Plattekloof carries some of the largest residential stands in the northern suburbs, on Tygerberg ground where yields are modest by default.
The gap between demand and what the ground gives is the defining problem of a Plattekloof borehole project.
What Is Under Plattekloof
| Formation | Where it sits | What it means for drilling |
|---|---|---|
| Malmesbury Group | Beneath the area and at surface across the higher ground | Modest default yields. The productive holes are those that intersect fracture and fault zones. Salinity tends to run higher than in sandy ground. |
| Cape Granite Suite | Reaching into parts of the area | Weathered mantle and jointing hold the water. Contact zones with the shale are worth targeting. |
| Sand and superficial cover | Variable, thicker toward the Cape Flats side | Where it has useful depth it can hold shallow water. Where thin, it is only overburden to drill through. |

- Expect modest yields where the hole draws from Malmesbury rock, and design around storage rather than a larger pump.
- Salinity belongs in the analysis, being a documented characteristic of this groundwater.
- Test the yield before choosing a pump. Fracture-fed holes blow well briefly then sustain far less.
Where We Work Around Plattekloof
- Plattekloof 1, 2 and 3
- Plattekloof Glen and Welgelegen
- The Tygerberg slopes and larger estates
- Panorama boundary properties
- Complexes and security estates
- Edgemead-side approaches
- Institutional and hospital grounds
What to Watch For Here
Big gardens, modest ground. Malmesbury rock under the Tygerberg is not a high-yield default, and the stands here are large. Almost every Plattekloof project ends up needing storage to make a modest sustainable rate meet a heavy irrigation peak.
Slope access on the higher Tygerberg stands is worth checking early, since steep driveways and terraced gardens constrain a truck-mounted rig.
What the Water Is Used For
- Irrigation for large established gardens
- Security estate and complex landscaping
- Institutional and hospital grounds
- Keeping the pool level up, subject to what the analysis says
- Standby supply where interruptions are disruptive
- Equestrian and smallholding properties on the fringe
Wellpoint or Borehole?
Generally not viable, though cover depth decides it. Where sand over the rock is thin, which is usual, a driven point has nothing to work with. Where cover is thicker toward the flats it is worth assessing before pricing a borehole.
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 | R450 - R1,100 /m | Depends which formation you hit. Sandy cover drills fast; the Malmesbury rock and granite beneath it do not. |
| 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 | R65,000 - R190,000+ | 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.
Plattekloof Borehole FAQs
Can a borehole irrigate a large Plattekloof garden?
With storage, usually yes. The Malmesbury ground here yields modestly by default, while Plattekloof stands are large and their peak irrigation demand is heavy.
A tank filled at the sustainable rate and drawn down during irrigation resolves that mismatch. A larger pump does not - it simply draws the water level down to the intake faster.
Is Plattekloof ground good for drilling?
It is workable but not generous. Yields depend on intersecting fracture and fault zones in the Malmesbury rock or the contact with granite, rather than on the formation being uniformly productive.
That makes siting the decision worth spending on, and makes yield testing essential before any pump is selected.
Can a rig reach a stand on the Tygerberg slopes?
Usually, but it is worth confirming on site. The higher Plattekloof stands have steep driveways, terracing and mature planting, and a truck-mounted rig needs both a route in and a working area at the drilling point.
Establishing this early avoids quoting for work that turns out to be impractical.
Should I test for salinity in Plattekloof?
Yes. Relatively higher salinity is a documented characteristic of Malmesbury Group groundwater, and it matters for irrigating established gardens where sodium accumulates in soil across seasons.
Conductivity, chloride and sodium belong in the analysis before you commit to an irrigation layout.
