Kommetjie sits on sandy coastal ground at the Atlantic edge, where water is shallow and salinity deserves measuring.
Wind and salt exposure also shape what surface equipment survives here.
What Is Under Kommetjie
| Formation | Where it sits | What it means for drilling |
|---|---|---|
| Valley sand deposits | The flat low ground between the mountain ranges | Unconsolidated sand of appreciable depth with a shallow water table. Wellpoints work, and boreholes need screening and a gravel pack. |
| Cape Granite Suite | The Peninsula batholith on the valley sides and rising ground | Weathered mantle and jointing. Slope properties reach rock quickly and revert to fracture-dependent yields. |
| Table Mountain Group sandstone | The higher mountain ground either side | Hard fractured rock, and the recharge source for the valley below. |

- Measure chloride and sodium even well inland, since the fill runs between two coastlines.
- Screening and gravel pack are essential where the hole passes through unconsolidated sand.
- Ask neighbours if you are on the flat. A continuous sand aquifer makes their result genuinely informative.
Where We Work Around Kommetjie
- Kommetjie village and the beachfront
- Imhoff's Gift and Ocean View approaches
- Sunnydale and Noordhoek boundaries
- Slangkop and the lighthouse side
- Smallholdings on the village fringe
- Holiday and rental properties
- Estate and complex developments
What to Watch For Here
Salinity is a real question at this exposure. Sitting on the Atlantic edge, raised chloride and sodium are plausible and heavy abstraction can worsen it. Measure before planning anything around the water.
Wind and salt spray are hard on surface equipment here, and properly housed control gear with corrosion-resistant fittings lasts substantially longer than the standard specification.
What the Water Is Used For
- Garden and lawn irrigation on village stands
- Smallholding irrigation on the fringe
- Garden maintenance at rental and holiday houses
- Estate and complex shared landscaping
- Pool top-up, subject to salinity testing first
- Backup supply when the municipal feed is interrupted
Wellpoint or Borehole?
Practical on the valley floor and impractical on the valley sides. The sand fill takes a point readily; the granite on the slopes does not. Establishing which applies to your stand costs a site visit and saves pricing the wrong thing.
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 | R400 - R950 /m | Valley sand drills quickly; the granite on the valley sides does not. Which you are on changes the rate. |
| 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. |
| Wellpoint alternative | R6,500 - R10,000 | Where sand depth and a shallow water table allow it, this covers garden irrigation for a fraction of the cost. |
| Typical complete project | R55,000 - R160,000+ | 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.
Kommetjie Borehole FAQs
Is Kommetjie groundwater salty?
Plausibly, given the Atlantic exposure, and it needs measuring rather than assuming either way. Raised chloride, sodium and electrical conductivity are the parameters to request.
Heavy abstraction close to the shore can worsen it over time, so staying within a tested sustainable rate is the practical protection.
What equipment lasts in Kommetjie's exposure?
Properly housed control gear and corrosion-resistant fittings. Wind-driven salt is hard on anything exposed at surface, and the difference in service life is considerable.
It is a modest additional cost at installation that saves repeated replacement of switches, fittings and enclosures.
Can a Kommetjie smallholding use a borehole?
Often, and it needs proper yield testing because sustained irrigation draws very differently from garden watering.
Where abstraction goes beyond reasonable domestic use, registration or authorisation from DWS may be required in addition to registering the borehole with the City.
Is a wellpoint practical here?
On the sandy village ground, generally yes, and it is the cheap route for garden irrigation. Toward the rocky ground the picture changes.
The constraint is usually water quality rather than access, so the analysis matters more than the installation method.
