Waterkloof rises onto the ridge ground south of the city, where quartzite sits close to surface and drilling is slow.
It is the most expensive ground per metre in Pretoria, and access on the steeper stands is often the harder problem of the two.
What Is Under Waterkloof
| Formation | Where it sits | What it means for drilling |
|---|---|---|
| Magaliesberg Formation quartzite | The ridge itself and its dip slopes, running east through Pretoria as the Bronberg | Slow, expensive metres. Whether the hole produces depends wholly on intersecting an open fracture zone. |
| Silverton Formation shale | The lower ground and valleys on either side of the ridge | Quicker and cheaper per metre than the ridge, though it still needs a fracture zone or an intrusive contact to produce. |
| Scree, colluvium and boulder cover | The ridge footslopes and the upper stands | Loose and inconsistent cover that has to be cased through, and the main reason rig access is difficult on these stands. |

- Quartzite is the slowest ground in Pretoria and per-metre rates on the ridge reflect that.
- Two adjacent stands can get very different results which is the nature of fracture-controlled ground.
- Access is a real constraint on ridge stands and is worth settling at a site visit before anything is quoted.

What to Watch For Here
Steep, terraced stands are the defining constraint. Waterkloof and Waterkloof Ridge properties are cut into the slope, with retaining walls, terraced gardens and narrow approaches. A truck-mounted rig needs a route and a level working area, and on these stands there are often only one or two positions that qualify.
Quartzite is the slowest drilling in the metro. Ridge rock here is hard and it wears bits quickly. That shows up directly in the per-metre rate, and it is why quotes for Waterkloof sit at the upper end of the metro range.
What the Water Is Used For
- Keeping established gardens alive from June to October
- Keeping the pool level up, depending on the water analysis
- Standby supply when the municipal mains go down
- Playing fields and school grounds
- Reducing a municipal water account that has climbed steeply
Wellpoint or Borehole?
Ruled out entirely. Ridge ground is rock and boulder from very near surface, which is the worst possible setting for a wellpoint. A drilled borehole is the only route.
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.

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 | R600 - R1,400 /m | Nothing in the metro is harder on a bit than this quartzite. Holes on the ridge itself quote at the top of the range, and those on the footslopes below it lower. |
| uPVC casing, installed, per metre | R400 - R700 /m | Diameter and class, plus the depth of scree and boulder cover, which varies sharply across a single stand. |
| 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.
Waterkloof Borehole FAQs
Why is drilling more expensive in Waterkloof?
Quartzite. It is the hardest rock drilled in the metro, so progress is slow and consumables wear faster, and both feed into the per-metre rate.
Access on terraced stands adds to it, because setting up in a constrained position takes longer than working on flat open ground.
Can a rig reach a terraced Waterkloof stand?
Frequently yes, but not always in the position the geology would prefer. Retaining walls, narrow driveways and level changes all constrain the approach.
It is settled by a site visit before quoting, and it is the single most common reason a project here changes shape.
Are yields good on the ridge?
They are entirely fracture-dependent. A hole that intersects a good fracture zone can be productive, and one that misses can be poor despite considerable depth.
That variability is why siting carries more weight on ridge ground than anywhere else, and why a survey is more clearly worth its cost here.
Is a wellpoint an option in Waterkloof?
No. Quartzite reaches close to surface and the water table is far below suction range.
There is nothing here for a driven point to penetrate, so a drilled borehole is the only route to groundwater.
