Claremont mixes established residential stands with a substantial commercial core, and the two want very different things from a borehole.
Ground runs from granite on the upper side to softer cover toward the flats.
What Is Under Claremont
| Formation | Where it sits | What it means for drilling |
|---|---|---|
| Cape Granite Suite | The Peninsula batholith underlying the footslopes and much of the lower ground | Water occurs in the weathered mantle above fresh granite and in jointing below. Depth to fresh rock varies over short distances, and the weathered zone usually needs casing. |
| Table Mountain Group sandstone | The mountain slopes rising above the suburbs | Hard fractured quartzite and the principal recharge for the ground below. Yields depend on intersecting fractures. |
| Colluvium and sandy cover | The lower-lying ground toward the Cape Flats side | Looser material of variable thickness that can hold shallower water, with more surface exposure. |

- Yield follows fractures, not depth. That is the single most useful thing to understand before quoting.
- Treat local anecdote carefully. Granite results do not carry reliably across property boundaries.
- Spend on siting rather than metres. A structure-targeted survey changes the odds; drilling deeper often does not.
Where We Work Around Claremont
- Claremont and Claremont Upper
- Harfield Village and Lynfrae
- Kenilworth and Newlands boundaries
- The Claremont commercial and retail core
- School fields and institutional landscaping
- Sectional title and townhouse developments
- Older stands on the upper side
What to Watch For Here
Commercial sites are priced on continuity, not garden size. Retail and office premises in the Claremont core justify storage and sometimes standby pumping where an interruption carries a trading cost, and that belongs in the design rather than added later.
Small urban stands in Harfield and the older village streets often have very limited drillable area clear of services and structures, which reduces what siting can offer.
What the Water Is Used For
- Residential garden irrigation on the older stands
- Retail and office premises landscaping and washrooms
- Institutional and school property grounds
- Complex and townhouse communal areas
- Pool replenishment after the water has been checked
- Standby supply where trading interruptions carry a cost
Wellpoint or Borehole?
Generally impossible on the footslopes themselves, since granite close to surface leaves a driven point nothing to work with. Properties on the lower ground with sandier cover are a different question and worth assessing before you assume a borehole is the only route.
Registration and Abstraction
Boreholes and wellpoints here must be registered with the City of Cape Town. 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.

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 | 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
Can a Claremont business use borehole water?
Often, for irrigation, washrooms, cleaning and other non-potable use, which captures most of the saving without the compliance burden of potable supply.
Design around peak demand and the continuity you need. Where an interruption costs trading hours, storage and sometimes a standby pump are worth pricing from the start.
Is there room to drill on a small Harfield stand?
Sometimes, and it needs checking rather than assuming. The drilling point must clear municipal services, sewer lines, structures and boundary walls, and a rig needs a working area around it.
On very small urban stands there may be only one viable position, which limits what a survey can contribute beyond confirming it.
Does Claremont ground vary across the suburb?
Yes. The upper side sits on granite with fracture-dependent yields and greater depth, while the ground toward the flats carries more cover and shallower water.
That changes both the expected depth and the cost, which is why the per-metre quoting structure matters here.
What treatment does Claremont borehole water usually need?
It depends entirely on the analysis, and it varies with which part of the suburb the water comes from. Shallower water on the lower ground is more exposed and needs microbiological attention.
Deeper granite water behind a properly sealed casing is generally better protected, but that is still no substitute for testing.
