Polokwane sits on Archaean granite-gneiss basement, where water occurs in the weathered mantle and in fracture and dyke contacts rather than in the rock itself.
A dry climate, a growing city and heavy groundwater reliance across the surrounding district all bear on what a borehole here can sustainably deliver.
What Is Under Polokwane
The formations below are what a rig actually meets on a Polokwane 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 |
|---|---|---|
| Goudplaats Gneiss | Much of the Polokwane plateau and north toward Blouberg | Gneiss, banded gneiss and migmatite. Weathering and fracturing reach 15 to 50 metres, and most holes fall between 30 and 85 metres. Just over half of recorded holes succeeded. |
| Hout River Gneiss | North and west of Polokwane | Leucocratic migmatite and hornblende-biotite gneiss. The better of the two, with a 60 per cent success rate and three quarters of holes between 25 and 75 metres. |
| Pietersburg Group xenoliths and diabase dykes | As rafts and intrusions within the gneiss | Schist, amphibolite and quartzite xenoliths are the best targets on this ground, with a success rate near 66 per cent. Dyke margins are the other target. |

Get a Polokwane Borehole QuoteWhat That Means for Your Borehole
- Nearly half of all recorded boreholes on this ground failed, which is the honest context for any quote. Across 4,833 holes in the national database, 48 per cent yielded less than a tenth of a litre per second.
- Siting is the whole difference, and it is quantified here: scientifically sited boreholes succeeded 66 per cent of the time against 49 per cent for holes sited by laypeople. That is the single best argument for a survey anywhere in the country.
- Fixed-depth contracts are a bad deal on this ground, because the productive zone is the weathered mantle and the fractures just below it. Drilling to conditions beats drilling to a contracted 60 or 90 metres.

What to Watch For Here
Yields depend on the weathered mantle and on structure, so depth alone achieves nothing. Where the weathering is thin and no fracture is intersected, a deep hole is simply a deep dry hole.
Fluoride occurs in basement groundwater in this district, and it cannot be tasted. On any hole intended for drinking, the analysis should include it.
What the Water Is Used For
- Irrigating established gardens and mature trees
- Topping up the pool, subject to what the analysis says
- Washing paving, vehicles and hard surfaces
- Standby supply when municipal water is interrupted
- Reducing a monthly municipal water bill
Wellpoint or Borehole?
No, except on narrow strips of Sand, Hout and Brak river alluvium. Water levels across the plateau sit at 10 to 40 metres, which is well beyond what a driven point and a suction pump can lift.
Water Quality in Polokwane
Calcium-magnesium bicarbonate and chloride-sulphate water with dissolved solids from 300 to 1,500 milligrams per litre. Just over 20 per cent of analyses were not potable, and nitrate above 10 and fluoride above 1.5 milligrams per litre accounted for 85 per cent of those failures. Nitrate here is largely a depth question: shallow holes near pit latrines and kraals are the problem. Hardness runs high in the peri-urban areas around Polokwane.
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
Registration for water use in Limpopo sits with the Department of Water and Sanitation through its national registration system, not with the municipality. We could not find a published municipal borehole by-law anywhere in the province, so we do not claim one exists. What municipalities do enforce is the prohibition on cross-connecting a borehole to the municipal reticulation, and their ordinary building and planning rules. 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 Polokwane
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 - R1,050 /m | Weathered gneiss drills quickly; fresh gneiss below it is hard and adds cost without adding water. |
| uPVC casing, installed, per metre | R400 - R750 /m | A steel or PVC run through the weathered collar is the controlling need. Open hole below that. |
| Mobilisation and site establishment | R2,500 - R14,000 | 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 | R65,000 - R175,000+ | 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.
Polokwane Borehole FAQs
Should I test Polokwane borehole water for fluoride?
Yes. Elevated fluoride is a documented issue in granite-gneiss groundwater across this part of Limpopo, and it is invisible and tasteless.
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.
How deep are boreholes in Polokwane?
Usually moderate. The productive zone is the weathered mantle above fresh rock plus any fractures below it, and both sit at modest depth.
Once you are into fresh unfractured gneiss, further metres add cost without adding water. That is why siting matters more than depth here.
How likely is a borehole here to find water?
Across nearly five thousand recorded holes on this basement, 48 per cent failed to give even a tenth of a litre per second. That is the real base rate and it is worth knowing.
The figure that matters more: scientifically sited holes succeeded 66 per cent of the time against 49 per cent for holes sited by eye. Siting is not an upsell on this ground, it is the difference.
Should Polokwane borehole water be tested for fluoride and nitrate?
Yes, both. Just over a fifth of analyses across this district were not potable, and nitrate and fluoride together accounted for 85 per cent of those failures.
Neither can be seen or tasted. Nitrate is largely a shallow-hole problem near sanitation and kraals; fluoride is geological and matters most for children.
