Strandfontein sits on coastal sand right at the shoreline, which makes water shallow and salinity the first thing worth measuring.
Everything else about the project follows from what that analysis says.
What Is Under Strandfontein
| Formation | Where it sits | What it means for drilling |
|---|---|---|
| Cape Flats sand aquifer | Beneath the whole area, at varying thickness | An unconsolidated primary aquifer. Water sits in the pore spaces of the sand rather than in fractures, so it is relatively continuous and predictable. Boreholes need screening and a gravel pack. |
| Peat and clay lenses | Scattered through the sand sequence | Can perch water above the main table and can affect drilling and casing. Their position is not predictable in advance. |
| Malmesbury or granite basement | At depth below the sand | Rarely the target, since the sand above is more accessible and more productive. |

- Reaching water is rarely the difficulty. What the analysis says and how much the ground sustains are the questions worth spending on.
- A wellpoint covers most garden irrigation here for a fraction of what a drilled hole costs.
- Iron staining is the routine complaint, and it treats readily once the concentrations are actually measured.
Where We Work Around Strandfontein
- Strandfontein and Strandfontein Village
- Bayview and the beachfront properties
- Mitchells Plain boundary streets
- Pelican Park and Zeekoevlei approaches
- Coastal holiday and rental properties
- Community and sports facility grounds
- Smaller residential stands through the suburb
What to Watch For Here
Salinity is the defining issue here, more than anywhere else in the sandy southern suburbs, because the properties sit hard against the shoreline. Raised chloride and sodium are likely rather than possible, and over-abstraction makes it worse.
Wind-blown sand and shallow water mean sediment handling and dry-run protection matter more than usual on equipment here.
What the Water Is Used For
- Irrigating gardens and lawns on residential properties
- Landscaping on let and holiday stands
- Community and sports facility grounds
- Laundry and sanitary use on a dedicated, separated circuit
- Pool top-up, subject to salinity testing first
- A reserve to draw on during supply outages
Wellpoint or Borehole?
Usually the sensible option. Sand with a shallow water table is exactly what a driven or jetted point is built for, and for a garden it is often the whole answer. Stepping up to a borehole buys volume, better late-summer reliability and water that can be sealed against what happens at the surface.
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 - R900 /m | Cape Flats sand drills quickly, which keeps per-metre rates at the lower end of the metro range. |
| 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 | R45,000 - R130,000+ | 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.
Strandfontein Borehole FAQs
How salty is Strandfontein groundwater?
Raised chloride and sodium are likely rather than merely possible here, because the properties sit hard against the shoreline. It needs measuring before you plan anything around the water.
Over-abstraction close to the coast makes it worse over time, which is a reason to stay within a tested sustainable rate.
Can I fill a pool from a Strandfontein borehole?
Test first, because salinity and iron both matter for pool water and both are plausible here. Staining on pool surfaces is far easier to prevent than to remove.
Where the analysis supports it, top-up is straightforward. Where it does not, treatment costs need weighing against the saving.
Is a wellpoint practical this close to the sea?
Physically yes, since the sand and shallow water table suit a point well. The constraint is quality rather than access.
A shallow point draws from exactly the water most affected by salinity, so the analysis matters more here than the drilling method does.
What equipment problems are common here?
Sand ingress and dry running. Wind-blown sand and shallow water mean sediment reaches equipment more readily, blocking irrigation emitters and wearing pump impellers.
Sediment filtration and proper dry-run protection are worth fitting from the start rather than after the first pump failure.
