it offers the best balance of reliability and cost.
7. Testing
Two tests are essential after drilling:
Yield Test (R4,500 – R5,000): Confirms how many litres per hour the borehole produces.
Water Quality Test (R2,500 – R3,000): Ensures the water is safe for drinking.
8. Storage Tanks
Most homeowners add a tank system to store water for when it is needed.
| Tank Size | Approximate Cost |
|---|---|
| 2,500L tank | R2,000 – R5,000 |
| 5,000L tank | R4,000 – R7,500 |
| 10,000L tank | R8,000 – R15,000 |
| Tank stand or concrete slab | R1,500 – R4,000 |
9. Filtration and Purification
Borehole water is often high quality, but filtration is recommended for household use, especially drinking water.
| Filtration Type | Cost |
|---|---|
| Basic sediment filter | R1,200 – R2,500 |
| Iron/Manganese removal system | R3,000 – R10,000 |
| Full purification system | R6,000 – R20,000+ |
LiquaFlo builds custom purification setups based on your water quality and intended use.
Complete Cost Breakdown: A Realistic Example
Here is a realistic cost breakdown for a typical 60-metre domestic borehole in Gauteng:
| Item | Cost |
|---|---|
| Drilling (60m × R380/m) | R22,800 |
| Submersible Pump | R18,000 |
| Mobilisation (rig transport) | R3,500 |
| Yield Test | R4,500 |
| Water Quality Test | R2,500 |
| Total | R51,300 |
For a more comprehensive system including storage and filtration, costs typically rise to between R70,000 and R120,000.
The Legal and Regulatory Side: What You Need To Know
Borehole drilling is not illegal in South Africa, but it is regulated. City bylaws safeguard municipal infrastructure, and most municipalities require a consent approval process before drilling can commence.
Following an incident where a borehole was drilled into the Gautrain tunnel, drillers have been arrested, and police officials are now demanding to see proof of consent. The Borehole Water Association of Southern Africa (BWA) is currently collaborating with the City of Johannesburg and Ekurhuleni municipalities to expedite borehole consent approvals.
Before you drill, ensure your contractor:
– Is a member of the BWA (or works to SABS SANS 10299-:2003 standards)
– Obtains the necessary municipal consent
– Conducts a proper site assessment to avoid damaging underground infrastructure
The BWA advocates for responsible and legal use of borehole water throughout Southern Africa.
Is A Borehole Worth The Investment?
Given the costs involved, many homeowners ask: is it really worth it?
With water tariffs rising consistently across municipalities, a borehole can pay for itself over time. For households with large gardens, swimming pools, or high water consumption, the savings on municipal water bills can be substantial.
Gift of the Givers founder Imtiaz Sooliman has been a vocal advocate for boreholes, stating that “every school, hospital and clinic should have a borehole as a preventative measure” against water shortages.
During water crises, borehole owners have been able to share water with their neighbours. In the KZN floods, “people opened up their boreholes and opened up their hearts to anyone in the area to come and take water.”
However, groundwater is the primary source of water for over 80% of towns in Southern Africa, and a compliant borehole allows responsible access to this precious resource.
Tips For Getting The Best Price
1. Get At Least Three Quotes
Prices vary significantly between contractors. Always get multiple quotes from registered, BWA-accredited drilling companies before committing.
2. Check What Is Included
Some quotes include only drilling; others include casing, yield testing, and pump installation. Make sure you are comparing apples with apples.
3. Do A Geological Survey First
A pre-drilling geological survey (R3,000 – R8,000) can identify the best drilling location and reduce the risk of drilling a dry hole.
4. Ask About Mobilisation Fees
If your property is remote or difficult to access, ask about mobilisation fees upfront. These can add R3,500 to R5,000 to your bill.
5. Consider A Combined Package
Many drilling companies offer package deals that include drilling, pump, tank, and installation. These can be cheaper than purchasing each component separately.
Frequently Asked Questions
How deep are most domestic boreholes in South Africa?
Most domestic boreholes are drilled to between 30 metres and 100 metres, depending on the water table in your area.
Can I drill a borehole without municipal approval?
No. Most municipalities require a consent approval process before drilling. Failure to obtain approval can result in fines and legal action.
What happens if they drill and find no water?
You still pay for the drilling. This is the risk of borehole installation. A geological survey before drilling reduces this risk.
How long does a borehole last?
A properly installed and maintained borehole can last 20 to 30 years or more. The pump typically needs replacement every 8 to 12 years.
Do I still need municipal water if I have a borehole?
Many homeowners keep their municipal connection as a backup, especially during dry periods when groundwater levels may drop.

Keep In Mind
Drilling a borehole in South Africa is a significant investment, typically costing between R20,000 and R60,000 for drilling alone and R60,000 to R120,000 for a complete system. The price depends heavily on your province, the depth required, the geology of your property, and the equipment you choose.
Gauteng and Western Cape are among the more expensive provinces, while Free State and Limpopo offer lower per-metre rates. However, deeper drilling in some areas can offset lower per-metre costs.
Before you commit, get multiple quotes from BWA-accredited contractors, obtain the necessary municipal consent, and consider a geological survey to reduce risk. A borehole is not a small expense, but for many South African homeowners, the water security and long-term savings make it a worthwhile investment.
Water is life. A compliant, responsibly drilled borehole allows you to access one of the earth’s most precious resources while protecting yourself from rising municipal costs and unreliable supply.
