Rivonia is built on granite-gneiss, so drilling crosses a weathered upper layer before reaching solid rock. Water is commonly found in joints, fractures and along dyke contacts rather than in one continuous layer.
The area mixes freestanding family homes with a large concentration of office parks around Rivonia Road and the village shops. Liliesleaf Farm, now a heritage site, is a reminder that the suburb began as smallholdings.
What Is Under Rivonia
| Formation | Where it sits | What it means for drilling |
|---|---|---|
| Johannesburg Dome granite and gneiss | The basement rock under the whole suburb, part of the Kaapvaal Craton | Hard, slow drilling once fresh rock is reached. It holds water only in joints, fractures and quartz veins, so the hole has to intersect them to produce. |
| Weathered granite mantle | Between the topsoil and fresh rock, thickest on the gentler ground | Soft, collapsing material that is always cased through. The transition at its base is often where the first water is struck. |
| Dykes and fracture zones | Linear structures through the granite, sometimes visible as straight valley lines | These carry most of the water in fractured granite. Siting on one, rather than drilling deeper, is what improves the odds. |

- Siting targets fractures and dyke contacts because unbroken granite carries almost no water.
- The upper section drills fast and the fresh rock slowly so the total time depends on where one becomes the other.
- Granite water is usually soft and of good quality though nearby septic tanks and soakaways are worth keeping well clear of.

What to Watch For Here
Office parks have shared landscaping and shared rules. Many Rivonia business parks are run by a body corporate or managing agent, so one borehole affects several tenants and the common irrigation. Location, metering and who pays for pump maintenance should be settled before drilling, and heavier draw may need registering with the national department.
Former smallholding plots can hide old services. Some Rivonia properties were subdivided from older plots that once had their own wells, septic tanks or farm pipework. These are rarely mapped, so asking previous owners and checking the ground before setting up avoids surprises and keeps the new hole clear of any contamination they left behind.
What the Water Is Used For
- Irrigating common lawns at Rivonia business parks
- Watering family gardens in Edenburg and Petervale
- Standby water for offices during supply interruptions
- Filling pools and keeping garden water features running
- Washing vehicles and paving on the larger properties
Wellpoint or Borehole?
Rarely. Decomposed granite can look sandy, but it is mixed with clay and the water table usually sits well below suction lift. Only a thin strip of alluvium beside a spruit might suit a driven point. A drilled borehole is the realistic route here.
Approval and Abstraction
Rivonia 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.

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 | Decomposed granite drills quickly; fresh granite is slow and wears bits. The split between the two on your stand sets where the cost lands. |
| uPVC casing, installed, per metre | R400 - R700 /m | The depth of decomposed granite decides how much casing is needed, and it changes across short distances. |
| 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.
Rivonia Borehole FAQs
What rock will a borehole in Rivonia drill through?
Typically a cover of soft, decomposed granite first, which is cased to stop collapse, then harder granite and gneiss beneath. Water tends to come from fractures and the weathered transition zone.
Dolerite or diabase dykes cross the granite in places, and their contacts can be better targets where they can be identified from the surface.
Can a Rivonia office park share one borehole between tenants?
It can, and many parks use one borehole for common landscaping. The managing agent or body corporate normally decides, and shared draw beyond what a household would use may need a water use registration.
Fitting a simple meter on the supply line helps track how much is drawn and supports any reporting the authorities ask for.
Are there restrictions near the Liliesleaf heritage site in Rivonia?
Private homes nearby follow the same Johannesburg pre-drilling approval as the rest of the city. Work on or immediately beside a heritage site itself would involve the site owners and any heritage rules that apply.
For an ordinary house in the area, the main requirements are the municipal approval and a sensible, well-sealed site on the stand.
How long will a Rivonia borehole take to pay for itself?
There is no reliable rule, because yield, depth and how much mains water the borehole replaces all vary. Garden-heavy properties tend to see more benefit than small, mostly paved stands, and office parks with large lawns often recover costs faster than homes.
A quote can lay out the costs, but the real outcome depends on what the Rivonia granite delivers at that particular spot.
