Mooikloof sits on the eastern ridge ground, on large stands where quartzite and shale alternate over short distances.
The stand sizes give real freedom in siting, which matters more here than it does on ground where the aquifer is continuous.
What Is Under Mooikloof
| 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 | The valley rock either side. Cheaper per metre, with the useful yields concentrated at structural features. |
| Scree, colluvium and boulder cover | The ridge footslopes and the upper stands | Unstable surface cover that varies sharply across one stand. It drives both the casing requirement and the access problem. |

- 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
Large stands mean large irrigation demand. A hectare-scale garden is a genuinely different proposition from a suburban one, and it is easy to underestimate. The sensible sequence is to test the borehole properly, then design the irrigation around what it sustains, rather than the reverse.
Long driveways change the pipework cost. On large stands the distance from the borehole to the tank, and from the tank to the point of use, becomes a meaningful cost item in its own right. It is worth having that on the quote rather than discovering it during installation.
What the Water Is Used For
- Keeping established gardens alive from June to October
- Stock watering and paddock irrigation on larger stands
- Continuity cover during water interruptions
- Pool filling where the water quality allows it
- Common areas across complexes and estate developments
Wellpoint or Borehole?
Not possible. Between the scree cover and the quartzite beneath it, a driven point stops within the first metre, and the water it would be looking for sits far deeper.
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 | The rate here is the highest in the city because the rock is. Coming off the ridge onto the shale footslopes brings it down. |
| uPVC casing, installed, per metre | R400 - R700 /m | The scree and boulder mantle is the section needing casing, and its depth is notoriously inconsistent on these slopes. |
| 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.
Mooikloof Borehole FAQs
Can one borehole irrigate a large Mooikloof stand?
Sometimes, but a hectare-scale garden is a substantial continuous demand and one moderate borehole may not cover it in the dry season.
The honest approach is to establish the sustainable yield by testing first, then design the irrigation to fit it, with storage doing the work of bridging peaks.
Does a large stand improve the odds of good water?
It gives more scope to site the hole well, which genuinely helps on fracture-controlled ground where position matters more than depth.
It does not change the geology underneath, so it improves the probability without guaranteeing the result.
Are pipework runs a big cost on large properties?
They can be. Distance from the borehole to storage and from storage to the point of use adds up, and larger runs need larger diameter to avoid friction losses.
It should be an explicit line on the quote, because it is one of the more common sources of unexpected cost on big stands.
Does watering paddocks need registration?
Possibly. Reasonable domestic use and a garden fall within Schedule 1 of the National Water Act; watering livestock commercially or irrigating at agricultural scale generally does not.
It is worth establishing your position with the Department of Water and Sanitation before drilling rather than after the system is built.
