Midstream sits toward the southern edge of the Tshwane dolomite, in ground where the dolomite, Karoo cover and the granite of the dome to the south all come close together.
That makes it one of the few areas around Pretoria where confirming what is actually under a specific stand is a genuine first step rather than a formality.
What Is Under Midstream Estate
| Formation | Where it sits | What it means for drilling |
|---|---|---|
| Malmani Subgroup dolomite | The bedrock beneath most of the suburb, part of the Chuniespoort Group | Water here occupies solution channels and widened fractures rather than the rock mass, which is why two holes on the same street can return very different yields. |
| Chert and chert breccia | Bands within the dolomite and residual rubble above it | Punishing on equipment. Chert-rich sections drill far more slowly than clean dolomite, and where they sit is only established once the hole is underway. |
| Wad and residual soil | The leached mantle between the soil and dolomite bedrock | The compressible layer above bedrock. It varies in thickness across one stand and will not stand open, so it has to be cased. |

- Yields are the least predictable in the city high where a solution cavity is intersected, disappointing a stand away.
- Casing through the wad horizon is not optional and its thickness is unknown until drilling starts.
- Loss of circulation is common when a cavity is opened, and the rig has to be equipped for it.
Where We Work Around Midstream Estate

- Retirement village and estate common areas
- Business park stands
- Smallholdings on the estate periphery
What to Watch For Here
The ground here sits near a geological boundary. The belt of Karoo material running through the Olifantsfontein area rests on the older rocks in old depressions, and the dolomite gives way southward toward the granite of the Johannesburg dome. Which of those a particular stand sits on changes the target, the depth and the casing plan, so it is worth confirming rather than assuming.
Estate rules govern the practical side. Access for a rig, permitted working hours, reinstatement of landscaping and where a headworks may be positioned are all usually set by the homeowners association. Those need clearing before a date is booked, and they occasionally rule out the best geological position.
What the Water Is Used For
- Communal gardens in townhouse and cluster developments
- Watering lawns and beds through the driest months of the year
- Keeping water on the property through supply outages
- Taking irrigation demand off the municipal meter
- Grounds at schools, clubs and places of worship
Wellpoint or Borehole?
Ruled out. A wellpoint needs unconsolidated ground and a shallow water table, and dolomitic terrain offers neither. There is no primary sand aquifer under Pretoria comparable to a coastal sand plain, so a drilled borehole is the only 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.
There is an additional step on dolomite. Stability classifications for this land sit with the Council for Geoscience and development on it falls under SANS 1936, so the City may want sight of that before a rig is permitted on the stand. Raise it early; the delay, if there is one, is in the approval rather than in the drilling.

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 | Chert bands drill very slowly. Cavities can also mean redrilling, which is why the range here is wider than elsewhere in the metro. |
| uPVC casing, installed, per metre | R400 - R700 /m | Depends on diameter and class and on the depth of the leached horizon above bedrock, which varies 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.
Midstream Estate Borehole FAQs
Is Midstream on dolomite?
Much of the surrounding area is, but this is ground where the dolomite, Karoo cover and the granite to the south all come close together, and the boundaries are faulted.
It is genuinely worth confirming what sits under your specific stand before drilling, because it changes the drilling approach and whether the metro's dolomite requirements apply.
Can I drill a borehole in an estate like Midstream?
Usually, but the homeowners association's approval comes first and its conditions shape the job, from rig access and working hours to where the headworks may sit.
Getting those conditions in writing before booking avoids the common problem of a rig arriving to find it cannot reach the agreed position.
Would a shared estate borehole make more sense than individual ones?
Frequently, for common-area irrigation. One properly sited, tested and equipped borehole feeding shared storage is usually a better investment than several small ones on individual stands.
It also concentrates the compliance obligations in one place, which is simpler to manage than a scatter of separate installations.
What water quality should I expect at Midstream?
It depends on which formation the water comes from. Dolomite water is typically hard; water from Karoo material can carry different characteristics entirely.
That is precisely why the analysis matters here rather than being taken as read, and why treatment should be specified from the result rather than fitted in advance.
