Wellington sits on the granite and Malmesbury contact with the Berg River running through it, giving three quite different drilling propositions in one municipality.
Agricultural demand dominates here, which makes the tested sustainable yield the number that actually governs the project.
What Is Under Wellington
The formations below are what a rig actually meets on a Wellington 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 | The batholith underlying the valley floors and lower slopes | Weathered mantle over fresh granite, with water in the weathering profile and in jointing. Casing through the weathered zone is standard. |
| Table Mountain Group sandstone | The mountain ranges framing the valley | Hard fractured quartzite, the principal recharge for the whole valley, and a deeper, fracture-dependent drilling proposition. |
| Alluvium and river terrace gravels | Along the valley floor and the river courses | Permeable material that can yield well at shallow depth, and the usual target where a property sits low in the valley. |

- Valley-floor and hillside properties are different projects, and the difference in cost between them is substantial.
- Agricultural demand changes the sizing exercise. Irrigating hectares is not scaled-up garden watering, and the yield test carries much more weight.
- Registered abstraction matters here. Volumes for commercial irrigation usually go beyond Schedule 1, and that is a conversation to have before drilling.
Where We Work Around Wellington
- Wellington town and Bovlei
- Hermon and the Berg River valley
- Blouvlei and the Bainskloof road side
- Groenheuwel and the northern side
- Smallholdings toward Riebeek Valley
- Working farms across the Bovlei
What to Watch For Here
Three settings, three cost profiles. Granite, Malmesbury shale and river alluvium all occur here, and which one is under your stand changes the quote substantially.
Summer irrigation demand is heavy and sustained. That makes sustainable yield rather than peak flow the figure to design against, and storage the thing that bridges the gap.
What the Water Is Used For
- Crop, vineyard and orchard irrigation
- Stock watering across camps
- Packhouse, cellar and equipment washdown
- Frost protection and establishment watering
- Household and worker housing supply
Wellpoint or Borehole?
Occasionally, on valley-floor properties with real alluvial cover and a shallow water table. On granite or on the slopes it is not an option. Worth assessing on the low-lying ground before assuming a borehole is the only route.
Water Quality in Wellington
Granite and sandstone water here is generally soft and good quality. Alluvial water on the valley floor is more exposed to agricultural land use above it, which makes nitrate worth testing for specifically wherever the hole is shallow and the surrounding land is farmed.
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 requirements sit with the local municipality and differ from the City of Cape Town's, so confirm what your municipality requires before the rig is booked. The National Water Act applies regardless: reasonable domestic use generally falls under Schedule 1, while irrigation, agricultural or commercial 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 Wellington
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 quartzite drill slowly. Alluvial valley-floor holes are faster and shallower. |
| uPVC casing, installed, per metre | R400 - R750 /m | Weathered granite and loose alluvium both require casing. |
| Mobilisation and site establishment | R3,000 - R12,000 | 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 | R90,000 - R260,000+ | 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.
Wellington Borehole FAQs
What yield can a Wellington farm expect?
It depends entirely on where the hole is sited. Alluvial ground along the Berg River can be productive at shallow depth; granite and shale positions are fracture-dependent and more variable.
A proper constant-rate yield test after drilling is what establishes the number, and it should precede any commitment to an irrigation layout.
Do I need authorisation to irrigate from a Wellington borehole?
Very likely. Irrigation volumes on a working property generally exceed what Schedule 1 of the National Water Act covers as reasonable domestic use.
That means registration or a water use authorisation from the Department of Water and Sanitation. Settle it before drilling, because doing it afterwards is harder and occasionally unsuccessful.
Can a borehole irrigate a working farm in Wellington?
Often, but the exercise is a different one from a domestic borehole. Irrigation demand is measured in thousands of cubic metres a season, and that has to be matched against a tested sustainable yield rather than a driller's first-day figure.
It also usually takes you past Schedule 1 of the National Water Act into registered or authorised abstraction. Settle that before drilling, not after.
Does a Wellington borehole need a water survey?
On granite and sandstone, yes - yield depends on intersecting structure, and geophysics is what targets it. On a valley-floor property with genuine alluvial cover, the case is weaker because the aquifer is more continuous.
The site assessment should tell you which of those you are, and a contractor who recommends a survey on every site regardless is not assessing anything.
