Wierdapark sits on the dolomite belt through Centurion, where yields depend on intersecting cavities rather than on reaching a particular depth.
It is an established suburb with mature gardens, which sets both the demand and the access constraints.
What Is Under Wierdapark
| Formation | Where it sits | What it means for drilling |
|---|---|---|
| Malmani Subgroup dolomite | The bedrock beneath most of the suburb, part of the Chuniespoort Group | Productive but erratic. The water is in the voids and fracture zones, so results depend on what the hole intersects rather than on how far down it goes. |
| Chert and chert breccia | Bands within the dolomite and residual rubble above it | Very slow going. Progress through a chert band can be a fraction of the rate through clean dolomite, which is why per-metre quotes here carry a wide range. |
| Wad and residual soil | The leached mantle between the soil and dolomite bedrock | Soft leached material that will not hold an open hole. Its thickness is discovered during drilling, which is why casing should be priced per metre. |

- 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.
- Casing through the wad horizon is not optional and its thickness is unknown until drilling starts.

What to Watch For Here
The dry season here runs long. Pretoria's rain falls in summer thunderstorms and essentially stops between about May and October. That means garden demand peaks precisely when there is no rain to supplement it, which is the opposite of the pattern in the winter-rainfall parts of the country and the main reason boreholes make sense on this ground.
Established suburbs mean older services. Wierdapark's underground infrastructure has been in the ground a long time, and on dolomite the interaction between leaking services and karst instability is well documented. Siting a borehole clear of existing lines is worth the effort.
What the Water Is Used For
- Garden irrigation through the dry Highveld winter
- Pool filling where the water quality allows it
- Standby supply when the municipal mains go down
- Lowering a water bill driven mostly by outdoor use
- School, sports field and institutional grounds
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 | Chert bands drill very slowly. Cavities can also mean redrilling, which is why the range here is wider than elsewhere in the metro. |
| uPVC casing, installed, per metre | R400 - R700 /m | Set by diameter and class, and by how much wad has to be cased through. That thickness is found during drilling, not before it. |
| 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.
Wierdapark Borehole FAQs
When is a borehole most useful in Wierdapark?
Through the dry season, which on the Highveld runs from roughly May to October. That is when gardens need the most water and when nothing falls from the sky to help.
It is also when municipal demand peaks across the metro, so it is when restrictions and supply interruptions are most likely to bite.
Will the borehole run dry in the dry season?
A properly tested borehole should not, because the yield test is designed to establish what the hole sustains rather than what it produces briefly.
Water levels do fluctuate seasonally on dolomite as elsewhere, which is exactly why systems should be sized against the tested sustainable yield and not against the best figure seen on the day of drilling.
How hard is the water likely to be in Wierdapark?
Dolomite groundwater is typically hard, since dissolved carbonate is what the aquifer is made from. Scaling in geysers, kettles and drip irrigation is the usual sign.
Hardness is treatable and is not in itself a health concern, but it should be measured by a laboratory rather than guessed at, because it varies between holes.
Do I need a survey before drilling in Wierdapark?
On karst ground it earns its cost more clearly than almost anywhere, because yield here is controlled by structures that a survey is specifically looking for.
It does not guarantee water and no honest contractor will say it does. It improves the odds of putting the hole in the right place, which on dolomite is the whole game.
