Midrand sits on the outer part of the granite dome, the same Halfway House granite the old village gave its name to. Most stands have a weathered granite mantle over hard fresh rock, with water typically found in fractures near the transition.
Character here swings from tight cluster complexes in Noordwyk and Carlswald to big lifestyle estates like Waterfall and open smallholdings around Blue Hills. Each brings different access, approval and water demand questions before a drilling site is picked.
What Is Under Midrand
| Formation | Where it sits | What it means for drilling |
|---|---|---|
| Halfway House granite and gneiss | The basement across the northern and western edge of the Johannesburg Dome | Hard and slow once fresh. Water sits in joints and fracture zones, so siting matters more than depth. |
| Thick weathered granite | The upper section, often deeper on the gentle open ground of the outer dome | Fast, unstable drilling that must be cased. A deeper weathered zone can store more water at its base. |
| Dykes, quartz veins and greenstone remnants | Linear intrusions and older schist slivers within the granite | Contacts are favoured targets. Greenstone remnants weather differently from granite and can change results over short distances. |

- Larger demand needs a proper yield test because estates and smallholdings draw steadily rather than occasionally.
- Casing through the weathered zone is standard and its depth varies from one end of a property to the other.
- Fracture zones and dyke contacts are the targets rather than a set depth.
Where We Work Around Midrand
- Waterfall estates and Waterfall City

- Kyalami Hills toward the Jukskei
- Northern edge toward Centurion and Olifantsfontein
What to Watch For Here
The far northern fringe may approach a different rock type. Geological maps place dolomite north of the granite dome toward Centurion and Olifantsfontein, so stands on Midrand's northern edge could lie nearer that contact than the rest of the suburb. Published geology and site history are worth checking first, because if dolomite is a real possibility the drilling method and ground stability questions change.
Estate rules come before rig access. Waterfall, Carlswald and other managed estates usually want written approval, set working hours and proof of insurance before a drilling rig enters. Paved internal roads, gatehouse height limits and narrow cul-de-sacs also shape where a truck can park, so the estate office is often the first call rather than the last.
What the Water Is Used For
- Keeping large estate gardens green through dry winters
- Topping up swimming pools without municipal water
- Watering paddocks and vegetables on Blue Hills plots
- Backup supply for complexes during Rand Water outages
- Washing vehicles and equipment on smallholdings
Wellpoint or Borehole?
Rarely. Outside the narrow alluvial strips beside the Jukskei and its spruits, the ground is clayey weathered granite with water below suction lift. A drilled borehole is the realistic option.
Approval and Abstraction
Midrand falls under the City of Johannesburg. Both main metros require approval before drilling. The City of Johannesburg requires an application to its Environment and Infrastructure Services Department, and an approved application comes with a drilling certificate that has to be kept on site while the rig works; drilling without one risks a fine and impoundment of equipment. The City of Ekurhuleni requires authorisation, with applications reviewed by its Dolomite Section and by Water Demand Management. Elsewhere, including Mogale City, confirm the municipality's current requirements. Separately, the National Water Act governs how much you may abstract: reasonable domestic use generally falls under Schedule 1, and in 2026 the Department of Water and Sanitation confirmed that households using borehole water for reasonable domestic purposes do not need to register nationally. Commercial, agricultural and larger abstraction may need registration or a water use authorisation. Rules change, so confirm the current position before drilling.
Where the ground is dolomitic there is a further layer. Development on dolomite land is governed by SANS 1936 and stability information is held by the Council for Geoscience, so additional approvals may be needed before a rig is allowed on site. Establish that early, because it affects the programme as well as the paperwork.

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 - R1,100 /m | The weathered mantle drills fast; fresh granite does not. Deeper holes for larger demand push the total up rather than the rate. |
| uPVC casing, installed, per metre | R400 - R700 /m | Casing runs through the weathered granite, which can be thicker on this open ground. |
| 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 | R60,000 - R180,000+ | 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.
Midrand Borehole FAQs
Is all of Midrand on granite, or does the rock change toward Centurion?
Most of Midrand is underlain by Halfway House granite, with a decomposed, clay-rich layer on top that has to be cased and harder rock below it. Water is typically held in joints and fractures rather than spread evenly through the rock.
Toward the northern boundary, the dolomite on the Centurion side is mapped not far away. If a property is close to that edge, check the geology before assuming ordinary granite conditions.
Can a borehole go in inside a Midrand estate such as Waterfall or Carlswald?
Often yes, but the estate's own rules decide the details. Many managed estates have architectural or environmental guidelines, approved contractor lists and limits on noise, working hours and heavy vehicles on internal roads.
Ask the managing agent or HOA early, and keep their written consent alongside the municipal application, which the City must approve before drilling starts.
Do Blue Hills and Glen Austin smallholdings need a different approach?
Plots there tend to have more space for the rig and more demand, from livestock, food gardens or several dwellings on one property. That justifies a more careful siting exercise and a proper yield test once the hole is drilled.
Where use goes beyond reasonable household needs, for example a commercial nursery, a DWS registration or water use authorisation may apply, separate from the municipal process.
How much water can a Midrand borehole be expected to give?
There is no honest way to promise a figure. Granite aquifers here generally fall in the low to moderate class, and boreholes on neighbouring stands can perform very differently depending on whether they meet a water-bearing fracture.
A pump test after drilling gives the real number, and the pump and storage are then sized to what the hole can sustain rather than to hopes.
