Krugersdorp sits where Malmani dolomite meets the Witwatersrand. Dolomite underlies ground to the north and west toward the Cradle of Humankind, while the historic West Rand reef workings run along the south.
Suburbs like Monument, Noordheuwel and Kenmare surround the Krugersdorp Game Reserve, with smallholdings stretching toward Muldersdrift. The area is also where West Rand acid mine drainage first decanted in 2002.
What Is Under Krugersdorp
| Formation | Where it sits | What it means for drilling |
|---|---|---|
| Malmani Subgroup dolomite | North and west of the town toward the Cradle of Humankind | A karst aquifer. Water moves through cavities and fracture zones, so yields can be strong in one hole and poor nearby. |
| Chert and chert breccia | Bands in the dolomite and rubble above it | Very hard drilling that wears bits. Progress varies sharply with the chert content. |
| Wad and residual soil | The leached layer between soil and bedrock | Low-density, compressible material that must be cased. Its thickness is unknown until drilled. |

- Budget for slow metres through chert which widens the cost range.
- Casing through wad is not optional and its thickness is not known in advance.
- Loss of circulation is common when a cavity is opened.

What to Watch For Here
Dolomite brings water and stability risk together. The karst aquifer to the north and west is the strongest groundwater source in the region, yet cavities, chert and soft wad make drilling demanding. Leaking pipes and poor stormwater around a property can trigger sinkholes, so good maintenance matters. SANS 1936 considerations apply on dolomite land, and Mogale City's current requirements must be confirmed first.
AMD decant changed groundwater to the south. The West Rand basin began decanting acid mine drainage near Krugersdorp in 2002. Groundwater near the southern mining belt may be acidic and carry sulphate, iron, manganese and dissolved metals, with uranium a concern close to tailings. Test carefully before using this water for anything beyond tolerant plants.
What the Water Is Used For
- Watering cattle, horses and goats on Muldersdrift smallholdings
- Irrigating large gardens in Noordheuwel and Monument
- Supplying guest houses and venues near the Cradle
- Industrial washdown and yard cleaning at Chamdor businesses
- Backup household water during Mogale City outages
Wellpoint or Borehole?
Ruled out. Dolomitic ground offers neither loose sand nor a shallow water table. A drilled borehole is the only route.
Approval and Abstraction
Krugersdorp falls under Mogale City. Both main metros require approval before drilling. The City of Johannesburg requires an application to its Environment and Infrastructure Services Department, and an approved application comes with a drilling certificate that has to be kept on site while the rig works; drilling without one risks a fine and impoundment of equipment. The City of Ekurhuleni requires authorisation, with applications reviewed by its Dolomite Section and by Water Demand Management. Elsewhere, including Mogale City, confirm the municipality's current requirements. Separately, the National Water Act governs how much you may abstract: reasonable domestic use generally falls under Schedule 1, and in 2026 the Department of Water and Sanitation confirmed that households using borehole water for reasonable domestic purposes do not need to register nationally. Commercial, agricultural and larger abstraction may need registration or a water use authorisation. Rules change, so confirm the current position before drilling.
Where the ground is dolomitic there is a further layer. Development on dolomite land is governed by SANS 1936 and stability information is held by the Council for Geoscience, so additional approvals may be needed before a rig is allowed on site. Establish that early, because it affects the programme as well as the paperwork.

Borehole Prices in This Area
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 - R1,300 /m | Chert bands drill very slowly and cavities can mean redrilling, so the range is wide. |
| uPVC casing, installed, per metre | R400 - R700 /m | Diameter and class, plus the wad thickness, which is not known before drilling. |
| Mobilisation and site establishment | R2,500 - R9,000 | 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 | R75,000 - R220,000+ | 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 - 2026 guides quote per-metre drilling rates for Gauteng ranging from under R300/m to R1,500/m, a spread of more than five to one - 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
Where is the dolomite around Krugersdorp?
Malmani dolomite lies mainly to the north and west of Krugersdorp, extending toward Muldersdrift, Sterkfontein and the Cradle of Humankind. To the south, Witwatersrand rocks and the old mining belt dominate.
Suburbs between the two can sit near the boundary, so confirming the ground under your erf is the first job.
Can I drill a borehole near the Cradle of Humankind?
Properties near the Cradle often sit on dolomite, and some fall within protected or heritage zones. Mogale City requirements, environmental rules and any World Heritage Site conditions should be checked first.
Commercial operations such as wedding venues, lodges or restaurants may also need national water use authorisation, depending on how much water they draw and how it is used.
Is water from Krugersdorp's southern suburbs affected by mine decant?
It can be. The 2002 decant began in this area, and groundwater near the West Rand basin may carry acidity, sulphate and metals. Water quality varies, so a full laboratory analysis is essential.
Away from the mining belt, dolomite water is often of better quality, but it can still be hard and should be tested before drinking or pool use.
Why do drilling costs vary so much on Krugersdorp dolomite?
Chert bands slow progress badly, open cavities can swallow drilling air and water, and soft wad must be cased through. These conditions are hard to predict and can change the time and materials needed.
For that reason no honest driller fixes depth, yield or final cost upfront. A quote that spells out these variables and how they are charged helps you plan.
