Krugersdorp sits on the West Rand dolomite belt alongside Witwatersrand rocks, with a long mining history behind it.
High yields are possible on the dolomite, and both ground stability and water quality need proper attention.
What Is Under Krugersdorp
The formations below are what a rig actually meets on a Krugersdorp property, and between them they govern the depth, the casing requirement and what the hole will realistically give you.
| Formation | Where it sits | What it means for drilling |
|---|---|---|
| Malmani Subgroup dolomite | The karst bedrock beneath much of the area | Capable of very high yields where solution cavities are intersected, and the most stability-sensitive ground to drill in the country. |
| Chert residuum and wad | The weathered blanket above the dolomite | Compressible, low-density material. Uncontrolled water movement through it is the mechanism behind sinkhole formation, which the West Rand has a long documented history of. |
| Witwatersrand quartzite | Flanking the dolomite belt | Hard fractured rock with moderate, fracture-dependent yields, and a different drilling proposition entirely. |

- Ground stability comes before yield here. A site stability assessment precedes drilling on dolomite, and that sequence is not negotiable.
- Yields swing wildly between compartments, so a neighbour's result tells you little about your own.
- Mining dewatering has affected water levels across parts of this belt, which is worth establishing locally before committing to a project.

What to Watch For Here
The West Rand has a long documented sinkhole history. Dolomite protocol - stability assessment, correct casing and sealing, controlled water handling - is a safety requirement here rather than a formality.
Mining dewatering and acid mine drainage have both affected groundwater on parts of the West Rand, which makes the analysis the first step.
What the Water Is Used For
- Stock watering and animal supply
- Orchard, vegetable and pasture irrigation
- Stable, shed and equipment washdown
- Household supply where the analysis allows it
- Fire water and standby storage
Wellpoint or Borehole?
No. Dolomitic karst is entirely unsuited to a driven point, and shallow abstraction on this ground raises exactly the stability questions you want to avoid.
Water Quality in Krugersdorp
Dolomitic water is hard, which scales geysers and fittings over time and is straightforward to treat. The more significant question on the West Rand is mining impact - sulphate, metals and acid mine drainage have affected groundwater in parts of the belt, and a full analysis is the right starting point.
A water analysis is what turns that from a general expectation into a number for your specific hole, and treatment should be specified against the result rather than against the area's reputation.
Registration and Abstraction
Registration sits with the local municipality, and on the West Rand the dolomitic ground carries additional geotechnical expectations. The National Water Act applies on top: reasonable domestic use generally falls under Schedule 1, while irrigation or commercial abstraction may require registration or a water use authorisation from the Department of Water and Sanitation. Requirements change, so confirm your position before drilling.

Borehole Prices in Krugersdorp
Drilling is charged per metre, so depth drives the total. The ranges below are framed for local ground conditions and access.
| Item | Indicative range | What moves it locally |
|---|---|---|
| Drilling, per metre | R500 - R1,100 /m | Dolomite drills reasonably but cavities complicate the hole and dolomite protocol adds cost. |
| uPVC casing, installed, per metre | R450 - R850 /m | Casing and sealing through the residuum is a ground-stability requirement here. |
| Mobilisation and site establishment | R3,500 - R12,000 | Access and site conditions move this; a site visit settles it before quoting. |
| Water survey | R5,000 - R12,000 | Targets structure rather than depth. Worth most where yield is fracture-dependent. |
| Yield testing | R3,500 - R15,000 | Establishes the sustainable rate that pump selection depends on. |
| Pump, supplied and installed | R15,000 - R45,000 | Greater depth means more head, which means a larger pump and heavier cable. |
| Storage and booster | R12,000 - R35,000 | Needed wherever peak demand exceeds the borehole's sustainable rate. |
| Typical complete project | R90,000 - R240,000+ | Everything above, excluding treatment, which depends entirely on the water analysis. |
These are indicative ranges, not a quotation. They are compiled from published South African supplier and contractor pricing to give you a starting point for budgeting. They are not our rate card, and no figure here is a commitment.
Treat them as a broad guide only. Published borehole pricing in South Africa varies enormously - different 2026 guides quote per-metre drilling rates for the same province that differ by a factor of three - because depth, geology, access, specification, distance and fuel costs all move the number. Depth in particular is not known until the hole is finished. Figures generally exclude VAT unless noted, and change over time. Only an itemised written quote against your actual site means anything.
Krugersdorp Borehole FAQs
How serious is the sinkhole risk in Krugersdorp?
Serious enough that it governs how drilling is done. The West Rand dolomite belt has a long documented history of subsidence, and uncontrolled water movement through compressible residuum is the mechanism.
A site stability assessment before drilling, proper casing and sealing, and controlled handling of drilling water are what manage it. A quote that does not mention any of this is worth questioning.
Is Krugersdorp groundwater affected by mining?
In places. Mining dewatering has affected water levels across parts of the belt and acid mine drainage is documented on the West Rand.
That does not rule out a borehole. It does mean a full laboratory analysis is the right starting point rather than an optional extra.
Is drilling on dolomite in Krugersdorp risky?
It carries real risk if it is done carelessly, which is why dolomite protocol exists. Uncontrolled water loss into compressible residuum is the mechanism that forms sinkholes, and the West Rand has a long documented history of them.
Done properly - stability assessment first, correct casing and sealing, no uncontrolled water loss - it is a managed risk. The contractor's approach to this matters more than their per-metre rate.
Why is the water so hard in Krugersdorp?
Dolomite is calcium magnesium carbonate, and groundwater moving through it dissolves both. Hard water is the normal and expected result on this ground.
It scales kettles, geysers and irrigation fittings over time. Softening is routine treatment once an analysis quantifies the hardness.
