Die Wilgers sits on the eastern side of the city between the ridge ground and the shale valley, on Pretoria Group rock throughout.
Yields depend on structure rather than the rock mass, so siting outweighs depth in determining the result.
What Is Under Die Wilgers
| 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 | Very hard and very slow to drill, and the single largest cost driver on this ground. Yield is entirely fracture-dependent. |
| Silverton Formation shale | The lower ground and valleys on either side of the ridge | Softer and quicker to drill, but a weak aquifer on its own. The better targets sit at fracture zones and intrusive contacts within it. |
| Scree, colluvium and boulder cover | The ridge footslopes and the upper stands | Loose blocky material of unpredictable thickness. It has to be cased through, and it is also what makes rig access difficult on these stands. |

- Two adjacent stands can get very different results which is the nature of fracture-controlled ground.
- Siting is the highest-value decision on this ground, ahead of every equipment choice.
- 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
Established stands with grown-in gardens. Die Wilgers has been settled long enough for the planting to mature, which sets a substantial dry-season irrigation demand. A moderate borehole with proper storage handles that better than a larger pump on an untested hole.
Rock close to surface on the higher ground. Toward the ridge the competent rock sits shallower, which changes both the drilling rate and how the hole is cased. It is a real difference within a single suburb.
What the Water Is Used For
- Keeping established gardens alive from June to October
- Continuity cover during water interruptions
- Keeping the pool level up, depending on the water analysis
- Shared landscaping in sectional-title schemes
- Cutting the volume bought from the metro each month
Wellpoint or Borehole?
No. Quartzite reaches close to surface across the ridge and the water table is far below the suction lift of a surface pump. There is nothing here for a driven point to penetrate.
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 | Quartzite is the hardest rock drilled in the metro. Ridge holes sit at the top of the range; footslope holes in shale sit 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.
Die Wilgers Borehole FAQs
What determines the cost of a borehole in Die Wilgers?
Depth first, because drilling is charged per metre, then casing, then how hard the rock is where the hole passes through it.
None of those are fully known before drilling, which is why an itemised per-metre quote is more honest than a single fixed figure.
Will a borehole cover a mature garden here?
Usually, once storage is sized for the peak irrigation window rather than for the average daily use.
That is what allows a moderate sustainable yield to meet a demanding schedule: the tank accumulates overnight and delivers in the morning.
Do I need to test the water if it is only for the garden?
It is still worth doing. Sodium and hardness affect soil structure and plants over time, and iron staining shows on paving and walls.
Testing is inexpensive relative to a mature garden, and it also establishes a baseline for comparison if the water changes later.
How often should the system be serviced?
A periodic check of water level, yield and pump performance is the sensible interval, and water quality is worth retesting from time to time.
Problems on boreholes develop gradually, and catching them early is consistently cheaper than responding to a failure.
