Pretoria West sits below the Daspoort ridge on Pretoria Group ground, with a mix of older residential stands and substantial industrial sites.
The industrial demand here is a different problem from suburban irrigation, and it changes both the testing and the treatment question.
What Is Under Pretoria West
| Formation | Where it sits | What it means for drilling |
|---|---|---|
| Silverton Formation shale | The broad valley ground between the northern and eastern quartzite ridges | The thickest shale unit in the Pretoria Group and the rock under most of these suburbs. It drills quickly but is a weak aquifer in itself; yield depends on fracturing rather than on the rock mass. |
| Diabase dykes and sills | Cutting across the shale throughout the Pretoria valley | Often the best target on this ground. Fractures concentrate along the contact between an intrusion and the shale it cuts, and that is where useful yields are usually found. |
| Weathered shale and residual clay | The upper section on most stands | Clay-rich and unstable. Casing through to sound rock is a requirement, not a refinement. |

- Siting is about finding structure, not depth because the shale itself carries little water between fractures.
- Dyke contacts are the targets worth locating and they are exactly what a survey is looking for on this ground.
- Yields here are usually modest but workable which is well suited to irrigation with storage rather than to high continuous draw.

What to Watch For Here
Industrial land raises the contamination question properly. Long-established industrial activity means historical ground contamination is a genuine consideration rather than a box to tick. Water quality testing on this ground should be thorough and should be repeated, and it should not be assumed that clear water is clean water.
The Daspoort ridge sets the northern boundary. The quartzite ridge running east-west through here is hard, slow drilling, and where a stand sits relative to it changes the rate considerably. Valley ground to the south drills much faster.
What the Water Is Used For
- Industrial process, wash-down and dust suppression
- A fallback for when the reticulated supply fails
- Keeping established gardens alive from June to October
- Lowering a water bill driven mostly by outdoor use
- School, sports field and institutional grounds
Wellpoint or Borehole?
Not an option. The residual clay over the shale is not the unconsolidated, permeable material a driven point needs, and the water table sits well below suction range. A drilled borehole is the route to groundwater here.
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 | R450 - R1,000 /m | This is the quickest ground in the city to drill, and the per-metre rate reflects that relative to the ridges and the dolomite belt. |
| uPVC casing, installed, per metre | R400 - R700 /m | The weathered clay above the rock is what has to be cased through, so its depth decides the length required. |
| 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.
Pretoria West Borehole FAQs
Is borehole water safe to use on an industrial site in Pretoria West?
It depends entirely on the analysis and on the intended use. For dust suppression or wash-down the requirements are far less demanding than for anything entering a process or reaching people.
Given the industrial history of this ground, a thorough analysis and a schedule of repeat testing is the sensible approach rather than a single test at commissioning.
Can historical contamination affect a borehole?
It can. Contaminants can move through the subsurface, and a borehole that penetrates a contaminated zone can draw from it or, if badly constructed, connect one zone to another.
Proper casing and grouting matter for that reason as much as for hole stability, and on this ground they are worth specifying explicitly.
What volumes can an industrial borehole supply here?
That is a pumping test question, and for industrial use the test should be longer and more rigorous than a domestic one because the demand is continuous.
Volume also has regulatory consequences: sustained industrial abstraction generally falls outside Schedule 1 and requires registration or authorisation.
Does drilling near the Daspoort ridge cost more?
Yes, where the hole has to pass through quartzite. It is among the hardest and slowest rock in the metro to drill.
Stands on the valley ground south of the ridge are considerably faster going and usually cost less per metre.
