Kenilworth sits on the transition from granite footslopes to the sandier ground below, with large sporting and institutional grounds alongside established residential stands.
Those grounds carry concentrated irrigation demand that shapes how the systems are designed.
What Is Under Kenilworth
| 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. |

- Depth is an outcome, not a target. The hole continues until it meets a water-bearing fracture.
- Two adjacent stands can get very different results, which is the nature of fractured ground.
- Siting is the highest-value decision in a granite borehole project, ahead of every equipment choice.
Where We Work Around Kenilworth
- Kenilworth and Kenilworth Upper
- Claremont and Wynberg boundaries
- The racecourse and sporting grounds
- Harfield-side streets
- School and institutional properties
- Complexes and cluster developments
- Older established stands through the suburb
What to Watch For Here
Sporting and institutional grounds dominate the heavy demand here. Large irrigated turf areas need concentrated volume in a short watering window, which almost always means storage sized against the peak event rather than the daily total.
Ground varies across the suburb, from granite on the upper side to sandier cover lower down, which changes both depth and expected yield.
What the Water Is Used For
- Sports field and racecourse turf irrigation
- Educational and institutional grounds maintenance
- Residential garden irrigation on established stands
- Shared landscaping in townhouse and complex developments
- Topping up the pool, once the analysis supports it
- Standby water for planned and unplanned municipal shutdowns
Wellpoint or Borehole?
Ruled out across most of the granite ground here. A point needs unconsolidated material and a shallow table, and neither is present where rock reaches close to surface. The sandier lower ground is the exception worth checking rather than dismissing.
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.
Kenilworth Borehole FAQs
Can a borehole irrigate a sports field in Kenilworth?
Frequently yes, but the design is different from a domestic system. Turf needs concentrated volume in a short watering window, which is a peak-flow problem rather than a daily-volume one.
Storage sized against the peak irrigation event, filled steadily at the borehole's sustainable rate, is the standard answer.
What ground is under Kenilworth?
It varies across the suburb. The upper side sits on granite footslopes where yields depend on intersecting fractures, while the lower ground carries sandier cover with shallower and more predictable water.
That difference affects depth, cost and how reliable the supply will be through late summer.
How big a tank does a Kenilworth property need?
Size it against the peak irrigation event and its duration, not against the daily total, and add whatever reserve you want for a pump or power failure.
On sporting and institutional grounds that usually means considerably more storage than a domestic property needs, because the whole demand lands in a short window.
Is Kenilworth borehole water suitable for turf?
Usually, but salinity is the parameter to check. Sodium accumulating in soil across seasons degrades structure and infiltration, which shows up on turf before it shows up anywhere else.
Ask for conductivity, chloride, sodium and sodium adsorption ratio rather than a generic domestic panel.
