Gordon's Bay is squeezed between the Hottentots Holland slopes and the sea, so properties here sit on very different ground within a short distance of each other.
Steep terrain is the practical constraint as often as geology is, and rig access is the first thing to establish.
What Is Under Gordon's Bay
The formations below are what a rig actually meets on a Gordon's Bay 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 | Beneath much of the lower-lying suburban ground | Water in the weathered mantle and in jointing below it. Depth to fresh rock varies, and the weathered zone needs casing. |
| Table Mountain Group sandstone | The Hottentots Holland and Helderberg slopes above the town | Hard fractured quartzite and the recharge source for the basin. Fracture-dependent yields, deeper holes. |
| Coastal and alluvial sands | The flatter ground toward the shoreline and the Lourens River | Shallower water in unconsolidated material, with salinity to watch closer to the sea. |

- The suburb spans two very different settings, so quotes vary far more between properties here than they do on uniform ground.
- Mountain-side stands drill deeper into granite and sandstone; coastal stands drill shallower into sand. Which one you are on decides the shape of the quote.
- Salinity is the coastal-side question and fracture luck is the mountain-side one. They are not the same project.
Where We Work Around Gordon's Bay
- Gordon's Bay village and the harbour side
- Harbour Island and the marina
- Mountainside and Van der Stel Park
- Temperance Town and Sir Lowry's Pass Village side
- The steeper upper streets toward Steenbras
- Coastal erven along the beachfront
What to Watch For Here
Slope and access decide more here than the formation does. Steep driveways, retaining walls and terraced stands constrain where a truck-mounted rig can work, and occasionally rule out the best-sited position.
Mountain-side and sea-side properties are different projects. Upper stands drill into granite and sandstone at depth; coastal ones hit shallower sand where salinity is the parameter to watch.
What the Water Is Used For
- Irrigating coastal gardens and lawn
- Rinsing salt off paving, walls and vehicles
- Pool top-up, subject to what the analysis says
- Standby supply through restrictions and outages
- Keeping mature planting alive through summer
Wellpoint or Borehole?
It depends where on the gradient you sit. On the sandy coastal ground a wellpoint is a real option for irrigation. On the granite footslopes it is not, because there is no saturated sand for a driven point to work in.
Water Quality in Gordon's Bay
Water off the mountain side is typically soft and clean; water on the coastal flats is more likely to carry iron and, closer to the shoreline, elevated salinity. The analysis is the only thing that tells you which of those you have.
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 Gordon's Bay
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 and sandstone drill slowly; the sandy coastal ground is faster and shallower. |
| uPVC casing, installed, per metre | R400 - R750 /m | Weathered granite and loose coastal sand both need casing, for different reasons. |
| 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.
Gordon's Bay Borehole FAQs
Can a rig reach a steep Gordon's Bay property?
Often, but it is a genuine question here rather than a formality. A truck-mounted rig needs a route in and level working space at the drilling point, and the steeper upper streets defeat both on some stands.
A site visit settles it before quoting. Where access is the binding constraint it sometimes shifts the hole to a workable position rather than the ideal one.
Is borehole water in Gordon's Bay salty?
Closer to the shoreline it can be, and pumping hard accelerates it. Properties higher on the mountain side are drawing from fractured rock rather than coastal sand and generally carry less salinity risk.
Yield testing plus a water analysis is what establishes both the sustainable rate and the quality before anything is designed around them.
Why do Gordon's Bay borehole quotes vary so much?
Because the area spans two distinct geological settings. Properties on the mountain side drill into granite and Table Mountain Group sandstone at depth; properties toward the coast drill shallow holes into sand.
Those are different projects with different costs. A quote that does not distinguish between them has not looked at your actual site.
Is the water in Gordon's Bay suitable for irrigating vines or an orchard?
Often, and it is a common use here. What matters is the salinity and sodium content, because both affect soil structure and plant tolerance over time rather than immediately.
An irrigation-specific water analysis is a different test from a domestic potability one. Ask for the right one for the crop before you commit to a layout.
