Komani sits below the Hangklip in Beaufort Group country, with dolerite dykes and sills cutting the mudstone and sandstone beneath the town.
Municipal supply reliability has driven most of the borehole demand here, and that demand has not been matched by a change in the geology.
What Is Under Komani
The formations below are what a rig actually meets on a Komani 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 |
|---|---|---|
| Beaufort Group, Adelaide Subgroup: Middleton and Balfour Formations | Most of the Karoo interior and the lower-lying districts | Shaly sandstone and arenaceous mudstone. A poor aquifer on its own, with background yields often under half a litre per second. |
| Beaufort Group, Tarkastad Subgroup: Katberg and Burgersdorp Formations | The higher ground toward the Stormberg and the northern districts | Sandstone-dominated in places, which helps, but still fracture-dependent rather than porous. |
| Jurassic dolerite dykes, sills and ring complexes | Intruded throughout the Karoo sequence | The reason boreholes work here. The dyke core is semi-permeable to impermeable; the yield is in the baked, thermally fractured contact zone beside it, where sustainable rates above 10 litres per second are achievable. |

- Target the contact, not the dyke. This is the single most useful thing to know about Karoo drilling. The intrusion fractured the rock it pushed through, and that fractured margin is the aquifer.
- Water strikes are often shallow, commonly in the top twenty metres, with many deeper fractures closed by weathering. Forty to eighty metres is the normal working range rather than two hundred.
- Recharge is only 2 to 7 per cent of rainfall, so a hole pumped beyond its tested rate declines and recovers slowly. The sustainable figure is the one that matters.
Where We Work Around Komani
- Queenstown central and Komani Park
- Ezibeleni and Mlungisi
- Top Town and the Hangklip slopes
- Whittlesea and Ilinge approaches
- Stock and mixed farms around the town
- Commercial and light industrial sites
What to Watch For Here
Yields are moderate at best and entirely siting-dependent, so a quote that assumes a good hole is making an assumption you are paying for.
Interrupted municipal supply has pushed a lot of properties to drill, and a borehole only replaces a municipal connection if it is tested, sized and stored properly.
What the Water Is Used For
- Household supply where the analysis allows it
- Garden, vegetable patch and fruit trees
- Standby supply through municipal interruptions
- Stock and poultry watering on larger plots
- Reducing a monthly municipal water account
Wellpoint or Borehole?
No. This is hard rock under thin, discontinuous cover, and the water table is well below suction lift. The only exceptions are river-valley alluvium and calcrete terraces along the Great Fish and the Orange, where a shallow point can work.
Water Quality in Komani
Karoo groundwater runs from fresh to genuinely saline, with dissolved solids across the basin recorded from 300 to over 6,000 milligrams per litre. Fluoride is the under-discussed hazard and is strongly associated with proximity to dolerite, with values up to 16 milligrams per litre recorded against a 1.5 guideline. Hardness is routine where calcrete and carbonate cement occur. The practical screening set here is conductivity, hardness, fluoride and coliforms.
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
Groundwater itself is regulated nationally rather than municipally, and we could not find a published borehole by-law for this district municipality. As the water services authority it can still require approval before a property draws on an alternative supply, so we confirm the local position before drilling rather than assuming it. Separately, the National Water Act governs how much you may abstract. Reasonable domestic use and small-scale garden watering generally fall under Schedule 1 and need no licence or registration, but taking more than 10 cubic metres a day from groundwater on a property must be registered, and irrigation or commercial volumes usually require registration or a water use authorisation from the Department of Water and Sanitation.

Borehole Prices in Komani (Queenstown)
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 - R1,150 /m | Mudstone drills reasonably; dolerite is hard and slow. Depth to the target contact is what moves the total. |
| uPVC casing, installed, per metre | R400 - R750 /m | Cased through the weathered and collapsing mudstone section, which can swell. Below that the rock is generally competent. |
| Mobilisation and site establishment | R3,000 - R16,000 | Access, distance 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 | R75,000 - R195,000+ | 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.
Komani (Queenstown) Borehole FAQs
Can a borehole replace municipal water in Komani?
For a household, often yes, provided the hole is tested, the pump is sized to the sustainable rate and there is storage to carry peaks.
Cross-connection to the municipal plumbing is a separate matter and is generally prohibited. The two supplies have to be kept physically separate.
What does a borehole cost around Komani?
Mid-range by national standards, though the mudstone and dolerite drill slowly enough to push the per-metre rate up.
The bigger variable is whether the first hole produces. Budget for siting properly rather than hoping a cheap hole lands well.
What are the chances of finding water at Komani?
Moderate, and almost entirely dependent on siting. The Beaufort rock itself is close to a non-aquifer, so a hole that misses the dolerite contact can be effectively dry at any depth.
Anyone promising water in the Karoo before surveying is selling confidence rather than groundwater. Drilling deeper into mudstone finds more mudstone.
Should I test Komani borehole water for fluoride?
Yes, and it is the test most often left off. Fluoride in Karoo groundwater is linked to dolerite proximity and has been recorded at more than ten times the guideline level in this region.
It cannot be seen or tasted, and it matters most for children because long-term exposure affects developing teeth and bone. Where it is present, treatment is specified against the measured level.
