Montana Park sits on Bushveld Complex ground north of the ridge, on the same norite and gabbro that underlies the northern suburbs generally.
Yields track the depth and quality of weathering rather than the total depth of the hole.
What Is Under Montana Park
| Formation | Where it sits | What it means for drilling |
|---|---|---|
| Bushveld Complex norite and gabbro | The bedrock across the ground north of the Magaliesberg ridge | Coarse mafic rock that carries water only where it is deeply weathered and jointed. Where it is fresh and unfractured it is close to barren. |
| The weathered mantle | The zone between soil and fresh rock, from a few metres to tens of metres thick | The main water-bearing horizon on this ground, which is why depth to fresh rock matters more here than total depth does. |
| Granophyre ridges and diabase dykes | The low ridges and intrusions cutting the mafic sequence | Water follows the joints and the intrusive contacts. Finding those is the point of a survey on this ground. |

- Depth of weathering is the thing that matters rather than how deep the hole goes in total.
- Drilling past fresh unfractured norite adds cost without adding yield so knowing when to stop is part of the job.
- Iron and manganese are worth testing for because mafic ground more often produces water that stains and needs treatment.

What to Watch For Here
Newer suburbs, newer infrastructure, same constraint. Montana Park is more recently developed than the older northern suburbs, but development has been rapid and supply pressure at the network edges is still a recurring complaint. Storage is what turns a borehole into a usable standby supply.
Fresh norite is close to barren. Where the rock is unweathered and unjointed it holds very little water, and no amount of additional depth changes that. Recognising the base of weathering and stopping is a judgement that affects the final bill directly.
What the Water Is Used For
- Irrigation over the long dry season before the summer rains
- A fallback for when the reticulated supply fails
- Communal gardens in townhouse and cluster developments
- Taking irrigation demand off the municipal meter
- Pool filling where the water quality allows it
Wellpoint or Borehole?
Ruled out here. Weathered norite produces a heavy clay soil, which is the opposite of what a driven point requires, and the usable water sits within the deeper weathered rock.
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 | R500 - R1,200 /m | Progress is fast until the hole reaches sound rock, at which point it slows considerably. That depth varies from stand to stand. |
| uPVC casing, installed, per metre | R400 - R700 /m | The weathered zone above fresh rock is what gets cased, and it ranges from a few metres to several tens. |
| 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.
Montana Park Borehole FAQs
Is deeper always better on this ground?
No, and it is one of the more expensive misconceptions. Fresh unweathered norite holds very little water, so drilling past the weathered zone into it adds cost without adding yield.
A contractor working on a per-metre rate should be able to explain what target is being pursued rather than simply continuing.
Will a borehole in Montana Park cover an outage?
Only with storage, and ideally with a backup power arrangement. A submersible pump stops when the power does.
A tank sized for a few days of essential household use is what actually keeps water available during an interruption.
How does water quality here compare with south of the ridge?
Iron and manganese are more common in water from mafic rocks, and hardness is generally lower than in the dolomite water south of the city.
Neither can be assumed. A SANS 241 analysis is what establishes what, if any, treatment is appropriate.
How much does a complete installation cost here?
The range is wide because depth is unknown until the hole is drilled, and depth drives the total.
The indicative table above is for budgeting, not quoting. An itemised written quote against your site is the only figure that means anything.
