Woodhill sits on eastern ridge ground below the Bronberg, on Pretoria Group rock that changes character across the estate.
As on most estates here, the access rules shape the project as much as the geology does.
What Is Under Woodhill
| 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 | The most expensive ground in the metro to drill, and entirely dependent on fractures for any yield at all. |
| Silverton Formation shale | The lower ground and valleys on either side of the ridge | Faster going than the ridge above it, though it holds little water except where fractured or cut by an intrusion. |
| Scree, colluvium and boulder cover | The ridge footslopes and the upper stands | Boulders and broken rock of inconsistent depth. Casing through it is unavoidable, and it complicates getting the rig into position. |

- 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.
- Siting is the highest-value decision on this ground, ahead of every equipment choice.

What to Watch For Here
Estate landscaping standards raise the reinstatement bar. Golf estates hold landscaping to a consistent standard, which means the reinstatement after drilling and trenching is more demanding and more expensive than on an ordinary suburban stand. It belongs on the quote explicitly.
Visible headworks are usually restricted. Estates commonly require that pumps, tanks and headworks are screened or positioned out of sight. That constrains where equipment can go and occasionally lengthens the pipework run considerably.
What the Water Is Used For
- Communal gardens in townhouse and cluster developments
- Watering lawns and beds through the driest months of the year
- Grounds at schools, clubs and places of worship
- A fallback for when the reticulated supply fails
- Keeping the pool level up, depending on the water analysis
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 | 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 | 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.
Woodhill Borehole FAQs
What does an estate typically require before drilling at Woodhill?
Written approval covering the drilling position, the access route, working hours, where equipment will sit and the reinstatement standard.
Obtaining that before booking a rig avoids the common and expensive problem of a mobilisation that cannot proceed on the day.
Where can the tank and pump go on an estate stand?
Usually somewhere screened or out of sight, which is an estate rule rather than a technical constraint.
It sometimes means a longer pipe run from the borehole, and that cost should appear on the quote rather than emerging during installation.
Is the drilling itself difficult at Woodhill?
It varies with position. Ground nearer the ridge brings harder quartzite closer to surface; lower ground is shale and drills faster.
Yields are fracture-dependent throughout, so neighbouring stands can produce quite different results.
How much water does estate landscaping need?
More than most owners estimate, and almost all of it between June and the first summer rains.
Sizing against the tested sustainable yield with storage for the peak is what makes a system work through that window.
