Rooihuiskraal sits on the Centurion dolomite, with the yield variability that comes with karst ground anywhere.
Stands here are generally more compact than in the older Centurion suburbs, which makes rig access and setback distances the practical constraint.
What Is Under Rooihuiskraal
| Formation | Where it sits | What it means for drilling |
|---|---|---|
| Malmani Subgroup dolomite | The bedrock beneath most of the suburb, part of the Chuniespoort Group | The strongest aquifer in the region, but an uneven one. Yield depends on striking a cavity or a fracture zone, not on reaching a particular depth. |
| Chert and chert breccia | Bands within the dolomite and residual rubble above it | Punishing on equipment. Chert-rich sections drill far more slowly than clean dolomite, and where they sit is only established once the hole is underway. |
| Wad and residual soil | The leached mantle between the soil and dolomite bedrock | The compressible layer above bedrock. It varies in thickness across one stand and will not stand open, so it has to be cased. |

- Yields are the least predictable in the city high where a solution cavity is intersected, disappointing a stand away.
- Budget for slow metres through chert which is the main reason dolomite quotes carry a wider range than quotes elsewhere.
- Loss of circulation is common when a cavity is opened, and the rig has to be equipped for it.

What to Watch For Here
Compact stands limit where the hole can go. A truck-mounted rig needs a working area and a route to it, and it needs to sit a sensible distance from boundaries, structures and services. On smaller stands that can leave only one or two viable positions, which constrains siting more than the geology does.
Setbacks from services matter more on dolomite. Keeping the hole and its headworks clear of sewer and water lines is standard practice everywhere, but on karst ground a leak concentrating water near a borehole collar is the specific mechanism behind most recorded sinkholes in this part of the city.
What the Water Is Used For
- Garden irrigation through the dry Highveld winter
- Standby supply when the municipal mains go down
- Common areas across complexes and estate developments
- Topping up the pool, subject to what the analysis says
- Taking irrigation demand off the municipal meter
Wellpoint or Borehole?
Not possible on this ground. Driven points rely on loose, permeable material within about seven metres of surface. Dolomite and its chert rubble stop a point immediately, and the water sits far deeper than a surface pump can lift it.
Registration and Abstraction
A completed borehole here should be registered with the City of Tshwane, and the responsibility for that sits with the property owner rather than with the driller. Separately, the National Water Act governs how much you may abstract: reasonable domestic use and small-scale gardening generally fall under Schedule 1, while larger, agricultural or commercial abstraction may require registration or a water use authorisation from the Department of Water and Sanitation. The position on domestic registration was being actively revised during 2026, so confirm your obligations before drilling rather than afterwards.
Because this is dolomitic ground there is a further layer. Development on dolomite land is governed by SANS 1936 and stability information is lodged with the Council for Geoscience, so the metro may require additional approvals before a rig is allowed on site. Establish that early, because it affects the programme rather than just 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 - R1,200 /m | The range is wide here for two reasons: chert horizons cut the penetration rate sharply, and a cavity can force a second hole. |
| uPVC casing, installed, per metre | R400 - R700 /m | Diameter and class, plus the thickness of the wad horizon, which is not known before drilling starts. |
| 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 | R70,000 - R200,000+ | 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.
Rooihuiskraal Borehole FAQs
Is there enough space on a Rooihuiskraal stand for a borehole?
Usually, but it is worth checking rather than assuming. The rig needs a working position with overhead clearance and a route in, and on a compact stand that can be the limiting factor.
A short site visit settles it and sometimes changes which corner of the property is realistic, so it is better done before quoting than after.
Can a borehole be drilled inside a complex in Rooihuiskraal?
Frequently yes, for common-area irrigation, but the decision usually sits with the body corporate or homeowners association rather than an individual owner.
Access, reinstatement and where the headworks will sit relative to shared services all need agreeing up front, and on dolomitic ground the metro's requirements apply as they would anywhere else here.
How close to the house can the borehole be?
A sensible working distance from structures and services is standard, and on dolomitic ground there is good reason to be conservative about it.
The exact position is a siting decision that balances the best geological target against access and setbacks, which is why it is settled on site rather than on a map.
Does Rooihuiskraal have the same sinkhole history as central Centurion?
The whole southern Tshwane dolomite belt has a recorded sinkhole history, and the documented causes are consistently leaking services and concentrated stormwater rather than the rock spontaneously failing.
That is why the sealing of the borehole collar and the drainage around it are treated as part of the job here rather than as an afterthought.
