Claremont sits on granite footslopes grading toward sandier ground, with a mix of large residential stands and a substantial commercial precinct.
Which side of that gradient a property sits on changes the depth, the cost and the construction.
What Is Under Claremont
The formations below are what a rig actually meets on a Claremont 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 |
|---|---|---|
| Cape Granite Suite | The Peninsula batholith underlying the footslopes and much of the lower-lying suburb | Water sits in the weathered mantle above fresh granite and in jointing below it. Depth to fresh rock varies over short distances, and the weathered zone almost always needs casing to keep the hole stable. |
| Table Mountain Group sandstone | The mountain slopes rising above the suburb | Hard fractured quartzite, and the principal recharge for the ground below. Yield here depends on whether the hole intersects a water-bearing fracture, not on how far down it goes. |
| Colluvium and sandy cover | The lower ground grading toward the Cape Flats side | Looser material of variable thickness that can hold shallower water, with correspondingly more exposure to what happens at surface. |

- Yield follows fractures, not depth. That is the single most useful thing to understand before you read a quote.
- The weathered zone needs casing, and how much of it there is varies between neighbouring stands on the same street.
- Spend on siting rather than metres. A structure-targeted survey changes the odds. Drilling deeper, on its own, usually does not.

What to Watch For Here
Upper and lower Claremont are different drilling propositions, and the difference shows up in depth as much as in yield.
Commercial properties have steady, year-round demand, which suits a moderate yield paired with proper storage rather than a high-flow system.
What the Water Is Used For
- Landscaping and grounds irrigation
- Washbays and hard-surface cleaning
- Non-potable process and cooling water
- Standby supply for continuity of operations
- Reducing a significant municipal water account
Wellpoint or Borehole?
Generally not viable on the footslopes themselves, because granite close to surface leaves a driven point nothing to work with. Properties on the lower, sandier ground are a different question and worth assessing before you assume a borehole is the only route.
Water Quality in Claremont
Granite and sandstone groundwater here is usually soft and slightly acidic, which is easy on the palate and hard on metal fittings. Iron is the common nuisance. A water analysis after testing tells you whether treatment is needed at all.
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 and wellpoints inside the City of Cape Town must be registered with the City. Separately, the National Water Act governs how much you may abstract: reasonable domestic use and small-scale garden watering generally fall under Schedule 1, while larger abstraction may require registration or a water use authorisation from the Department of Water and Sanitation. Requirements change, so confirm your position before drilling rather than after. Requirements change, so confirm your position before drilling.

Borehole Prices in Claremont
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 | Granite drills slowly. Depth to fresh rock varies considerably between neighbouring properties. |
| uPVC casing, installed, per metre | R400 - R700 /m | Diameter and class. Weathered-zone thickness is not known until drilling starts. |
| 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 | R80,000 - R220,000+ | 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.
Claremont Borehole FAQs
Does upper or lower Claremont drill better?
They drill differently rather than better or worse. The upper side is granite with fracture-dependent yields at greater depth; the lower side picks up sandier cover with shallower water.
A site assessment establishes which one your stand is, and that changes what a sensible quote looks like more than the suburb name does.
Can a Claremont business use borehole water?
For landscaping, washing and non-potable use, commonly, and it takes a real amount off a commercial water account.
Anything potable needs a full analysis and treatment matched to it, plus periodic retesting rather than a single result filed away at commissioning.
How deep is a borehole likely to go in Claremont?
There is no reliable answer before drilling, which is exactly why drilling is charged per metre. On granite the useful water is in fractures below the weathered mantle, and the depth at which those appear differs from stand to stand.
What a local contractor can give you is an expected range based on nearby holes, plus a per-metre rate so the cost tracks the actual depth rather than a guess.
Is a water survey worth it in Claremont?
On fracture-dependent ground it is the part of the budget that does the most work. Geophysics targets structure - fracture zones, contacts, dykes - and rules out the least promising positions on the property.
It improves the odds. It does not guarantee water, and anyone telling you otherwise is selling certainty that does not exist in hard rock.
