Lyttelton sits on the Centurion dolomite belt, where high yields and ground stability requirements come together.
Drilling here is a geotechnical exercise as much as a water one.
What Is Under Lyttelton
The formations below are what a rig actually meets on a Lyttelton property, and between them they govern the depth, the casing requirement and what the hole will realistically give you.
| Formation | Where it sits | What it means for drilling |
|---|---|---|
| Malmani Subgroup dolomite | The karst bedrock underlying much of Centurion and its surrounds | A high-yielding aquifer where cavities and solution channels are intersected, and the single most safety-sensitive formation to drill in the country. |
| Chert residuum and wad | The weathered blanket over the dolomite | Low-density, highly compressible material. Uncontrolled water movement through it is the mechanism behind sinkhole formation. |
| Syenite and diabase intrusions | Cutting the dolomite and forming compartment boundaries | They divide the aquifer into hydraulically separate compartments, which is why yields differ so sharply across short distances. |

- This ground carries genuine sinkhole risk, and drilling protocol on it is not a formality. Uncontrolled water loss into the subsurface is what triggers subsidence.
- Yields can be very high where cavities are intersected, and disappointing a street away, because compartments are hydraulically separate.
- Site stability assessment comes before drilling, not after. On dolomite that is the order of operations, full stop.

What to Watch For Here
Dolomite protocol is not optional on this ground. Site stability assessment, correct casing and sealing, and controlled water handling are what keep the project safe.
Older properties may have undocumented services, which on dolomite matters more than usual because leaking services contribute to subsidence risk.
What the Water Is Used For
- Irrigating established gardens and mature trees
- Topping up the pool, subject to what the analysis says
- Washing paving, vehicles and hard surfaces
- Standby supply when municipal water is interrupted
- Reducing a monthly municipal water bill
Wellpoint or Borehole?
No. Dolomite karst is the wrong setting for a driven point entirely, and attempting shallow abstraction on this ground raises the stability questions rather than avoiding them.
Water Quality in Lyttelton
Dolomitic groundwater is typically hard - high in calcium and magnesium - which scales kettles, geysers and irrigation fittings over time. It is otherwise generally good quality. Softening is straightforward once an analysis quantifies the hardness.
A water analysis is what turns that from a general expectation into a number for your specific hole, and treatment should be specified against the result rather than against the area's reputation.
Registration and Abstraction
Boreholes in the City of Tshwane are subject to municipal registration, and on dolomitic ground the City applies additional geotechnical requirements because of sinkhole risk. Cross-connection to the municipal supply is prohibited. The National Water Act governs abstraction on top of that: domestic use generally falls under Schedule 1, larger volumes may require registration or authorisation from the Department of Water and Sanitation. This is the one setting where the regulatory step is not paperwork - it is the safety case for the hole. Requirements change, so confirm your position before drilling.

Borehole Prices in Lyttelton
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 - R1,100 /m | Dolomite drills reasonably but cavity intersections complicate the hole and the protocol adds cost. |
| uPVC casing, installed, per metre | R450 - R850 /m | Casing and sealing through the residuum is a stability requirement here, not just a hole-stability one. |
| Mobilisation and site establishment | R3,500 - R12,000 | 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 | R90,000 - R240,000+ | 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 - different 2026 guides quote per-metre drilling rates for the same province that differ by a factor of three - 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.
Lyttelton Borehole FAQs
What does dolomite protocol actually mean?
In practice: a site stability assessment before drilling, casing and sealing through the compressible residuum, controlled handling of drilling water and no uncontrolled loss into the subsurface.
It adds cost. It is also the difference between a borehole and a subsidence problem on this ground, which is why it is not the place to accept the cheapest quote without asking what it includes.
Can Lyttelton boreholes yield well?
They can yield very well where solution cavities are intersected, which is one of the genuine advantages of dolomitic ground.
It is inconsistent, though, because dykes divide the dolomite into separate compartments. High yields and disappointing ones occur close together here.
Is it safe to drill a borehole in Lyttelton?
It can be done properly, but dolomitic ground carries real sinkhole risk and it is the one setting where the geotechnical question comes before the water question.
That means a site stability assessment first, a contractor who works to dolomite protocol, correct casing and sealing through the residuum, and no uncontrolled water loss into the subsurface. A contractor who shrugs at this on Centurion ground is the wrong contractor.
Why do yields vary so much between neighbouring Lyttelton properties?
Because dykes and intrusions divide the dolomite into separate compartments that do not share water. One compartment can be highly productive while the adjacent one is not.
It also means a neighbour's excellent borehole tells you less about your own prospects here than it would almost anywhere else.
