Elardus Park sits on Pretoria Group rock on the southern side of the city, with the dolomite compartments not far below and to the south.
Whether a hole reaches that dolomite is the difference between a modest borehole and a strong one, and it is settled by drilling.
What Is Under Elardus Park
| Formation | Where it sits | What it means for drilling |
|---|---|---|
| Timeball Hill Formation shale and quartzite | The higher ground and low ridges through the southern suburbs | Shale is quick going, quartzite bands are not. Either way the water sits in fractures and bedding partings rather than throughout the rock. |
| Malmani dolomite beneath | The compartments below and to the south that feed the Fountains and Rietvlei springs | Reaching the dolomite generally transforms the yield. How deep that contact sits under a given stand is the main thing nobody knows before drilling. |
| Karoo outliers and surface deposits | Scattered through old pre-Karoo depressions across the ground south of the city | Younger material filling buried valleys. It is soft, needs casing, and does not necessarily show at surface, so it is found by drilling. |

- Depth is genuinely uncertain here because it depends on where the dolomite contact sits under your stand.
- Two neighbouring stands can need very different depths which is a function of the faulted contact rather than of workmanship.
- Casing requirements vary with the cover and Karoo material where present adds to it.

What to Watch For Here
Depth to the dolomite contact is the whole question. Shale and quartzite of the Pretoria Group carry water only in fractures, while the dolomite beneath is a genuinely strong aquifer. The contact between them is faulted and irregular, so how deep it sits under a particular stand is the largest unknown in the project.
Suburban stands with mature planting set the demand. Elardus Park is long established and the gardens are grown in. Demand peaks through the dry winter months, which is when a borehole earns its keep and when the municipal network is most stretched.
What the Water Is Used For
- Keeping established gardens alive from June to October
- A fallback for when the reticulated supply fails
- Sports turf and institutional landscaping
- Cutting the volume bought from the metro each month
- Topping up the pool, subject to what the analysis says
Wellpoint or Borehole?
Ruled out here. A wellpoint needs metres of loose sand above shallow water, and the shale, quartzite and dolomite under these suburbs provide none of it.
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.
Dolomitic ground carries an extra requirement. SANS 1936 governs what may be built on it, and the Council for Geoscience holds the stability records the metro works from, which means approvals can be needed before drilling starts rather than after. It is worth checking at the planning stage, since it can move dates rather than just add forms.

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 | R500 - R1,200 /m | What drives this is how far down the dolomite sits. The shale above it is quick going; the quartzite bands and the dolomite itself are not. |
| uPVC casing, installed, per metre | R400 - R700 /m | Both the weathered shale and any buried Karoo material need casing, and neither shows its depth from the surface. |
| 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.
Elardus Park Borehole FAQs
Will my Elardus Park borehole reach dolomite?
It may, and if it does the yield usually improves substantially. But the contact is faulted and irregular, so depth to it varies across short distances.
That is why a per-metre quote is the right structure here, and why a fixed-depth price should be treated with some caution.
How much water does a typical garden here need?
More than most owners expect, and almost all of it in the dry months. An established Highveld garden through August and September is a substantial daily demand.
The practical answer is usually a moderate sustainable yield plus enough storage to cover the peak irrigation window, rather than chasing a high-yield borehole.
Is borehole water safe to drink in Elardus Park?
Not automatically, anywhere. Yield and water quality are entirely unrelated, and a strong borehole can produce water that needs treatment.
A laboratory analysis against SANS 241 is what settles it, and it should be done before the water is used for drinking rather than afterwards.
How disruptive is drilling on a suburban stand?
It is noisy and dusty for the day or two the rig is working, and it needs a route in and a working area. Neighbours are usually worth warning.
Beyond that the footprint is small. Reinstating the working area and the trench to the tank or pump position is the part worth confirming is included in the quote.
